I took this photo of a bird recently. The lighting was very poor (late afternoon, trees blocking the sunlight). As a result the entire scene (in real life) looked a little poor, especially the bird's dull feathers. I tried to improve the photo a bit, but I can't seem to do it properly. It was taken at -1/3 exposure and no flash, with a Canon A520 (digital point n shoot). Is there any way I can improve these greyish scenes, or should I have waited for better lighting?
