Thanks for your comment, Rob. You are absolutely right - actually I tried to lighten this part, but it is impossible. There is absolutely no structure in the lower part of the bird, depending on the heavy overall contrast. It is a digital one, and this is another reason for my preference to analog cams.
It is a good photo, clear and sharp, but the black feathers in the lower parts are solid black. Maybe increasing brightness and reduce contrast or levels in PS may increase the quality of the image. Regards Rob.
