40d Sharpness Setting

If you adjust the "sharpness" setting on the 40D to 4 or 5 and take a jpeg photo under good conditions ie. adequate shutter spead, steady hand, is there any reason why you would need to run it through Unsharp Mask?

I would like to know too.

Unsharp mask reveals more details, it's like a "sharpen" that reveal hidden details.

You could
1) Set all to 0 and shoot in RAW.
2) Set it to +7 and forget it (mine is +1 saturation, +1 contrast, +7 sharpness)

But it's on my XTi.

That depends on a number of different factors:
The subject.
The target end-use; screen or print, print size, print medium.
Your attitude toward the image; snapshot or immortal art?
Your taste and standards.

Short answer, in my opinion, no.
If you are shooting jpeg, you should do everything in camera. If you are making any changes in post production, you should be shooting RAW.

There - I've said it.
