Graininess (noise): not surprising at ISO 1250, even with pushing the exposure. The problem is if you start with a dark subject you can't shift exposure enough to avoid noise completely, without clipping the highlights. No noise reduction was used, but I think I may very well be useful here. Also darkening the image a bit should help. I might add shot under overcast conditions.
Critical focus error; quite possible. I wish the bird would stand still so I could get it right!
The mention of density is something I haven't heard mention of much. Arash, you might be able to answer this question. As you increase ISO (leaving noise out of the equation) is there a corresponding decrease in density? Appreciate the feedback!!! regards~Bill
