Say,

Are you resizing these pictures before posting? Those are some very
severe compression artifacts which destroy the image quality. And what
lens are you using? The U-2 pictures especially show a lot of purple
fringe.



They're not only being resized and compressed, but I also have to do
other stuff since many were backlit. The original image of the first
U2 pic was 3872 by 2592, and the purple fringe is evident in it when I
first cropped it to just the part of the image containing the U2
(about 16__ by 11__) , which I then resized to 1280 X 1024. The image
was then compressed for posting. Still, it actually looks a bit
better than the original in some respects.

The problems you're seeing may be more a matter of what the 75-300 mm
Sony (Minolta) lens can or can't do at full extension, with a
particularly poor light situation, instead of compression being at
fault.

Got any tips for improvement?
