My camera has 3 settings for sharpness of the jpeg files it produces:- Hard, Standard, Soft. I find that if I set it to the 'Hard' setting, I do not really need to apply any further sharpening to the images - they seem really nice and sharp straight out of the camera.
I have read some advice that said to set it to 'Hard' to maintain as much information as possible. This seems to presume that the 'Soft' setting is a filtering of the original image. Other advice I have read is to set it to 'Soft', and do the sharpening yourself - to get more control over it. This seems to assume the soft image is the original and the camera applies a sharpening process to it. The middle could be true I suppose, the 'Standard' setting might be nearest the original, and the 'Hard' setting, and 'Soft' settings BOTH being a processing of the original - one each way.
Just wondering what others would do, assuming similar settings on the camera.
