I suppose you shot this outside on a sunny day? the snow and batt tops are reflecing the blue sky. Snow is supposed to be white, not blue. proper WB and exposure would have made this so.
Oh, isn't this fun? All of the elaborate setups we go thru just to get a photo. He-he. This one works pretty well. Nice fade from front to back. Subjects are well positioned overall. Might have wanted to adjust the color temp a little to knock down some of the blue cast. Best of luck to you in the challenge.
I'm jealous of your snow! I wish we had some here.
Interesting photo, shows much more creativity than the standard 'batteries standing on end' shots all throughout the challenge. Focus is slightly soft on the first battery, which will probably hurt you a little, but otherwise I think it's a nice little image :)
