If you mean the JPEG cpompression level of the image itself, always set the quality as high as possible. Meaning 99% if your camera allows, certainly not lower than 85% (the default for many cameras). SD cards are cheap enough. I use a card only once, keeping them as backup. For uploading to this site, I make a copy and resize (scale) the image to 1600 pixels on the long side. Rename the scaled version as such to keep the two versions clearly distinct.

The picture looks hazy. I am not sure whether I made a mistake while compressing the file or is there a problem in uploading?
