Here is a baseball individual of my son. Never really sought feedback, just sometimes looks like my shots lack something that others have.
Zach Pictures by action-photo on Smugmug
t1i w/ 85 f.18. Raw file. Post in LR. He was in a shadow on the ground with full sun behind him. OOC was him fairly well exposed, background very bright.
Don't remember exactly what the sliders were, but in general..
Exposure (ALL): -2
Contrast: slight bump up
I don't think there was much change in lights, shadows, whites, blacks.
Local brush on him to bring his exposure back up, somewhere in the ballpark of +2 or so.
Lens Correction: CA purple slider = 5 (always with this lens)
Also, for whatever I lack technically, it is 10x worse with posing. I am not great at it, so I don't communicate well what should be done, and he is impatient a lot of the time with me.
