Don, I imported the first photo in DPPR and did the best I could with it. I then took it to LR where I was able to look at the histogram a bit better and tweak the white and black sliders. The RAW was overexposed. My camera was set to RGB as was DPP4 and LR.
My settings: 1DX with 400 f/4 II DO
ISO: 1250
560mm
f/6.3
1/640 sec.
I'm still struggling with DPP4 because I know you have to finish up in PS which, as I stated previously, I'm not comfortable with as yet (to say the least!)
Any better tonal range????
