Testing my newly-built wind generator. Built from an old washing machine motor and PVC soil pipe blades, it's intended to charge a battery to power light in a remote stables.
(p.s putting your assistants in mortal danger is NOT the correct way to test such a device)

Charlie road tests for the first time his new chair that daddy acquired as a warm inside garden observation post by the back door in preparation for the terrible winter we've been promised. ;-)
Note the freckles on Charlie boy's bottom lip. ;-)

Shot on my Canon Rebel XT with the cheapest lens available (50mm f/1.8). 19 images were stitched together automatically using Hugin to create this 37 megapixel image. The virtual sensor area is close to 6x4.5cm medium format.
Next I want to do a wide angle image with my 85mm lens, covering roughly the same surface area as 4x5. That would yield a 290 megapixel image...
I am test-riding this little number. Was surprisingly stable on the highway even on a very windy day. And it kan keep up with the other traffic quite nicely.
This would be the 'sensible' choice for me. Reasonable price, good quality, but no gizmos or 'flash'. It lacks a certain gimme-gimme factor. Hmmmm.
Have to add that the seat is super-comfortable, and the build-quality feels superb.
Testing out my Sony NEX 6 with the e mount 35mm F1.8. This was taken in aperture priority mode F2.0 at ISO 800 with a 1/30 shutter speed. I could have easily backed down to ISO 400 at 1/15 of a second. This shot was taken very quickly and I didn't spend much time composing and dialing in the settings.
This is the third test roll I run in my old Olympus Mju II, a camera that I used to be very fond of for some years, although the point-and-shoot made me a lazy photographer without any control of any parameters. After the first two test rolls I thought the visible issue on the right edge of the frame was a light leak. So I shot this roll with all the possible sources of light covered with black gaffing tape. Surprise, the problem is still there and even more pronounced and regular. I haven't got the camera with me now to investigate but it will probably have to be seen by a technician.[rb_260506_000021240027.jpg]

One of the easier attractions to theme, I would think. Everything is very industrial looking, making the whole pavilion feel like a warehouse.
This is a test of my waterproof ink pens. I found I could get a nice range of grays by using one or two coats of various inks. Some of the combinations are similar, but I can get at least seven step grayscale from the paper color to black.

Another test, this time with a different lens, and much father away.
fstop = variable, shutter = 30, 15, 8, 4, 2, 1", 2", ISO = 800
This time I used a vintage lens. This lens is pre auto anything, and is a 135mm prime, promura 2.8. It doesn't do close focusing, so I had to be at least 7 feet from the subject to focus. I had said in my earlier tests that diffraction plays a part after f11, but I theorized that when you are further away, f16, and f20 might actually be crisper. This test proves it at least part of the way.
At f2.8 my image is a mess. It's blurry, no real definition, it's just a damn mess, which is a shame because the bokeh on this lens is crazy, and has a lot of personality. The draw back seems to be of course the crazy softness. This could be due to the slow shutter speed, but the later shots were done at an even slower speed, and I saw better results the further up I went in speed.
At f4 and 5.6 the clarity takes a major jump from unusable, to pretty nice.
When I get to f8 it really starts to shine, but what surprised me was f11 and f16. F16 for the first time in all of these tests actually looks crisper than f11, and f22 aint so bad either. So this begs the question, how much better or worse will the focus get the further out the camera gets from the subject.
My next test will use the same lens, and settings, but will be from an even further distance approaching infinity.
