Al Nilles submitted this image taken with a Nikon D80, with an exposure of 1/60sec at f/4, ISO 100. At first glance the white balance looks off, the roots have blue tones and there is something going on with the base of the root in the top left of the frame, probably from the flash. The blue tones don’t really bother me if that was the intent but to get more realistic root color, try to get the best white balance when taking the photograph. Of course you can always fix it on the computer especially if you have the RAW file, even with a jpeg you can work on the white balance or use a warming filter or the color balance in post processing. The composition has a nice feel to it, the different roots reaching out and the texture on the roots work together. Toss in the random leaves crawling over them and there is nice contrast and more texture from the leaves. So simple and yet visually pleasing. This is a nice start, just beware of all of the different details, in this case the white balance.
