Hi Bob,
CA is short for chromatic aberation and it often occurs on the edges of brightly lit areas in a shot and is often worse in the corners and when a lens is at or near its widest aperture. Tree branches with with bright light behind them often show this artifact. It can be bluish purple, red, yellow, or green. When I look at your shot again, I think it is a reflection from the chalk not CA, but it has the same appearance to some extent--a color shft on an edge of a brightly lit object. If it were CA most post-processing programs including Adobe Camera Raw have settings that can do a lot to get rid of it. If you shoot again, if it is a reflection you can probably get rid of it by just moving the chalk about an inch back. I hope this helps,
Steve S.
I tried a couple of different shots - here's a couple more
Do you like these better?
Thanks,
Bob
