Today I tried the sharpening technique on something that I wanted. The restore is not yet done, but I wanted to show you the results when using "smart sharpening". The image on the left was put on a new background, and there is a lot of junk in the photo. The one on the right has had noise put into the background to approximate the original image. I used gaussian blur on the one on the right to get rid of some of the noise on the face, and made the mask as suggested on the original link above. I couldn't get rid of a lot of the noise on the mask, so I painted those areas with white to make the mask better. I did my sharpening in lab mode, then brought the image back to RGB. Thanks again Jeanie. This was my first attempt with it, and here is the result.

I'm impressed! I can really tell a difference. Smart thinking to clean up the mask with white - I haven't found a need to do that yet, but I thought of the same thing. Great job!

Thanks Jeanie. I didn't think you could really see the difference very easily on that one, so I'm posting a larger version of the important areas.

Actually, I could see a difference on the one you first posted. But now I REALLY see the difference! -Jeanie

I can see the deffinate difference. Thanks for showing us your results. Sometimes unless you do a comparison side by side like you just did, you don't really know how much of a difference there really is.

Very good link!There was a technique on the above mentioned site which described sharpening using a high pass filter. I tried it and got excellent results. It was also quite simple to do. I'm wondering if you tried this one also Ed and if so, how do you think it compares to the other method.
Re the various methods for fixing up an image where the subject is in the shadows I did a comparison between a few methods and had the best success with a technique described in a Kelby book on Photo Retouching. Basically you open your image,go to levels and drag the middle slider to the left to lighten the part in
shadows. Next you go to the history palette to click on the original open state Then click a soft history brush next to the "levels" state.Paint over the part in shadows only. Decrease the opacity if necessary.
I wasn't initially very crazy about this book at first but I find that I'm starting to consult it more often than I used to.It's like using an everyday cookbook .Paulette

Hi Paulette,

I didn't read the one using the high pass filter, but I have sharpened using that filter. I think it will depend on the individual photo as to if one is better than the other. The image with the link above is the only one I used the "smart sharpen" on, but I was *very* impressed with the results. That one gets a spot in my "best of" folder. Jeanie turned us on to a good one!

It's a year later, and that link appears to have vanished into cyberspace. Any clue as to what this wonderful sharpening technique was???
