    Idea--Looking at autofocus from a new perspective

    Problem statement: Autofocus systems currently provide the ability to focus on the nearest subject among all active autofocus points. And although this limitation doesn't apply after autofocus tracking is initiated, this limitation does apply during the initial focus acquisition. Among...

    What lenses do you actually use most?

    I ran some statistics on my photo database to see which lenses I actually use the most, and I was rather surprised at the results. I did not expect to see that I used the 135mm f/2L so much, or that I use the 24-70 zooms so little. The data are from the most recent six-year subset of my 21-year...

    There's nothing special about this image, but it has a good combination of rather dark shadow and much brighter highlights. My 1D X arrived on Monday, but just before sunset tonight was the first time I could take it out for a spin. http://dropoff.us/private/1342061837-1-AJ9P0620.JPG The photo...

    Brightening/Correcting Underexposed Images

    Canon community: I would like your help with some mathematical/imaging research that I am doing. I am the developer for an unreleased algorithm for correcting underexposure from any type of image. I developed it on the side about nine years ago, when I was in the initial stages of some image...
