So the digital camera I have is still giving me focus problems. I know why it's not focusing properly (cheaply made fixed focus assembly) and I've tried several things in order to get it fixed, all to no avail.
So I figure I'd use XV, an image viewer and simple manipulator for X windows. It has an “Image Sharpen” option that allows you to increase the sharpness.
Anything short of 90% didn't do much. The above image was sharpened at 99%.
I actually kind of like the result, even if it is a bit odd.
