More tests with my metal sheet. Check my photo stream for 2 others.
Strobist: 3 light set-up. SB25 with a red gel up high zoomed to 28mm, 1/8th power, SB25 with blue gel low, camera right zoomed to 35mm 1/4 power, SB800 zoomed to 105mm 1/32 power pointing straight into my face.
The difference between these two shots is the focussing of the lens. I am standing in front of the red gelled strobe.
Please let me know what you think.
Test roll 1 from the Canon EOS 3. There's a bit of a learning curve, but all in all, I'm happy with the purchase.
There does seem to be a tendency to overexpose, which I'll need to work on.

Test roll at 6x6 with a wide angle homemade pinhole camera, f90 18mm.
A few flash pinhole shots to finish the roll.
There's a saying "there's a light at the end of the tunnel", and this is the light. I am really enjoying every moment of it from the 3d tracking, live view, built, color rendition, fast FPS and etc..
Will post more pics and reviews... No PP.

A pointmap test-render from Flickr geotagged photos for Germany (only the highest geoaccuracy was used = 16/Streetlevel). The transparency of each pixel was calculated using the number of photos for the pixel's area: transparency gradually decreases from 0 to 255 photos (RGB-Range), black pixel symbolize areas with > 255 photos.
Interestingly: the Elbe river (with a famous bike track along the river through Germany) in the upper-right part, or the Rhein river bike track (left part). The coastline and alp region are densely photographed as well.
Also, check out the numbers: 87,892 photographers means 0.1 % of the total population of Germany!

Formula One Testing, Day Two, Wednesday 26th November 2014. Yas Marina Circuit, Abu Dhabi, UAE.
I tested the LumoPro LP907 Universal Hot Shoe Translator II by taking this photo. My old hot shoe adaptor is on the camera's hot shoe, and is connected to the LP907 by the audio cable visible at lower right (it came with a set of computer speakers I bought in 2000).
The LP907 fired the Yongnuo flash pictured here, which is lighting this image. (If the LP907 hadn't worked, then this image would have been dark.)
This is a test. It is meant to illustrate the differences between this really old Mamiya Macro 60mm with 42mm threads with Canon adapter lens built during the 1960's and a really new 17-55 EF-S f/2.8 IS USM.
Both images were shot wide open at f/2.8. The Canon image also had image stabilization enabled. The Mamiya image is clearly sharper. There's something either wrong with the Canon optic, or my expectations of it's performance are not aligned with the reality of new "high performance" zoom lenses... and after much deliberation and several more tests, I'm convinced the problem is in the lens.
I thought I'd give a demo of the standard vignette on the new 16-35 F4 IS L. In direct comparison to the 17-40 L which I also have, the vignette seems to be worse at first glance (back of camera) on the newer lens. However, once on screen, you can see that the newer lens is no worse at the corners than the old, and a big improvement towards the middle.
Once Lightroom releases a lens correction profile for the 16-35 F4 IS L, it should be great, as the new glass is definitely sharper, and the IS is massively useful in my opinion.
On a telephoto with IS, you're looking to get a shot with your aperture wide open, and the IS allows you to shoot at 1/30-1/100th all day. The huge benefit with IS on a wide angle for me, is that now, even though I could always hand hold at 1/15th, I can now crank up my aperture and get an even sharper image.
Overall thoroughly happy with my new glass... anyone want to buy a well loved Canon 17-40mm F4 L ?! hehe.
Test article of the Lunar Module. Built by Grumman Engineering for earth orbit testing. But Apollo 9 went so well, it was determined that another LM test was not needed. So, it chills out here in the Smithsonian.

Second post of this image but different technique ...
I used to get some nice radio programs from the ABC on my transistor during the day..
Beginning to experiment with purely digital drawing. Takes some getting used to. (See black outlines)
16 LEDs to show status on one channel of the Centipede Shield. So far they all seem to work...now, what application would be good for 64 outputs, or 64 inputs, or any mix of inputs and outputs?

went to a friend's tow pound to do some long exposure tests at night:

there is a REMARKABLE difference with high ISO noise processing set to ON.
