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.

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. My portraits from this roll turned out the best.
There does seem to be a tendency to overexpose, which I'll need to work on.

Classic mirror selfie ^^
I went through some of the first photos I took with the new lens and kinda liked this.
I'm glad I bought the lens, even though I'm still struggeling with the focus at the widest apertures. This one isn't perfectly sharp where it should be, either.
