Wouldn't that be mare and foal? ;) As for the picture, the colour seems a little washed out to me. I shoot horses a lot, and I find you need to really boost the contrast (I use curves to do it) or it looks flat. Another habit of mine is to try not to cut off a horse in the midsection...I'd move the crop a little in either direction; either use a leg as a frame, or completely include or exclude them. I doubt that's an official photography rule, it's just one of mine. I like the fact that it looks as if they're hugging. Nice moment you caught here.
I don't see these as opposites and too bad the hooves are cut off, but what a great light and color and such a tender image filled with love and sweet smelling air,8
Beautiful dreamy saturation. I'd like to see a bit more contrast. Nice capture, I like the composition, though I think I could use more of the philly's midsection in the frame if possible.
