DDCC Project52 2014, an alphabet themed project with a new subject each week.
This is the first 'proper' camera I got to cut my teeth on. It belongs to my father, I still have it on loan... The nifty fifty attached is the main lens I use for macro work on my current 60d Eos.
Thanks Dad.

************************** NO GROUP INVITES PLEASE**********************************
Yup...its here..today i got my new toy ..its a Canon 1Ds Mark III 21.1 megapixels. full frame sensor..5 frames per second. Even at ISO 3200 i tested and there was no noise..impressive...
I also got 3new lenses to feed this hungry monster..
Canon EF 16-35mm f/2.8L II USM Zoom Lens
Canon EF 24-70mm f/2.8L USM Standard Zoom Lens
Canon EF 70-200mm f/2.8L IS USM Telephoto Zoom Lens
The question of the day is how long will it take me to learn this camera considering the fact the i hardly read manuals..i guess i am just gonna play with my new toy...sounds like fun so far. I might have to order a cart to lug my new camera and lens. boy everything weighs a ton.
My story of digital photography is not that old. Got my first digital camera, a Sony DSC F 828 three years ago and things went crazy. Every day i got sucked into digital photography more and more. Got my first DSLR camera 4 months ago. A Sony alpha A350 . it’s a great camera but it took me 3 days to realize its good for what I have paid but it’s not a pro and yes it will take miss Sony some time to come up with a real pro system. Sorry Sony guys.
Sony went back to Best buy after one week. Now questions was Canon or Nikon. And answer was not that simple since both are excellent but my research made me realize that no doubt canon is the leader. Sorry Nikon guys.
I got my first canon DSLR 40D four months ago. it’s an amazing camera , no question about that. But i guess its time for an upgrade....lol
More info Canon EOS-1Ds Mark III

This is a new lens I just bought. An Apo-Componon HM 2.8/40 from Schneider Kreutznach.
The lenses from this series are really good and are very popular among macro photographers anywhere. Even though I have the HM 4/45 I couldn't resist buying this one. It gives me one more useable stop, which can be usefull in order to avoid diffraction.
In the photo it is set up to give 2.2 times magnification.
From the bottom:
an Olympus OM MF-2 adapter
a set of Olympus OM extension tubes, 7-14-25mm (actually 14-7-25mm!)
an OM to 49mm reversing adapter
a 43-49mm step up ring
the lens itself, reversed, and finally
a 25mm M39 extension tube acting as a hood.
Taken with the Olympus OM-D E-M5 and the 60mm 1:2.8 Macro @ f/5.6, 1/20 sec, ISO200

Testing, Testing, ... BANG!!!
Nondestructive testing
Nondestructive testing or Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.[1] The terms Nondestructive examination (NDE), Nondestructive inspection (NDI), and Nondestructive evaluation (NDE) are also commonly used to describe this technology.[2] Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. Common NDT methods include ultrasonic, magnetic-particle, liquid penetrant, radiographic, remote visual inspection (RVI), eddy-current testing,[1] and low coherence interferometry.[3][4] NDT is commonly used in forensic engineering, mechanical engineering, petroleum engineering, electrical engineering, civil engineering, systems engineering, aeronautical engineering, medicine, and art.[1] Innovations in the field of nondestructive testing have had a profound impact on medical imaging, including on echocardiography, medical ultrasonography, and digital radiography.
Methods[edit]
NDT methods may rely upon use of electromagnetic radiation, sound, and inherent properties of materials to examine samples. This includes some kinds of microscopy to examine external surfaces in detail, although sample preparation techniques for metallography, optical microscopy and electron microscopy are generally destructive as the surfaces must be made smooth through polishing or the sample must be electron transparent in thickness. The inside of a sample can be examined with penetrating radiation, such as X-rays, neutrons or terahertz radiation. Sound waves are utilized in the case of ultrasonic testing. Contrast between a defect and the bulk of the sample may be enhanced for visual examination by the unaided eye by using liquids to penetrate fatigue cracks. One method (liquid penetrant testing) involves using dyes, fluorescent or non-fluorescent, in fluids for non-magnetic materials, usually metals. Another commonly used NDT method used on ferrous materials involves the application of fine iron particles (either liquid or dry dust) that are applied to a part while it is in an externally magnetized state (magnetic-particle testing). The particles will be attracted to leakage fields within the test object, and form on the objects surface. Magnetic particle testing can reveal surface & some sub-surface defects within the part. Thermoelectric effect (or use of the Seebeck effect) uses thermal properties of an alloy to quickly and easily characterize many alloys. The chemical test, or chemical spot test method, utilizes application of sensitive chemicals that can indicate the presence of individual alloying elements. Electrochemical methods, such as electrochemical fatigue crack sensors, utilize the tendency of metal structural material to oxidize readily in order to detect progressive damage.
Analyzing and documenting a non-destructive failure mode can also be accomplished using a high-speed camera recording continuously (movie-loop) until the failure is detected. Detecting the failure can be accomplished using a sound detector or stress gauge which produces a signal to trigger the high-speed camera. These high-speed cameras have advanced recording modes to capture some non-destructive failures.[5] After the failure the high-speed camera will stop recording. The capture images can be played back in slow motion showing precisely what happen before, during and after the non-destructive event, image by image.

Jahr für Jahr führt die ManpowerGroup Deutschland eine repräsentative Studie durch, in der sie Arbeitnehmer bezüglich ihrer Jobzufriedenheit befragt. Waren es im Jahr 2014 noch 45 Prozent, die mit ihrem Job unzufrieden sind, hat sich die Zahl im Jahr 2015 auf 49 Prozent erhöht, Tendenz steigend. Jedem zweiten Arbeitnehmer stellt sich deshalb die Frage: Gehen oder bleiben? Aus diesem Dilemma gibt es einen Ausweg. (wp-akademie.com)
Unzufriedenheit ist ein Gefühl, das aktivierend wirken kann
Es sind banale Gründe, aus denen die Unzufriedenheit der Arbeitnehmer resultiert. Mehr Abwechslung, mehr Anerkennung und Wertschätzung sowie bessere Karrierechancen sind die wichtigsten Motive, die in Arbeitnehmern die Bereitschaft fördern, sich beruflich umzuorientieren. Arbeitnehmer möchten gefordert und gefördert werden. Tatsächlich sind das keine Neuigkeiten, auch nicht für Unternehmen und deren Führungskräfte. In vielen Unternehmen ist eine positive Unternehmenskultur, in der Führungskräfte führen und Mitarbeiter gerne arbeiten einem Klima gewichen, in dem Machtspiele, Mobbing und Führen durch den Aufbau von Kontrolle und Druck an der Tagesordnung sind. Die Folgen sind für Arbeitnehmer weitreichend: Der Tag beginnt mit einer bleiernen Müdigkeit in Körper, Geist und Seele. Allein der Gedanke an die Arbeit bereitet Unbehagen und bestärkt den wachsenden Widerwillen. Die Frustration im Job zieht weite Kreise, und auch das Privatleben beginnt zu leiden, ganz zu schweigen von der Gesundheit. Es gibt Hardliner, die dieses Programm bis zum Ende durchziehen, während andere anfangen, ihren Job und ihr Leben in Frage zu stellen.
Sich beruflich umorientieren und den Weg der Veränderung wagen
Es gibt drei verschiedene Möglichkeiten, mit der Frustration im Job umzugehen:
1.Die Situation aussitzen, auf bessere Zeiten hoffen und die Frustration kompensieren.
2.Sich einen neuen Job suchen und diesen auch tatsächlich finden in der Hoffnung, dass in einem anderen Unternehmen ein besseres Arbeitsklima herrscht.
3.Nach einer sorgfältigen Auseinandersetzung mit der eigenen Persönlichkeit und einer Prüfung der rechtlichen und finanziellen Rahmenbedingungen den Weg in die Selbstständigkeit wagen.
Wer in seinem bisherigen Leben im Angestelltenverhältnis beschäftigt war, wird allein schon beim Gedanken an selbstständiges Arbeiten möglicherweise von nacktem Entsetzen gepackt. Der Weg der Veränderung ist ein Prozess, der schrittweise erfolgt und nicht von einem Tag auf den anderen. In einer idealen Position ist, wer den Wechsel in die Selbstständigkeit parallel zu einem festen Arbeitsverhältnis vollziehen kann.
Eine Überlegung wert: Die Vorzüge der Selbstständigkeit
Zu riskant, zu unsicher, zu anstrengend und arbeitsintensiv sind nur einige der Argumente, die die Liste der Sorgen und Ängste in Bezug auf die Selbstständigkeit anführen.
Tatsächlich ist selbstständiges Arbeiten eine Chance, die durch das Internet und den damit verbundenen Möglichkeiten auf sich, auf ein Produkt oder eine Dienstleistung aufmerksam zu machen, um ein Vielfaches gestiegen ist und eigentlich jedermann offensteht.
Die Selbstständigkeit bietet einige Vorteile: Dazu gehört eine freie Zeiteinteilung, die sich an der persönlichen Leistungskurve orientiert. Ein eigenes Business erlaubt es, der wahren Leidenschaft zu folgen und für sein Unternehmen "zu brennen", was beste Voraussetzungen für beruflichen Erfolg sind. Ein eigenes Business erlaubt es, die persönlichen Stärken nicht nur zu erkennen, sondern das zur Verfügung stehende Potenzial in vollem Umfang auszuschöpfen. Das vorhandene Wissen und die bisherigen Erfahrungswerte in Kombination mit neuem und erlerntem Wissen ermöglichen es, sich zu einem Experten zu entwickeln und sich als Marke zu positionieren. Das sichert nicht nur ein beständiges Einkommen, sondern bietet finanzielles Wachstumspotenzial nach oben.
Finden Sie, dass das gut klingt? Aber Sie haben keine Ahnung, womit und wie Sie sich selbstständig machen können? Lassen Sie sich überraschen: Die Türe für neue Wege in der Selbstständigkeit öffnet sich am 14. Februar 2017! Das ist eine Chance für Sie, den Schritt in die Selbstständigkeit zu wagen, die auf soliden und realistischen Beinen steht.
Bis dahin halten wir Sie auf dem Laufenden: Mit weiteren 10 Pressemitteilungen über "Neue Wege in der Selbstständigkeit"!

WEEK 51 – OB WM, Set III
Instead of an electronics desk, the Olive Branch Walmart just has two checkouts, kinda like you usually see in the garden center. Of course, these checkouts are the old black ones just like up front! The poster features a similarly old photograph of Don Robertson, the store manager, wearing his old Wal-Mart nametag.

These places are public so these photos are too, but just as I tell where they came from, I'd appreciate if you'd say who :)
This is a 1 watt, 110 ohm resistor that is about 12mm long. The same thing in a surface mount would be approx. 3mm long. Still amazes me!
The SL was Pentax´s last SLR without built in meter. It was built from 1968 to 1974. The SL has nearly the same body as the Spotmatic and is a real workhorse. This one is from about 1972, was used a lot - and still works perfectly.
Olbia'' ia a pseudo TLR camera I came upon this camera at a flea market and it was black with smoke it had been in a house fire so I've clean it best as i could its a 6x6cm format with shutter 25-200 speed & T,B, It was made in France originally named OMEGA but had to be renamed because of trademark infringement with swiss watchmaker Omega you can still see the old name in the back of the hood with Olbia badge in front covering up the old name c1947

The youngest asks, "Why is this computer not running, today? All the other computers are running, today...."
Electronics hobby
Designing and building a high power amplifier capable of driving low impedance (as low as 2 Ohm’s @ 50 Vpp) loads.
www.diyaudio.com/ see alias FdW
History of DIY audio
Audio DIY came to prominence in the 50s to 60s, as audio reproduction was relatively new and the technology "complex," audio reproduction equipment, and in particular high performance equipment, was not offered at the retail level. Kits and designs were available for consumers to build their own equipment. Famous vacuum tube kits from Dynaco, Heathkit, and McIntosh, as well as solid state (transistor) kits from Hafler allowed for consumers to build their own hi fidelity systems. Books and magazines were published which explained new concepts regarding the design and operation of vacuum tube and (later) transistor circuits.
While audio equipment has become easily accessible in the current day and age, there still exists an interest in building one's own equipment, including amplifiers, speakers, preamplifiers, and even CD players and turntables. Today, a network of companies, parts vendors, and on-line communities exist to foster this interest. DIY is especially active in loudspeaker and in tube amplification. Both are relatively simple to design and fabricate without access to sophisticated industrial equipment. Both enable the builder to pick and choose between various available parts, on matters of price as well as quality, allow for extensive experimentation, and offer the chance to use exotic or highly labor-intensive solutions, which would be expensive for a manufacturer to implement, but only require personal labor by the DIYer, which is a source of satisfaction to them.
At the beginning of the 90s Nikon issued two elite class compact cameras with impressive lenses, professional features and titanium bodies: the 35Ti and the 28Ti.
The 35Ti was issued in 1993 (available in chrome), the 28Ti in 1994 (available in black).
Both models are very similar and feature a realy cool and unique analoge display-system to show aperture, distance, film-counter and exposure correction values.
Lots of heavy glass and brass, but the Yashica FR II was a stripped down FR model for a lot of money. Sure, the camera could mount great Yashica/Contax lenses, flashes and even a motor winder, but it offered photographers only completely automatic exposure plus "B" and a flash sync shutter speed. Too limited for its price in 1977, which was around $225 (that'd be about $900 today).
You pick the aperture and the camera selects the right shutter speed. You hope. You do get a needle in the viewfinder to show the shutter speed selected, but only so you can judge when it's time to use a tripod. There is some automatic override via a control setting on the ASA/ISO collar around the rewind collar. It was the same as messing with the film speed. Not a feature to brag about.
The Yashica FR II kinda followed the Nikon EM way of thinking back in the day in that it offered a well-made model with limited features to get folks into the brand at a value.
The FR II can do plenty of nothing without it's 6V PX-28 (or equivalent) battery; such was the power-robbing state of electronics in the late-1970s. I sold these in a camera store in those days and few folks bought this model, opting instead to go for the next camera up the product line, which only cost a few dollars more.
This example came with a squeaky-cheap (and not too powerful) OEM brand flash unit, but with two very good Yashica lenses: a 50mm and 135mm. OK, I really bought the kit for the lenses.
This is the "Polaroid Time-Zero OneStep (SX-70 Rainbow)" camera, it is a Polaroid Land Camera that was produced by Polaroid in 1981.
This is a classic example of a Polaroid instant camera from the 1980s. The body of the camera is made entirely out of plastic. The camera features a 1 element plastic lens with a fixed aperture (f/14). An exposure compensation control dial which is combined with an “electronic eye” (light sensor) located on the front of the camera. The camera would have originally came bundled with the "Polaroid Flash Array"; which was a row of miniature flashbulbs that would have attached to the top of the camera (although other flash devices were also available at the time; such as the "Polaroid Q-light" flash attachment) This camera was meant as a replacement for the original "OneStep", which was produced from 1977 to 1980. The original "Polaroid OneStep SX-70" features a white face plate, while the later version (the "Time-Zero" shown above) had an all black chassis; both versions featured the classic Polaroid "Rainbow" stripe on the front of the camera.
The camera would have originally used Polaroid's SX-70 instant film; which is no longer produced by Polaroid. However, the SX-70 film can still be obtained through "The Impossible Project" website. The main breakthrough with the SX-70 film pack was that it allowed for a much faster development time, hence the name "Time-Zero". It also reportedly featured richer and brighter colors than pervious instant films. An interesting fact about the SX-70 series is that the actual "battery" for the camera is contained within the film pack itself. The "PolaPulse" battery is simply a thin flat 6 volt zinc-chloride battery; which was responsible for powering the internal electronics. Which includes the motors, exposure control, and light sensor; as well as signalling flash device to fire.

The Japanese-labeled version of the Nikkormat EL, introduced 1972. The first electronically-controlled Nikon SLR. This one came with this rather distressed 50mm lens, and a Nikkor 80-200 f4.5 zoom.
It took some cleaning to get it looking even this nice, and a lot of fiddling to get the electronics to wake up.

For Nikon F cameras the lenses 50mm f2 Auto S Nikkor and later 50mm f1.4 Auto Nikkor-S was standart.
Non-AI lenses fit on the Nikon F, early F2, Nikkormat FT, FTN, FT2, EL and ELW, and the Nikkorex F. They can be used without meter coupling on the earliest AI camera bodies such as the FM and FE, but they must not be mounted on later ones such as the FM2, as it is possible to damage the camera body.
Nikon brought semi-automatic aperture indexing (SAI) from the Nikkormat FTN into the professional F with the FTN finder.
The F is the first member of the long line of Nikon F-series professional level 35 mm SLRs that began 1959 and followed each other in a sort of dynastic succession as the top-of-the-line Nikon camera. The other members were the F2,F3,F4,F5 and F6 (2004–present).
The F-series do not share any major components.
All Nikon professional F-series SLRs are full system cameras. This means that each camera body serves as only a modular hub.
My old and battered noct... still working perfectly after all these years, especially wide open!
Note to self, need to use it more often, hehe...
NIKKOR - The Thousand and One Nights Tale 16 : Ai Noct NIKKOR 58mm f/1.2
The Noct NIKKOR that was said to be named after "Nocturne" was released in 1977, the same year the release of the Nikon Photomic A. This lens, as was called "Noct", was designed for taking a picture at night with fully opened aperture stop.
