Green trees on a suburban street in the morning sunlight. This picture is straight out from the camera, no processing except darken a the brightness a bit. What I call the magic of the CCD Sensor, no longer used in digital cameras.
Made with the Pentax Optio Z-10 point and shoot.
Sensors get dirty, it is impossible to change lens and keep them clean...
Mine has to be cleaned two times a year or more.
When you choose smaller apertures, the dirt spots show shamelessly. In one of my last photos, www.flickr.com/photos/henrique_silva/6600173785/, the aperture was f/36 and so every little tiny bit of dirt was showing, I spent a little time in Lightroom cleaning them, but there are still some in the picture... It was urgent to clean the 40D's sensor
Again I went trough this delicate process, I use Sensor Scope from Delkin Devices, it works well, it uses a combination of vacuum cleaner and moistened sensor wands to get the job done. Here is a before / after mosaic, it is not completly clean, but in fact there is a compromise between having the sensor damaged or have one or two dust spots...
If you want to know more about the process, I will be happy to answer!
Check your sensor for dust!
a - Create a new image in Photoshop or any other application and fill it with white
b - Set your camera to Aperture Priority, ISO100, and aperture to it's minimum f/22 - f/45
c - Set lens focus to Manual, and focus to closest possible
d - Shoot in raw or if in jpeg, turn off special image processing functions
e - Zoom in until the photoshop image fills your camera focusing screen
f - Shoot camera facing the white image on your monitor, and during this exposure, move your camera back and fourth being careful to not to point the lens outside of your white image. You can also zoom in in the image...
g - Process your image, adjust contrast, brightness, clarity, whatever, so that you get a clear view of the dirt spots!
h - Now you can go through the cleaning process - remember that what shows on the bottom of the image will be towards the top of the camera sensor...
i - Repeat the process from a to g and if you are happy with the result, then you are done; otherwise, repeat again... this time I had to make three swab cleanings. It is preferable to clean gently several times than applying to much force.

Hatte ich folgendes nicht schon an anderer Stelle geschrieben?
1. Beim Filmtransport verschwindet der belichtete Film hinter einer Klappe, so ist er bei versehentlichem Öffnen geschützt.
2. Man spult den Film mit dem Schnellschalthebel zurück, nachdem man vorher einen Umschaltknopf betätigt hat!
3. Die Auslösung über den roten Sensor-Punkt ist wirklich sehr sanft und erschütterungsfrei.
Richtig! Diese drei exklusiven Merkmale der Selectronic Sensor findet man später wieder in den genial designten Optima-sensor-electronic-Modellen.
Der äußerliche Unterschied fällt natürlich sofort ins Auge. Die Selectronic sensor hatte die recht konventionelle, für die damalige Zeit aber moderne sachliche Form der Optima 500 fortgesetzt. Ein großer Erfolg war die die Selectronic nicht, aber das Innenleben hatte sich so bewährt, dass es mit kleinen Abwandlungen für die Optima Sensor electronic übernommen wurde.
Während aber die neuen Optimas einen voll programmierten Paratronic-Verschluss besaßen (man hatte keinen Einfluss auf Belichtungszeit und Blende), war die Selectronic sensor ein Zeitautomat: Die Blende wird vorgewählt, die Zeit dazu wird von der Kamera errechnet und eingestellt. Beide Werte sieht man im Sucher. Dieses System gefällt mir viel besser.
Es gab noch die Selectronic "S", die mit dem Vierlinser Solinar statt mit dem Dreilinser Apotar ausgerüstet war und außerdem einen Messsucher besaß.
Die Selectronic kostete 1971 349,- DM, die Selectronic S 449,- DM.
Modernized Day Sensor Assembly (M-DSA)
Modernized Target Acquisition Designation Sight/Pilot Night Vision Sensor (M-TADS/PNVS), or the “eyes of the Apache,” provides AH-64 Apache pilots with advanced targeting and pilotage in day, night, adverse weather and extreme environmental conditions. M-DSA is the latest enhancement to the M-TADS/PNVS system.
M-DSA’s Laser Range Finder Designator enhances the performance of the M-TADS/PNVS, increasing the designation and ranging capabilities of the system to fully accommodate weapons fielded today and planned for the future.
M-DSA includes an upgraded near infrared (NIR) and color sensor that allows Apache pilots to see high-resolution, high-definition NIR and color imagery on displays in the cockpit. M-DSA also incorporates additional fields of view that allow image blending with the M-TADS FLIR and enable Apache pilots to see cultural and military lighting more clearly. A new laser pointer marker improves communication and coordination with ground troops. Additionally, M-DSA incorporates an updated multi-mode laser with eye-safe lasing capability to support flight in urban environments and critical training exercises.

With its extremely high-resolution image sensor in full-frame 35-mm format and cutting-edge image-processing system, the Leica M9 is uncompromisingly dedicated to capturing images of the very highest quality. The photographer may choose between image storage in JPEG format for fast processing, or as raw data in DNG format that supports a multitude of post-processing options. Alternatively, both formats may be stored simultaneously. In the DNG format, photo- graphers may also choose between a compressed, but faster and greater space-saving option, or an uncompressed version that preserves maximum image quality.
Of course the Leica M9 offers photographers access to the complete Leica M lens system lenses, long acclaimed by experts and users as the best in the world. Its development began in 1954, and the M-System has been continually advanced and improved ever since. The high-resolution, full-format image sensor of the M9 fully exploits the performance of legendary Leica lenses from corner to corner.
It is hardly unusual that a Leica, once owned, becomes a lifelong companion. This also applies to the digital M9: Its closed, full-metal housing, crafted from a high-strength magnesium alloy, and its top deck and bottom plate machined from large blocks of brass, provide perfect protec- tion for its precious inner mechanisms. The digital components and shutter assembly of the M9 are similarly constructed with endurance in mind. Free firmware updates ensure that the camera benefits from the latest technology. In short: The Leica M9 is an investment for a lifetime.
Discretion and unobtrusiveness are particular strengths of the M-system. In operation, the shutter of the M9 is as quiet as a whisper. An extremely low noise level when cocking the shutter is ensured by a sophisticated motor and gearing system. In discreet mode, the shutter is only cocked after the photographer‘s finger is lifted from the shutter release button when, for instance, the camera is concealed under a jacket. When shooting handheld at long exposure times, or whenever extreme steadiness is essential, slight pressure on the shutter release button in ‘soft release’ mode is sufficient to trigger the camera. In addition to these advantages, the fact that the combination of camera and lens is significantly more compact than any other full-frame camera system contributes to the fact that M photographers are frequently unnoticed and often simply blend into the background.
The Leica M9 adapts to its intended uses in a seamlessly flexible manner. Its sensitivity ranges from ISO 80 for wide-open apertures on bright days to ISO 2500 for low-light image capture. Very low noise levels and finely detailed images are achieved throughout the sensitivity range, even at the highest ISO settings. Very low image noise characteristics, an extremely bright viewfinder/rangefinder, low-vibration shutter and the availability of super fast lenses make the M9 the perfect camera for available-light photography.
The Leica M9 aids photographers with automatic functions whenever they’re required, but it never dictates how to shoot or interferes with the picture-taking process. Depending on the light level, the automatic ISO shift function increases the sensitivity of the camera as soon as the shutter speed falls below a hand-holdable value. At the same time, it also limits the shift to a maximum value determined by the photographer. This means that correct exposure without camera shake and the lowest possible sensitivity is always available to guarantee the best possible image quality in all situations. In addition, the M9 also offers automatic exposure bracketing with a user-selectable number of shots and exposure increments. This function ensures that even high-contrast subjects are perfectly captured.
Like every M camera of the past half century, the M9 is concentrated, by design, on the most photographically relevant functions. Its manual focusing – based on the combined viewfinder and rangefinder concept – and aperture priority exposure mode enable photographers to achieve maximum creative expression without imposing any limitations on their creative freedom. In combination with the 2.5-inch LCD monitor on the back, the simple, intuitive menu navigation system controlled by only a few buttons ensures rapid access to the entire range of camera functions.

The CCD image sensor in the M9 was specifically designed and developed for this camera and offers full 35-mm film format without any compromises. All M lenses mounted on the M9 offer the same exact angle of view they had when shooting film material and therefore can now be used to an optimum effect. In other words, all the outstanding characteristics of Leica M lenses are now fully maintained for digital photography as well. In short, the high resolution and superior image quality of the M9 has the ability to fully exploit the enormous potential of M lenses.
In the case of the M9, it wasn’t a matter of modifying the lenses to match the image sensor, but rather the other way around. Our dedication to further developing the image sensor has resulted in a component perfectly matched to its intended role in the very compact M-System as well as to the performance of M lenses. The special layout of the micro lenses found in the M9 sensor makes it tolerant of oblique light rays impinging on its surface, thus assuring uniform exposure and extreme sharpness from corner to corner in every image. As a result, future Leica M lenses can be designed and optimized with uncompromising dedication to the achievement of the highest performance and compact construction. A newly developed sensor filter ensures the suppression of undesirable infrared light. The conscious decision to do without a moiré filter, a cause of image deterioration through loss of resolution, ensures maximum resolution of fine detail. The optimized signal-noise ratio of the CCD image sensor reduces the need for digital post-processing and ensures that M9 images possess an unrivaled and natural visual impact.
The key control element of the M9 is an intuitive four-way switch and dial combination used in conjunction with the 2.5-inch LCD monitor on the back. To set the ISO sensitivity, simply maintain light pressure on the ISO button while simultaneously turning the dial to select the required setting. All other functions important for everyday situations are quickly and easily accessible by pressing the set button: white balance, image-data compression, resolution, exposure correction, exposure bracketing, and programmable user profiles. The user profiles can be programmed with any combination of camera and shooting settings, stored under an assigned name, and accessed quickly whenever required for a particular situation. An additional pre-defined snapshot profile is also available. In snapshot mode, the M9 automa- tically sets as many settings as possible, thus providing a valuable aid to spontaneous and discreet photography. All other functions – from automatic lens recognition via six-bit lens- mount coding and selection of the required color space to cleaning of the sensor – are easily found in the clearly arranged main camera menu.
Pressing the “info” button in shooting mode displays the precise charge level of the battery, the remaining number of frames on the installed memory card, and the most important basic shooting settings, for example the shutter speed, on the camera’s brilliant 2.5-inch LCD monitor. In image-view mode, users can switch between an image-only view (with a zoom option up to single pixel level) or access other information by simply turning the dial. The available data includes information on the ISO sensitivity setting and shutter speed in use, plus a precise histogram display.
The Leica M9 embodies the heritage and amassed experience of more than five decades of the M-System. It is also, simultaneously, a digital system camera at the absolute pinnacle of modern technology. For Leica designers, photography has always been their prime concern – whether film or digital. The combination of an extremely efficient image sensor, the latest digital components, and the classic viewfinder/rangefinder principle – consistently optimized over many years – make the Leica M9 absolutely unique in all the world.

WORKFLOW SOFTWARE IS INCLUDED
The digital image processing workflow solution Adobe® Photoshop® Lightroom® is included in the M9 package.
The M9 is supplied complete with Adobe® Photoshop® Lightroom®, a professional digital work- flow solution for Apple Mac® OS X and Microsoft Windows®. The software is available as a free of charge online download for all Leica M9 customers. This also ensures that the latest release is always readily available. Adobe® Photoshop® Lightroom® offers a vast range of functions for the administration, processing, and exporting of digital images. If the images from the M9 are saved as raw data in the standardized and future-proof Adobe Digital Negative Format (DNG), then the sophisticated and precise processing options of Adobe® Photoshop® Lightroom® guarantee direct and extremely high-quality image processing with maximum image quality. At the same time, the 16-bit per channel color information captured by the image sensor is maintained throughout the processing workflow from image import to image export, ensuring that the most delicate tonal differentiations are preserved in maximum quality after completion of the post-processing sequence.
The Leica M9 can display a precise RGB tonal value histogram of the captured image after each shot, and also offers optional integration of the histogram in the automatic image view display. The clipping warning display over- and underexposed zones in each image, warning the photographer of potentially unusable images. An innovative feature is that the histogram is recalculated every time a new part of the image is viewed, thus enabling a precise quality assessment of small image areas and even the finest image details.

I have had some dust stuck on my sensor since getting my A7III and sadly the rocket blower couldn't remove it. I usually pay to get my sensor cleaned but decided to give cleaning it myself a try and I'm glad I did.

O único "problema" da viagem: Sensores TPMS a dar falso alerta pela segunda vez em 9000km, impecável!
The only "problem" in the roadtrip: TPMS with some false warnings for the second time in 9000km. Awesome!
"Magic Wire" is so called because of detecting proximity to antenna.
THE MAGIC WIRE
As shown in the diagram, the input tube is a type 6R7 duo-diode triode. The triode section forms the oscillator, in conjunction with the coil L1 which is center-tapped to the cathode. When the triode section is oscillating, the r.f. voltage developed from cathode to ground is impressed on the diode section, causing current to flow through R2 and making the diode plates negative with respect to ground. The control grid of the 25L6 power tube is connected to the diode plates of the 6R7 and consequently a negative bias is placed on the grid which reduces its plate current to a very low value. As soon as the triode ceases to oscillate, there is no longer any r.f. voltage applied to the diodes, the voltage drops and the 25L6 draws high plate current, causing the relay to operate.
It will be noted that no rectifier tube or filler circuit is required in this design, yet the instrument functions on either a.c. or d.c. On a.c., the 6R7 oscillations and the 25L6 draws plate current only on the positive half-cycles. This principle effects a considerable saving in construction cost and in the size of the instrument.
After the parts required have been obtained, the first step in building the unit is to make the chassis, which consists simply of a piece of 16-gauge aluminum or steel bent and drilled in accordance with the plan shown. The front panel, which is included with the standard 6 by 6 cabinet, is drilled and a hole and grommet are placed in the rear panel. The oscillator coil is made by winding 100 turns of No.28 d.c.c. wire on a one-inch bakelite tube 3-1/4 inches long. A tap is brought out at the center of the winding. When the winding has been completed, the entire coil is dipped in a hot half-and-half mixture of beeswax and paraffin to keep the winding in place and exclude moisture. The sensitivity of the outfit is largely dependent upon the efficiency of the coil, so it should be carefully made. C1 is mounted on a small piece of 1/8-inch bakelite, because it must be insulated from the panel.
Wire the chassis first, starting with the heater circuits. Do not connect in the power cord until all wiring has been completed. The shield of the 25L6 is connected to its cathode, the shield of the 6E7 to the heater terminal which goes directly to the line. When all the main wiring has been completed, bring the power cord through the rear panel hole, and solder the three terminals to the terminal strip. The antenna wire is brought in through a rubber-grommeted hole in the top of the cabinet and connected to the stator or plate terminal of C1. A knot in the wire will relieve any strain on this connection. Stranded wire is preferred for the antenna.
The capacitances of C1 and C2 are largely dependent upon the length of antenna wire desired. If only 4 or 5 feet are required, C2 may be omitted. On the other hand, if the wire exceeds 15 feet, C2 will have to be larger than the value given. If the capacitance of C1 were made large (say 150 mmf. or more), C2 could of course be omitted but then the adjustment would become too critical.
The relay employed is a 3,000-ohm plug-in type of standard manufacture. It is a double-pole model and will handle a non-inductive load of 100 watts. It is somewhat more sensitive than is required and any other good relay of 1,000 ohms or more resistance should be suitable. The capacitor, C4, is shunted across the relay coil to prevent chattering. It may be advisable, in some cases, to put a 0.1 mf. paper capacitor across the relay contacts to stop sparking on heavy loads. It is better practice, however, to use a separate power relay when operating any but light loads.
In operation, the antenna wire is strung out well away from grounded metal objects and a 110-volt lamp is plugged into the outlet on the panel. When the tubes have heated, the lamp should light when the antenna wire is touched. If it lights without touching the wire, C2 should be screwed down until the lamp goes out. These adjustments should be made with C1 about one-half mashed. The panel may then screwed in on the cabinet and final adjustment made. This is done by gradually adjusting the vernier knob of the dial until the light remains lit when adjusting but goes out when the hand is removed from the dial. This may be carried to a point where the light will flash as soon as one approaches within 3 feet of the wire or instrument. It is better not to aim for such sensitivity, though, since it will vary somewhat with line voltage. A good, practical and stable point is about six to fifteen minutes or so for the instrument to acquire a stable point of operation owing to its sensitivity.

Buick revived the Roadmaster name for a B-body station wagon in 1991, replacing the Estate Wagon in the lineup. Using the 115.9-inch (2,940 mm) wheelbase that was introduced for the 1977 model year, the wagon was called the Roadmaster Estate Wagon. A sedan joined the wagon for 1992, with its own distinct sheet metal, although it shared parts with other full-size GM models. The Roadmaster Estate was a badge engineered Chevrolet Caprice Estate (also sold as the Oldsmobile Custom Cruiser) the three variants differing mainly in grille design and trim. It was slightly larger than the all-new Buick Park Avenue in 1991.
Simulated woodgrain side and back panels (made of vinyl) were standard on the Roadmaster Estate, although a delete option (WB4 wood delete) was available for credit. The "Vista Roof", a fixed sunroof over the second-row seats that was not available on the Caprice, was standard as well. The Roadmaster Estate could seat up to eight with an optional third-row seat. All these wagons initially used Chevrolet's 5.0 L small-block V8, but both Buicks used the larger 5.7 L version from 1992.
From 1994–1996, the Roadmaster, like all B-Body variants, began utilizing the iron head version of the Gen II LT1 V8, its 350 c.i/5.7 liters producing 260 hp (194 kW) and 335 lb·ft (454 N·m) of torque. The switch from the Gen I TBI 5.7L V8 was due to increasing standards for emissions and fuel economy that the aging Gen I could no longer meet. This motor was shared with the Impala SS of the same era and was related to the 4.3 L/265 c.i. L99 V8 that was the base motor for the Chevrolet Caprice, and varied mainly from the F body and Corvette applications by:
A) using iron heads rather than aluminum (specified by police departments for durability and utilized throughout the B-Body line) B) a milder cam that produced a better torque curve for the heavy B-Bodies. C) various intake silencers used to make the engine more palatable to the luxury market and/or pass drive-by noise standards. D) Two bolt main journal bearing caps (also true with the F-body LT1 engines, but not the Corvette).
The Roadmaster was only delivered with the 5.7 L LT1, however, and such cars can be detected visually by a factory-installed stainless steel dual exhaust. The interior of the LT1 cars are distinguished by utilizing analog gauges rather than digital. However, unlike its stablemates, the 9C1 Caprice and Impala SS the Roadmaster was limited to 108 mph (174 km/h) due to the factory-fitted tires not being rated to run the 140 mph (230 km/h) plus the 9C1 and SS were capable of. The engine returns 17 mpg-US (14 L/100 km; 20 mpg-imp) city/25 mpg-US (9.4 L/100 km; 30 mpg-imp) highway for a 4,200 lb (1,900 kg) full-sized car (4500 lb for the wagon), up 1 mpg-US city from the previous version.
The transmission from 1994–96 was changed from the 'analog' 700R4/4L60 to the electronically controlled version of the same, the 4L60E.
Ordered with the towing package, the 94-96 Roadmaster was advertised to tow up to 5000 pounds, although the Estate Wagon owner's manual extended that to 7,000 lbs when using a weight distributing hitch, dual sway controls, increasing the rear tire pressure to 35 psi and disabling the Electronic Level Control. The tow package added 2.93 gears and a limited slip differential, heavy duty cooling system including oil and transmission coolers, and a factory installed self leveling rear suspension consisting of air shocks, a height sensor between the rear axle and body and an on-board air compressor. The most distinctive feature was the combination of one conventional fan driven mechanically from the engine alongside of one electric fan, offset to the left (non-towpack cars came with two electric fans).
GM discontinued both the Roadmaster sedan and the Roadmaster Estate in 1996, ending production on December 13 of that year. This was blamed on the smaller but more expensive and luxurious Park Avenue growing in size; the Roadmaster trim levels never exceeded that of the smaller but still full-sized Buick LeSabre, as this enabled the Park Avenue to remain as Buick's flagship car. Interestingly, both the Park Avenue and LaSabre were front-engine front-wheel drive cars, in contrast to the Roadmaster's front-engine rear-wheel drive layout. Another reason was largely a response to the SUV craze, as the Arlington, Texas factory where the assembly line that specialized in RWD cars were built was converted to truck and SUV production. Along with the discontinuation of the related Cadillac Fleetwood and Chevrolet Caprice, this signalled the end of General Motors' production of rear-wheel drive, full-size cars. When discontinued, the Roadmaster Estate and the similar Chevrolet Caprice wagon brought up the end of the era of the full-size family station wagon.

Content:
This book is unique, in that it focuses on greatly improving photography skills, both for amateurs and professionals, by understanding the image sensor & camera operation and the impact of parameters changes on image quality.
Are you one of those photographers who continuously fights excessive image noise when shooting birds-in-flight, a photographer who would like to understand why certain camera and lens settings do a great job and others don’t, or, are you a photographer who fails in creating top quality images, independent of the circumstances? Then stop looking, because you have found your comprehensively written expert guide, created by image sensor specialist George F. Vittman, PhD, who has worked with world-renowned specialists in the field since the mid-1980ies, and who is also an outstanding and award-winning photographer.
Without going into too much technical detail, this book introduces the basic image sensor operation, and it devotes a large fraction to the study of visible image noise. What is noise caused by, what is its dependence on the 3 camera exposure parameters, shutter time, lens aperture and ISO-value, how does post-processing affect noise, and most importantly, how can the image noise be minimized under different circumstances. Besides image noise, this book also reveals little known secrets regarding auto-focus, camera operation and optics, and it gives image sensor based recommendations for a camera choice in the different fields of photography.
El sensor que está en segundo plano es inductivo y detecta cuando el piñón de ataque del prelanzador está en reposo (LED verde) y cuando está accionado (LED rojo). Este único LED está encima del panel de instrumentos al lado del cuenta revoluciones del rotor y se ilumina en verde o rojo según el sensor detecta o no el piñón de ataque. Es un elemento que nos indica que una vez prelanzado, el piñón a descendido completamente y se puede iniciar el despegue al pasar de color rojo a color verde.

One of my Fuji X-Pro1 bodies is broken. It will power up, take a few shots, and then shut down. When I try to turn it on, it sometimes gives a message that says to turn the camera off and try turning it on again. I have also noticed a large, diffuse, white defect in the upper right quadrant of the sensor.
I later concluded that I had damaged my sensor while shooting a solar eclipse. Rather than repairing the camera, I decided to replace it with a Fuji X-Pro2.
