I have been shooting this deer herd for a couple weeks now, the snow today seemed to help me stay quite, I knew where they would be, and I think they were needing to forage harder due to the cold. I tried to use Final Shots focus on the snout suggestion,(great advice) and the old axiom from my underwater work which is the three rules:
Get close

f5.6 @ 1/100 ISO 100
Get Close

f6.3 @ 1/200 ISO 100
And get closer

f6.3 @1/500 ISO 100
I still haven't been able to get the big buck but his son wasn't as shy today and I was glad to get the antlers finally after about ten times at this spot at least. I missed the money shot when some ice cracked under his weight and he bolted, I was at 400 mm and couldn't find him in the viewfinder after shooting static........live and learn... the does would have eaten out of my hand today, by being still they walked to within 20 ft of me. I wished I could silence the shutter on my 20D- cold helps sound travel. Definitly thought the snow made it easier and more interesting to shoot these guys. You guys probably think I am making up this big buck by now............. All with 20D 100-400 mm IS L lens on monopod with great light. In processing I used some intentional vignetting on shots one on two to darken the corners a tad, but not much else except slight brightness/ contrast and sharpening.
C & C on these appreciated..........
