Photoshop: Reduced contrast and no sharpening on sharpening layer

Photoshop CS5: I must be doing something wrong, but there appears to be an intermittent issue related to using a duplicate layer for sharpening. I use this method to have better control over the final sharpening level, apply masks, etc. With the duplicate layer selected I adjust sharpening amount (usually unsharp mask) to be more than ultimately desired. The sharpening effect looks correct when previewed. Then, when I apply the sharpening to the layer the resulting image (of the sharpened layer only) appears to have reduced contrast and no sharpening. I have checked things like blending mode, being certain I actually selected the correct layer for sharpening, etc. I don't see anything wrong. As I originally mentioned, this problem is intermittent - - - which, at least, means I'm doing something different when I encounter this problem. Please help.

Are you viewing the image at 100% zoom when previewing your sharpening?

Hello Jeffrey,

I typically view the preview window at "100%" zoom. Additionally, I have the preview box selected to see the effect on the selected image layer. In each case where this problem occurred, the sharpening in the preview window and main image were as expected. It was only after I selected "OK", to apply the sharpening to the selected layer, that the problem appeared. It is a strange effect, almost as though the inverse of sharpening was applied to the image. Once this mode is entered, the only way to clear it is to close and restart PhotoShop. I have had this problem 3 times in the last 2 weeks. Prior to (approximately) 2 weeks ago I never saw this problem with either CS2 or CS5. Thanks.

Strange. What OS are you using? (Mac or Win, Version #, etc). One guess off the top of my head is that it might be a video driver issue.

Jeffery,

I'm running Windows XP Pro (32 bit), service pack 3, on a Dell Precision 390. My graphics card is a NVidea Quadro FX 3400/4000 SDI, driver version 275.3.3.

Looks like there is a newer driver:

I'd keep an eye on it and try the newer driver if you run into the problem again.

The other option to try and narrow it down is to disable OpenGL driver for a bit to see if the problem goes away:
