Our 20 slowest tests consume about 2 minutes of the overall 6 minute runtime for 2,000 tests. This rough power-law distribution of test runtime, appears to be common to most test suites.

original Leica 35/2 8-element VS. replica 35/2 8-element final retail version (Black Paint)
Original Leica 8-element was mounted on Leica m7, and the replica 8-element was mounted on Leica MP. Same shutter speed setting for every comparison shoots.
Film: Kodak NEW Ektachrome E100
Two films have been developed in the same batch to keep this a fair test.

John Deere 8360RT (lead tractor) under test at the University of Nebraska Tractor Test Laboratory. The instrumentation vehicle (yellow) and following tractor provide loading for the test. Part of the test involves multiple laps around the lab's concrete oval track. I took this photo while visiting the Lester F. Larsen Tractor Test and Power Museum in Lincoln Nebraska. tractormuseum.unl.edu/
NAWCAD Trenton, located in Mercer County, New Jersey, consists of about 66 acres with a total of 96 buildings and structures. The center was used to test jet engines, alternative fuels, turbines, and engine starters.
The main "hangar" at NAWCAD. Im not exactly sure what this building was used for but there are slots in the ground about a foot deep and there are spikes and stands that stick out of them. It looks like you would brace something on top of them. You can see the slots better in this picture.

Testing one, two and now, three.
Radio frequency testing has begun on the first Orion spacecraft that will fly around the Moon for the Artemis 1 mission, just two weeks after thermal and environmental tests were completed at NASA’s Plum Brook Station in Ohio, USA.
Electromagnetic compatibility or EMC testing is routine for spacecraft. All electronics emit some form of electromagnetic waves that can cause interference with other devices. Think of the buzz that speakers give out right before an incoming call on a mobile phone.
Spacecraft electronics can cause similar interference, but out in space such interference can have disastrous consequences, so all systems must be checked before launch.
EMC tests often take place in a special shielded room constructed of metal walls and doors and foamy spikes (aka absorbers) that block out unwanted external electromagnetic radiation, like ESA’s Maxwell chamber at its technical site in the Netherlands.
Though not an EMC chamber, Plum Brook’s thermal vacuum chamber is made of aluminium that does provide electromagnetic shielding, making it a suitable substitute.
To test electronics, the spacecraft will simulate a flight in realistic conditions with most of its subsystems and equipment powered and in operational mode.
The electronics are first tested for compatibility in this electromagnetic shielded chamber. Equipment will be switched on to test whether they do potentially disturb one another.
In the second round of tests, electromagnetic fields will be applied using antennas around the spacecraft to test the susceptibility to interference from external sources. The Orion capsule is equipped with electromagnetic field sensors to take measurements as the disturbance frequencies are injected into the chamber.
While all subsystems are a potential source of radio frequency noise, of particular interest are the transmitters that intentionally generate radio frequencies. These can easily disturb other equipment sensitive to electromagnetic noise, like GPS receivers, tele-command modules and other communication elements.
ESA experts are on site monitoring all tests alongside NASA colleagues as Orion moves closer to its first flight without a crew around the Moon.

SONY DSC+lampe de poche + un cône carton + papier mouchoir pour atténuer+ manteau noir pour le fond...du bricolage a l'ancienne quoi....:-D
A toy? Not really, this lens can really deliver amazingly sharp results!
--- Lessons learned:
+ best way to get the grips is to use the lens with the cam (in liveview) tethered to a tv set via DVI
+ the lens should not be used on maximum tilt -- you cannot get sharp results with this adjustment
+ the two lenses in the Lensbaby are not coated, backlight will lead to overlit blurry results ...
+ This is a 50 mm lens, minimum object distance is approx 0,6 meters ...
+ shots were take with the 4.0 aperture, ... 5.6 has a wider sweet spot, but less wow effect
+ works fine in Av-Mode
--- This is how focusing works:
Point the optical axis of the lens **exactly** towards the spot you want to focus; adjust focus ring - if possible in zoomed liveview mode.
--- This is how it not works:
Leave the lens as-is (no tilting); try to focus on an object in the corner of the image via turning the focusing wheel.
--- One problem I came across:
The 5DMkII works fine with this lens in Av mode, even better with additional liveview, but does *not* adjust exposure in *zoomed* liveview! => Firstly wait for exposure adjustment, then zoom in, adjust focus, if possible, zoom out again, shoot. :-)

Photos here were shot using old Canon FL/FD lenses mounted onto the new compact mirrorless full frame Sony Alpha A7 released on November 13, 2013 in Japan. The lenses are all manual focus due to the fact they are old legacy prime lenses. The Canon lenses used for this test:
FD 35mm, f2
FL 50mm, f1.4
FD 135mm, f3.5
FD 135mm, f3.5 (with PL filter)
This photo was taken using the portrait focal length, FD 135mm, f3.5 lens.

This is a composite iPhone photo and editing test.
The TOP image is the original iPhone image, and it is typically noisy (view full size to see noise level).
The MIDDLE was edited (levels, color balance) on the iPhone using Photogene iPhone app and still presents the same amount of noise.
The THIRD photo took the previous, Photogene altered image and, using Photoshop, ran a Reduce Noise filter with heavy settings, then doubled the image, blurred the top layer and set it to 'overlay mode' at 66% opacity. This is a pretty common method for making better, softer, smoky images. A much more rich, deep result.
iPhone image editing apps should consider adding noise reduction and automating some of the more common image enhancement tricks beyond just levels, even if they disguise it and call it something else.

Finally, one of the best ways to improve photos on the iPhone is to use an app that looks at the accelerometer to determine when you are moving the least. Try Steadycam. I use it instead of the built-in photo app.

Testing out a Roll of Adox Colour Implosion film shot at 100 ASA using a Nikon F3HP camera, Nikkor Ai 50mm f/1.4 lens, and SB-16 Flash.
The film (and prints) look this bad on purpose, when shot at 100 ASA, the film has a definite blue cast, shot at 400 ASA, a Red cast. When I picked the film up from the lab, they thought I'd been shooting 30 year old film, rather than new film.

Tested these brands and some more. Will need some time to round up the results...
Too many things too do, too little time.

Test Roll of Lomography CN 400 in my new Lomogrpahy Konstruktor DIY SLR.
Overall the pictures are okay. I don't think I'd be using it that often, the 1/80 shutter speed is just a bit too slow unless you stop and stand still.
Also it likes to eat film.
