TOKYO – When Army Maj. Gen. James F. Pasquarette assumed command of U.S. Army Japan (USARJ) July 8, 2015, he immediately took initiative to personally meet the troops under his command as well as key leaders from his host nation partners.
Pasquarette's tour of his area of responsibility began in earnest when he and members of his staff boarded a UH-60 Blackhawk helicopter July 10 from Camp Zama, Japan. Flying hundreds of feet above the congested highways at sometimes at level with Japan's sea of skyscrapers, Pasquarette acquired a bird's eye view of the American and Japanese military installations scattered among the urban jungle.
“We overflew Sagami General Depot, Yokohama North Dock and Hardy Barracks, said Milton Jackson, garrison manager at Camp Zama. “Our new commander now has clearer picture of the facilities, equipment and watercraft managed by the Army, and he can better understand where and how these individual installations interact with one another.”
According to Jackson, the USARJ primary mission comprises the rapid deployment of troops and materiel from one theater to another. As the Army's largest logistical hub in Asia, the command must maintain a streamlined sustainment system capable of moving thousands of tons of supplies and equipment via land and sea.
“Sagami Depot has rolling stock and Yokohama North Dock has watercraft,” said Jackson. “We must overcome the challenges posed by Japan's dense population centers by developing methods that rapidly move and load stock onto our watercraft so that we may better project our presence in the Pacific. Fortunately, our Japanese allies are willing to support us if a major threat or disaster called for a sudden mass movement.”
After a brief stop at Yokota Air Base to meet with Air Force Gen. John L. Dolan, commanding general, U.S. Force Japan, Pasquarette touched down near the heart of Tokyo where members of America's staunchest allies welcomed him with the pomp and circumstance befitting a general.
“On behalf of the JGSDF (Japan Ground Self-Defense Force), welcome to Japan,” said Gen. Kiyofumi Iwata, chief of staff, JGSDF, to Pasquarette after the two commanders sat in a decorative conference room inside Japan's Ministry of Defense. “We look forward to continuing our dialog of bilateral coordination between our two countries as JGSDF pursues its transformation into a dynamic joint defense force.”
The dialog consisted of one-on-one conversations with not only Iwata but also Adm. Katsutoshi Kawano, chief of staff, Japan Self-Defense Force, and Hideshi Tokuchi, vice minister of international affairs, Japan Ministry of Defense. The four men discussed previous achievements, current operations and potential challenges facing their respective commands and presented ideas on how to strengthen interoperability among their forces through combined training exercises and expanded service member exchange programs.
“We currently have several dozen JSDF service members embedded with [U.S. military] units,” said Pasquarette. “I believe extending this program so that our Soldiers can work within the JGSDF will further enhance our partnership.”
Pasquarette also ensured his hosts that the United States Army remains committed to its allies in the Pacific despite looming force reductions and ongoing operations in Europe and the Middle East.
“The Army recently announced that it will cut the number of troops in the active component from 450,000 to about 410,000,” said Pasquarette. “This rebalance of the force has no effect on our strength and readiness in the Pacific. Our alliance is more important than ever. That's why we're keeping our best trained and best equipped Soldiers in Japan and Korea.”
After a two-hour visit that started with with a JSDF band playing “The Star-Spangled Banner” and ended with a warm exchange of plaques and handshakes, Pasquarette and his team boarded a helicopter bound for Camp Zama.
“I have worked extensively throughout the Pacific during my Army career,” said the former armor officer and chief of staff of U.S. Army Pacific. “The JSDF consists of some of the world's most capable and professional men and women in uniform. I look forward to building stronger relationships with them and become a valuable partner in its transformation."

Fluxus boxes were intended as non linear narratives to be handled, touched, performed, disseminated, destroyed, reassembled, counted and reconfigured.
Just as cinema montage and music had learned, the orchestration of symbols, visions and other sensorial components was able to create novel scenarios. Interactivity and tangibility created a state of continuous recombination, multiplying interpretation and cognitively activating people, who became part of the artwork while handling, imagining and communicating. The connection with the ordinary flow of life created new dimensions in the world: stratified, recombinant and engaging.
In occasion of the 50 years of FLUXUS we have decided to research on this wonderful form of expression, both for the innovation it has provided in the arts and for its connection with many of the mutation processes that are going on with contemporary humanity and their ability to experience media, communicate and interact.
At the event Mercoledì da NABA series of events, on December 15th 2010, we will hold a workshop/performance in which we will build a Fluxus Box using Augmented Reality and other cross-medial techniques and technologies.
The ojective will be to research on the Fluxus Box approach, and to appy it at a “meta” level. The objects contained in the box will be tools through which the experience of multiple Fluxus Boxes will be holdable, remixable, juxtaposable, recombinable, enacting a meta-performance encompassing possibly infinite remixed reenactments of Fluxus performances, experiences and events.
The box we will produced will be donated to the NABA, and the custom software that will be created for the occasion will be released under a GPL2 licensing scheme, so that it will be usable by artists, students and practitioners worldwide, in a further level of the performance.

Pino Morroni built components that were radical, innovative and sometimes ahead of their time. These wheels had sealed bearings and the oversized titanium spokes threaded directly into the hub flanges. The oversize spokes allowed the rear wheel to be built with a radial spoke pattern. The design objective of this wheel is to support the load from below using beefier spokes and special spoke nipples that pinch the rim ferrule in compression as opposed to by "hanging" or suspending the load like a traditional wire spoked wheel.
c1920 postcard view of North Main Street in Advance, Indiana. This view was looking south across the Central Indiana Railroad tracks and the Cross Street intersection. (Cross Street is now known as Wall Street.) Several men were sitting on benches or chairs at various locations along the sidewalks. A few other pedestrians were going about their business or watching the photographer.
The sign on the nearest building on the left (east side of the street) advertised S AND B GARAGE & HARDWARE. The 1919 Sanborn™ fire insurance map set for Advance shows a garage business at this location with a capacity of 20 automobiles. Another sign above the doorway appears to include the name OSBORNE or OSBORN’S. The only sign on the side of the building advertised ARISTO. The remainder of the sign isn’t readable, but an online copy of the sign shows this was a line of oils and greases produced by the Tiona Refining Co. of Indianapolis. One of the signs on the front of the building advertised UNIVERSAL TRACTOR. Another included the words HORSE SHOE and a third advertised GARGOYLE MOBILOILS. A gasoline pump with RED CROWN GASOLINE advertising stood in front of the building.
The largest two-story brick building in this view was on the southwest corner at Cross (Wall) Street. Of the five buildings farther south, the last two were south of an alley. The nearest of those two was brick and the 1919 map set shows the post office in that building. The map set shows a hardware, harness and buggies business in the single-story brick building north of the post office and an auto dealership and repair business in the two-story building next door. However, it is unclear if those were separate businesses or combined. In 1919, the two-story white wood frame building was occupied by a bakery and barbershop with an unidentified fraternal organization hall on the second floor. The name painted above the second-floor windows was IMP. O. R. M. (Improved Order of Red Men) HALL.
The painted sign on the side of the large building on the southwest corner at Cross Street advertised BURRIN’S and NYAL DRUG. The Burrin name was faded. T. E. Burrin had purchased the only drugstore in Advance in 1907.¹ A 1916 directory still listed the Burrin drugstore in Advance. According to the 1919 map set, a drugstore was still located on that corner. Nyal was the brand name for a group of health remedies. The I. O. O. F. (Independent Order of Odd Fellows) Hall was located on the second floor of that building. A 1927 Practical Druggist publication announced that Thomas Burrin of Advance had purchased Earl Shaffer’s drugstore in Jamestown.
The two-story building north of Cross (Wall) Street was home to a bank when the 1909 and 1919 Sanborn™ map sets were produced. The 1919 map set shows a grocery in the next building north. The display windows’ advertising appears to include the owner’s name, but it is unclear. The windows next to the grocery advertised the A OK BARBER SHOP. A hand water pump stood at the curb in front of the barbershop. The inscription above the entrance to the brick building at the right (next to the tracks) was (and still is) STATE BANK OF ADVANCE. That building didn’t exist when the 1919 map set was being prepared. Instead, the map set showed a vacant wood frame structure that was “to be torn down.” All four of these buildings north of Cross (Wall) Street are still in use.

Una storia d’amore, dolore e rabbia per una bellissima città del “mio” sud, Taranto
Oggi voglio raccontarvi una mia storia legata alla recente visita a Taranto, la “giovane Taranto antica”, come la chiamava Giuseppe Ungaretti.
La prima sensazione, scendendo dalla macchina, parcheggiata accanto alla palazzata dell’isola della città vecchia, è stata olfattiva: un odore persistente di zolfo e lo sguardo è andato subito alle famose ciminiere che, quasi tutte inattive durante il giorno, animano invece la sera di fumi e colore… non ho avuto la forza di scattare neanche una foto agli stabilimenti dell’ILVA, pur essendo una forte componente visiva della città, perché il pensiero andava alle tante, troppe persone di ogni età che hanno sofferto e soffrono le conseguenze di questa presenza ingombrante e velenosa.
Quindi, appassionati di storia, arte e architettura e curiosi di vedere e conoscere i luoghi nelle loro radici, io e Marco ci siamo subito inoltrati in un vicolo che si addentrava nel cuore antico della città. Ad ogni passo si coglieva la storia attraverso la visione di antichi palazzi dagli originali particolari architettonici e decorativi, ma, contemporaneamente, aumentava sia la percezione di abbandono, di degrado dei luoghi sia quel timore che inizi ad avvertire quando intorno a te, oltre al degrado, non vedi che qualche sparuto passante e non sai cosa aspettarti. Intanto vediamo la Chiesa di San Domenico, il Palazzo Arcivescovile e la Cattedrale di San Cataldo: bellissimi. Dopo essere anche stati inseguiti da due cani che facevano la guardia ad un cortile deserto, col cuore in gola abbiamo proseguito il nostro giro solitario. Continua sempre più la visione di palazzi spettrali, vuoti e diroccati, vicoli e palazzi con accessi murati, strutture di contenimento per evitare crolli che, come ho successivamente letto in rete, si sono succeduti anche negli ultimi anni privando non solo i tarantini, ma tutti noi di una parte di patrimonio storico e togliendo anche la vita ad alcune persone che vivevano in quei pressi (leggere gli “illuminanti” articoli corrieredelmezzogiorno.corriere.it/lecce/notizie/cronaca/... e www.siderlandia.it/2.0/index.php/se-taranto-vecchia-se-ne...). Commentiamo tra noi che se il centro città di Palermo, stupendo, ma con zone degradate e palazzi sventrati dalla seconda guerra mondiale e mai ricostruiti, ci era apparso “sgarrupato”, quello di Taranto purtroppo vive una condizione ben peggiore e condividiamo la medesima tristezza, la stessa sofferenza che troviamo sottolineata, aumentata da tanti graffiti il cui tema non appare certo ottimistico. Lo stile dei graffiti, dai colori e dall’iconografia, sembra proprio quello di “Cyop & Kaf”, impressione che avrà poi conferma cercando in rete (www.progettoalchimie.it/q-s-cyop-kaf/ e, a dispetto del nome del sito www.associazioneantigraffiti.it/2013/12/16/graffiti-e-dip... ), con i loro omini trafitti, resi minuscoli, impiccati o in procinto di farlo e disegnati spesso proprio su quei muri grigio cemento eretti per motivi di sicurezza sia per impedire di attraversare i vicoli dove le case sono crollate o stanno per farlo sia per chiudere i portali in modo da evitare anche l’accesso a quegli sciacalli che hanno già fatto razzia di beni contenuti nei palazzi antichi. Anche le vecchie porte arrugginite che chiudono l’accesso a edifici storici abbandonati e decadenti e le facciate di palazzi nascosti o affacciati sulle strade principali sono il materiale che fa da sfondo ai dipinti di “Cyop & Kaf” nella città vecchia di Taranto che, come i Quartieri Spagnoli di Napoli dove oltre 200 disegni dei due artisti sono apparsi per i vicoli e i bassi durante un periodo di tre anni, può diventare una sorta di galleria d’arte a cielo aperto. Documento tutto con i miei scatti frettolosi, ma provo dolore nel mettere a fuoco i graffiti ed il loro contesto. Vedere una città bellissima, piena di storia, una capitale della Magna Grecia, una città di quel sud a cui appartengono le mie radici siciliane mi provoca sempre un moto di dolore e di rabbia per l’indifferenza ed il silenzio generale, a livello nazionale intendo perché la rete mi ha fatto conoscere l’indignazione di cittadini, gruppi tarantini che si ribellano giustamente alla noncuranza ed all’indifferenza delle istituzioni, locali e non, anche tramite video come il documentario “Buongiorno Taranto” del regista salentino Paolo Pisanelli (il trailer potete vederlo qui: www.buongiornotaranto.it/web/promo.php; su facebook qui: www.facebook.com/BuongiornoTaranto).
Si sono fatte intanto le due e, iniziando ad avere un certo languore, cerchiamo un posto dove mangiare, ma è tutto serrato, non troviamo nulla. Proseguiamo allora verso il “mar piccolo” e, dopo esserci rifatti gli occhi con il restaurato palazzo dell’Università degli studi, con le colonne doriche del tempio di Poseidone, o forse di Diana, e con il castello Aragonese, arriviamo ad un bar. Beviamo qualcosa e chiediamo alla proprietaria del bar e ad un suo cliente se ci possono indicare un posto, una trattoria, una focacceria dove poter mangiare, ma la risposta è negativa. All’improvviso la signora ci propone una spaghettata con cozze cucinata da lei avendo già preparato il sugo per il marito. Ci guardiamo, il posto non ispirerebbe una grande fiducia nel risultato dell’offerta, ma, vista la spontaneità ed il calore della signora ed essendo noi privi di preconcetti e pronti sempre a provare nuove avventure, diciamo di si alla proposta. Ci accomodiamo quindi in una saletta del bar con televisore, del quale ci viene subito fornito gentilmente il telecomando, frigo grande a vista con bibite, pile di casse della tarantina birra Raffo, la “birra dei due mari”, che ordiniamo ovviamente, ed accompagnamento di chiacchiere con il cliente di cui sopra che ci racconta di lui che, con figli e nipoti, è l’unico dei suoi dieci fratelli a vivere ancora nella città vecchia perché il resto della famiglia si è sparpagliato tra la Puglia e l’Italia. Parliamo appunto della città vecchia manifestandogli le nostre considerazioni ed anche il nostro timore, essendo anche memori di com’era la situazione di Bari vecchia prima della “bonifica”, ristrutturazione e rivalutazione. In risposta riceviamo sia l’invito a farci da guida nella città vecchia sia la possibilità, girando da soli, di rispondere ad un eventuale malintenzionato di essere suoi amici, essendo la sua famiglia rispettata da tutti. Nel frattempo il figlio della signora, con due occhi scuri vispi e curiosi, apparecchia il nostro tavolo come può teneramente fare un bambino che fa suo un compito da adulto ed arriva una prima portata inaspettata, fettine di salame piccantello con formaggio saporito, seguita da una seconda altrettanto inaspettata, un appetitoso sautè di cozze. Arriva per ultimo il piatto originariamente proposto, una montagnola di spaghetti con un’infinità di cozze succulente. Che dire, ottimo è dire poco! Scopriamo quindi, dopo i nostri complimenti vivissimi alla signora, che lei ha lavorato per trent’anni nella ristorazione e che il suo sogno, purtroppo non avverato, era quello di aprire un ristorante. Un peccato davvero! Il marito, che nel frattempo era arrivato, scherza sul fatto di aver mangiato noi il sugo preparato per il suo pranzo e ci fornisce il suo numero di cellulare nel caso in cui volessimo tornare a gustare un piatto, un qualsiasi piatto ci venisse voglia di mangiare.
Come ho letto in un articolo di febbraio scorso sulla città vecchia che vi invito a leggere (corrieredelmezzogiorno.corriere.it/lecce/notizie/cronaca/...): “È un mondo a parte l’isola (la città vecchia). Una zona franca dove s’incontra la bellezza dell’ingenuità della gente, rimasta attaccata alle tradizioni e all’ospitalità, dove si assiste a scene di un’Italia povera e dimenticata, come quella descritta da Carlo Levi in Cristo si è fermato a Eboli, o il brutto delle favelas di Rio o di Scampia.”.
Ci guardiamo davvero soddisfatti, sorpresi e contenti di aver accettato l’invito. L’avventura, come quasi sempre è accaduto, ha avuto il lieto fine agognato permettendoci ancora una volta di conoscere l’essenza e non l’apparenza di persone semplici, ospitali e piene di calore… nui simm' 'ro Sud!
Un’ultima considerazione: come diceva Giulio Carlo Argan, “La questione del centro storico tarantino è una questione di importanza nazionale e non soltanto locale. Si tratta di conservare un complesso monumentale che interessa tutto il Paese e alla cui conservazione tutto il Paese deve concorrere.”. Chissà se qualcuno se ne ricorderà... prima o poi...
ESO has utilised the innovative technology of 3D printing to manufacture moulds for the casting of two new components required for the MUSE instrument on ESO's Very Large Telescope (VLT) in Chile. This technique offers great promise in the manufacture of complex custom items, which are often needed in astronomical instrumentation, delivering the components more quickly and cheaply and with greater flexibility. The component, the structural body of a new sensor arm, appears in the centre of the picture and is the mounting point for three mirrors.

Aquí comienza este libro. En este capítulo describiremos los componentes de la cámara. Si bien es fundamental conocer estas piezas recomiendo que no se pierda demasiado tiempo en este capítulo. Una de las bondades de la fotografía de hoy en día es que se puede llevar a cabo sin mucho conocimiento técnico. Se puede aprender mucho del funcionamiento de una cámara con solo presionar el botón disparador u obturador. Creo que para aquel que comienza a adentrarse en el mundo de la fotografía es suficiente conocer las partes principales de la cámara para pasar al siguiente capítulo. Mas adelante podrá volver aquí para fijar nombres y conocer elementos más específicos. Como ya saben hacemos todo lo posible por brindar la información que tenemos de la forma más apropiada pero está en ti la capacidad de recorrer este libro de forma dinámica y de aprovechar lo que te brindamos.
[editar]Origen de la Cámara Fotográfica
La cámara fotográfica se ha usado desde el renacimiento. Se conocía como cuarto oscuro, y consistía en una cámara oscura con un orificio muy pequeño en la parte frontal, enfrentando al sujeto que se encontraba fuera de ella. Una imagen invertida se proyectaba en la pared opuesta la que era trazada manualmente.
[editar]Cámara Estenopeica
También llamada cámara de tarro, es una de las cámaras más simples que existen, ya que no posee lentes ni controles de exposición. La luz produce una imagen que pasa a través de un pequeño agujero y se proyecta en la cara opuesta de la cámara donde se coloca un papel fotosensible. La velocidad de obturación se regula manualmente destapando el agujero durante el tiempo deseado. Esta cámara nos permite entender cuales son los principios básicos por los cuales existe la fotografía.
[editar]Componentes de la Cámara
El propósito de una cámara, ya sea compacta, digital o réflex es proyectar la luz en una superficie que pueda capturar la imagen. La acción por la que una cámara permite la "impresión del material sensible" se llama exposición. La forma en que una cámara regula el nivel de exposición es a través de tres variables que la mayoría de las cámaras comparten. Estos tres controles principales son:
Velocidad de Obturación - Es el tiempo durante el cual la luz pasará a través del objetivo. La película o el sensor se verá expuesto a mayor cantidad de luz a medida que la obturación sea más larga, produciendo una imagen de mayor exposición (más luminosa).
Apertura del Objetivo (apertura del diafragma) - Es el tamaño del orificio detrás del objetivo. A mayor apertura, entra mayor cantidad de luz a través del objetivo, produciendo una imagen de mayor exposición (más luminosa). La apertura se controla mediante el diafragma.
Sensibilidad (ISO) - Es la sensibilidad de la película o sensor. Tradicionalmente no es un control de la cámara, sino que se refiere al tipo de película usada. Pero en cámaras digitales el equivalente a la sensibilidad de la película es el sensor de la cámara. Por ejemplo, una película de 800 ASA es ocho veces más sensible a la luz que una de 100 ASA. Normalmente un nivel ASA más alto es útil en lugares con luminosidad más baja.
Examinemos los distintos tipos de cámaras que existen y dónde podemos encontrar dichos controles:
[editar]Cuerpos
El cuerpo de la cámara es el lugar desde donde se controlan la mayoría de las funciones y es el lugar donde se encuentra el material sensible y el obturador que controla si el material sensible se encuentra o no expuesto. Por esto, separar el cuerpo del objetivo no tiene ningún efecto sobre el material sensible (un rollo no se velaría).
[editar]Clasificación
SLR (Single Lens Reflex) Este tipo de cámaras cuentan con un pentaprisma que muestra en el visor exactamente lo mismo que va a ser plasmado en la fotografía final. La imagen captada por el objetivo llega al pentaprisma tras dos reflexiones. Después de atravesar el objetivo, la luz llega, en un primer momento al espejo interno y de ahí se refleja y forma la imagen sobre una pantalla mate. La imagen formada sobre la pantalla mate es recogida por el pentaprisma que corrige las inversiones, tanto la lateral como la vertical. La imagen que se ve a través del visor es la que devuelve el pentaprisma. Cuando se dispara la foto, al tiempo que se abre el obturador, el espejo interno se levanta de modo que la luz ya no se desvía en dirección a la pantalla mate ni al pentaprisma, sino que imprime directamente el negativo (o sensor en el caso de las cámaras DSLR). De este modo el fotógrafo puede ver claramente la profundidad de campo y el enfoque que está entregando el lente, con un botón de vista previa que está incluida en la cámara.
TLR (Twin Lens Reflex) Las cámaras TLR llevan dos objetivos idénticos, uno sobre el otro. Los dos objetivos son gemelos en cuanto a apertura y distancia focal, se diferencian solo en que el superior carece de diafragma y obturador. Este objetivo sirve para formar una imagen sobre un cristal horizontal situado en la parte de encima de la cámara. La postura idónea que ha de adquirir el fotógrafo es situar la cámara en su cintura y mirar desde arriba.
[editar]Objetivos
Los lentes son objetos transparentes de plástico o cristal natural o sintético. Por su forma pueden ser cóncavos, convexos o planos. Los cóncavos tienen forma lenticular (como lenteja) gruesos al centro y delgados en los bordes, también llamados positivos. El lente más popular que conocemos es la famosa "lupa". Los convexos o negativos, son delgados al centro y gruesos en los bordes. Los lentes planos reciben el nombre de filtros y los hay para corregir color, modificar texturas, etc.
El término "lente" se refiere a una pieza y "objetivo" a un grupo o conjunto de lentes. Sin embargo es frecuente usar las dos palabras indistintamente y está aceptado. El término objetivo se aplica al conjunto de lentes que va dirigido al objeto. El término ocular se refiere al conjunto de lentes que se dirigen a nuestro ojo. La cámara fotográfica, el microscopio o el telescopio tienen objetivo y ocular. En algunas cámaras digitales el ocular ha sido sustituido por un display.
El lente u objetivo es la parte más importante de una cámara. Cuando de elección se trate, si prefiere calidad, elija el objetivo de marca más renombrada. De esa calidad dependerá en gran medida la calidad de las imágenes que se capturen con ellos.
Uno de los mejores lentes que se han producido hasta la fecha son de cristales naturales de una región alemana llamada Jena y son fabricados por la empresa alemana Karl Zeiss. Esta marca da una plena garantía de calidad. Desgraciadamente su precio es alto. Los usan las cámaras Leica (alemana), Hasselblad (sueca) y Contax (alemana - japonesa) entre las principales, Sony (japonesa). Las cámaras Hasselblad fueron usadas por los astronautas norteamericanos durante la conquista de la Luna.
Se denomina objetivo al conjunto de lentes convergentes y divergentes que forman parte de la óptica de una cámara. Existen diferentes tipos de objetivos y cada uno de estos tiene distintas características:
Distancia focal: Determina el ángulo de visión de un objetivo
Apertura máxima de diafragma: Indica cuan "luminoso" es un objetivo
Marca y modelo: No cualquier objetivo sirve para cualquier cuerpo
Diámetro: Determina el diámetro de los objetivos que se le quieran adosar estos si son compatibles entre marcas y modelos
Además distintos objetivos tienen distintas calidades ópticas pero esto no se expresa en forma numérica.
Otras características de los objetivos:
Número“f”. El significado del número “f” es el número de diafragmas que caben en la distancia focal de un lento u objetivo. Se le identifica con la letra "efe" minúscula. Es una unidad de medida que se expresa con número fraccionario (quebrado) y sólo se menciona el denominador. f 2 significa: f 1/2, f22 significa f 1/22. Mientras más chico es el número "f" es más grande la magnitud del diafragma. El número “f” de un lente es el máximo diafragma al que puede abrir. Los lentes con número “f” pequeño captan más luz que los de “f” grande. Los objetivos con mayor luminosidad de "f" grande son más caros. De los datos impresos que se incluyen en los objetivos están: Máximo número "f", distancia focal y diámetro de la rosca del lente. El diafragma expresado por el número "f" está íntimamente relacionado con la “profundidad de campo”
Distancia focal. De un lente u objetivo es la distancia medida desde el centro hasta el plano en que se forma la imagen.
Tomando en cuenta la distancia focal de un lente se clasifican en: Normal, gran angular y teleobjetivo.
[editar]Clasificación
Se los clasifica según la distancia focal:
Objetivos normales: Con un ángulo de 46º se asemejan a la visión del ojo humano. Su utilidad se centra en la representación de escenas sin carga dramática. Su profundidad de campo es moderada. No suele presentarse distorsión de la imagen como en los angulares. Generalmente se habla de un objetivo de 50mm como un objetivo normal en una cámara de 35mm.
Objetivos gran angulares: Objetivo cuyo ángulo es mayor al del objetivo normal. Suelen utilizarse para planos generales donde es necesario abarcar un gran ángulo de visión o para realzar o distorsionar ciertas características del sujeto. Su característica principal es que proporcionan gran profundidad de campo y abarcan un amplio ángulo de visión. Suelen distorsionar la imagen haciendo que las líneas verticales pierdan su paralelismo y al mismo tiempo representan exageradamente los objetos más cercanos haciéndolos aparecer de un tamaño mucho mayor que el real.
Teleobjetivos: El ángulo de visión es menor que el del objetivo normal. Permiten acercar objetos situados a grandes distancias. Así consiguen aumentar el tamaño de las imágenes respecto al objeto real. Por el contrario su profundidad de campo es reducida y su punto de enfoque crítico.
Objetivos zoom: Son objetivos de distancia focal variable. Destacan por su comodidad ya que evitan el cambio de objetivos de distancias focales fijas (angulares, normales y teleobjetivos). Suelen presentar la desventaja de no contar con aperturas muy grandes o de presentar una calidad de imagen inferior, ya que su construcción es más compleja que los objetivos de distancia focal fija.
Objetivos macro: Permiten el enfoque a muy corta distancia. Se utiliza para objetos muy pequeños situados a poca distancia del lente.
Objetivo ojo de pez: Se trata de un angular extremadamente amplio, llegando incluso hasta los 180º. Proporcionan una profundidad de campo extrema, y las imágenes se ven curvas como si estuvieran reflejadas en una esfera.
El Lente Normal: Tiene la misma distancia focal de la diagonal de la película o LCD (es.wikipedia.org/wiki/LCD). Para la película de 35 mm el lente normal es de 50 mm. Es el lente con el que se equipa a la mayoría de las cámaras. El ángulo de visión coincide con el del ojo humano. Es el lente más usado. Es el lente más versátil. En él se ha conseguido obtener la menor incidencia de aberraciones.
Lente gran angular: El término se refiere a aquel cuya distancia focal es menor a la diagonal del formato de la película. Para una película de 35 mm un gran angular mide menos de 50 mm. Se usa principalmente para fotos arquitectónicas o en lugares estrechos, así como para hacer ciertos efectos. Tiene una gran profundidad de campo. Exagera la perspectiva haciendo ver muy grandes los objetos cercanos y extremadamente pequeños los objetos lejanos. Son muy luminosos. Es frecuente que no tengan completamente corregidas la aberración esférica, la aberración cromática y el astigmatismo.
El Lente Telefoto: Es aquel cuya distancia focal es mayor que el doble de la distancia focal. Se puede considerar telefoto aquel lente que mida más de 100 mm. Se usa principalmente para fotografiar objetos lejanos. Los más grandes llegan a medir más de 1,000 mm. (1 metro) y son muy poco luminosos, caros y pesados. El lente de 135 mm es el más adecuado para foto de retrato, ya que no altera las proporciones de la cara. Estos lentes producen el efecto de hacer que los objetos geométricos tengan el punto de fuga invertido, es decir que en vez de fugar hacia atrás fuga hacia adelante. También dan el efecto de comprimir la escena de modo que parece como si las distancias entre los elementos estuvieran más cerca uno de otro de lo que realmente están y los objetos lejanos aparentan estar más cerca de lo que realmente están.
Lente Zoom: Hay otra clasificación que corresponde a los lentes zoom o de distancia focal variable. No son recomendables para fotos de calidad, ya que tienen un exceso de aberraciones. Sin embargo el público en general los prefiera ya que prácticamente tienen 3 lentes en uno y son cómodos para encuadrar sin cambiar la distancia entre el fotógrafo y el modelo. También son cómodos al viajar.
For those of you who are interested in the 'bits', here are a selection of the key parts.
Not a complete rundown by covers the main mechanicals and load-bearing structures.
Car is 'drivable' with rear engine/transaxle, front tub and front drive assembly module.
Engine is an eight cylinder in 'W' format. That is two Vee-fours with their crankshafts gearedto a cenntral drive shaft.
Front and rear suspension are both by swing axles and sprung by torsion bars. The front suspension module plus straing into the front of the stressed tub and is completely self contained for load paths. The rear suspension feefs the loadparths into the engine assembly.
Not on the engine module the heat exchangers mounted in front of the rear wheels as well as behing the rear suspension module. The real Veyron has 13 heat exchangers in all. The detailing on the top of the engine asembly replicates the intake system and air-air intercoolers for the charge air.
One of the included images has the entire vehicle assembly arrayed.
Please feel free to ask any questions or request further techincal information regarding the model.

Floating in space like a cosmic jellyfish…
This is one of the most famous supernovas, SN 1987A. These remains of an exploded star have been well-studied since their discovery in 1987.
Webb’s sensitivity and resolution has given us the most clear and detailed look yet, revealing a new feature: small crescent-like structures thought to be a part of the outer layers of gas shot out from the supernova explosion.

Image description: A supernova with its components labeled. The center of the image contains a dense green cloud, shaped like a keyhole. A white line points to this area, labeled “inner ejecta (keyhole)”. Outside of this region are two, curved dotted lines with a white line pointing to the left one, labeled “crescent”. Outside of this cloud of gas is a ring of dense orange gas and dust that becomes more diffused as it travels further away from the center. A dotted blue line is overlaid in the center of this ring with a blue line that is labeled “equatorial ring”. The innermost part of this dense orange ring contains brighter orange clumps of glowing gas. There is a gray line pointing to one of these hotspots labeled “equatorial ring hotspots”. Outside of these structures, both above and below them, are very faint orange rings of gas and dust. They are overlain with dotted lines and both have white lines pointing to them, labeled “outer ring”. There are several white stars are strewn throughout the image.
Compass Arrows, Scale Bar, and Color Key
At the bottom left are compass arrows indicating the orientation of the image on the sky. The north arrow points in the 11 o’clock direction. The east arrow points toward 8 o’clock. At the lower right is a scale bar labeled 1.5 light-years. The length of the scale bar is approximately one-fifth the total width of the image. Below the image is a color key showing which NIRCam filters were used to create the image and which visible-light color is assigned to each filter. From left to right, NIRCam filters are: F150W is blue; F164N is a greenish blue; F200W is light blue; F322N is yellow; F405N is orange; and F444W is red.
