After much trouble trying to get a texture accepted onto Texturevault, and nearly giving up on it, I finally went into their forums to ask why my photos weren’t being accepted. I had sent in roughly ten photos over the past couple months, with everything being rejected based on too much noise or not being sharp enough. When I looked at my photos, I found that all of them seemed to have the same amount of noise, same slight blur, and I couldn’t figure out how to get it any sharper. The support on Texturevault forum suggested I try an ISO of 100, and I decided to finally look up how to test for lens sharpness (which I had been meaning to do for the past month).

I found this review (http://www.kenrockwell.com/tech/lens-sharpness.htm), which seemed rather harsh to me, but I came out of it with one very particularly piece of information in mind- that lenses have a sweet spot where they will be at thier sharpest, not necessarily at the wide open apertures (which I typically like to shoot), and other apertures won’t be as sharp. Pushing a lens to its extreme will result in photos that “test the limits” and aren’t as sharp.

Keeping that in mind, I went out into the afternoon light and took a few pictures- all at ISO 100, but at 1.8, 10, and 22 apertures. Immeadietly afterwards I loaded the pictures onto my computer and looked at them at 100%. The results were surprising- I finally saw what my teachers and books have meant by Chromatic aberrations (1.8), my pictures seemed to be hopelessly blurred at 1.8 and 22, but at 10- they sharp. Not extraordinarily sharp, but definatly sharper. And there was no noise.

Woot!

I chose the two pictures that were the best and submitted them to TextureVault. This time they were accepted. I am happy to say I now have a way to test for lens sharpness, and in the meantime, I’ve just got to take more texture photos and figure out how to make sales.
