How to Sharpen

I have been shapening my photos in Photoshop for a long time. We just got a Canon EOS 10D. When I try to sharpen those photos nothing seems to happen. Why is this? Have I missed something that I should be doing with this new camera?

doug Nelson   It could be that your resolution is so high that more sharpening needs to be done before you see an effect. I have that happen with scanned negatives and slides. Read at about some parameters for sharpening with Unsharp Mask (that's the correct sharpening tool). It's better to undersharpen than to overdo it.

Diane Schull   Thanks, Doug. I will check out the website. I do use the unsharp mask tool but with these photos see almost no effect even with all three slides to the furthest right position. Thanks, Diane

Michael Kaplan   Make sure you have preview ticked to be able to see your adjustments. Also try looking at the picture at 100%. You should definitely see the sharpening effect and way before the sliders are at the right. Try for example 200%/2/0 and you should see areas sharpened. Normally you would only apply maybe 100-200/.6-1/0-2 but it depends on the image and everyone likes a different look. I once started following a thread in a forum on peoples preferences. I was amazed on the great differences that people use to acheive the same thing.
