I think I'm finally zeroing in on the causes of my headaches-- it looks like the image that CI is spitting back to me is using 8 bit floats. Actually, I think they're 8 bit fixed point values because I'm limited to the range of [0,1]. My Core Image patch won't give me an image back with any value less than 0.00392 (which is about 1/255). 0.002 gets rounded up to 0.00392, and dividing that number in half gives me zero. The Core Image docs say it treats everything like 128bit floats, so am I facing a hardware limitation or a QC limitation? Is there anyway to get more resolution?
