"Smart Sharpening" Technique

[jeaniesa]

I was wandering around the links on the John Houston site that Chris just posted and found a great technique for sharpening. I tried it on a photo and what a difference!! Some of you may already know this technique, but I thought it was a really cool find. Between this technique and the one DJ posted for lightening dark areas, my photo retouching has just taken a huge leap forward.

Thanks Chris and DJ for sending me down this path.

I'm glad you feel like you're getting alot from this crew. I have seen that sharpening technique and think it is a good one. Thanks for posting it as I know everyone will find this a good technique for their skill library.

Jeanie,

That's a great link! Thank you very much. There is also a *lot* of other information on the home page at http://www.luminous-landscape.com/table_of_contents.htm
I could spend a lot of time there.

I already have! I thought I was going to catch up on paying bills today. Oh well - they'll be there tomorrow. Jeanie

Hey Jeanie, life's for Photoshoppin', not for paying bills.

One note for others who might download the image from the site. When I went to make a new channel, it was grayed out, and I couldn't do it. Looking to see what else was grayed out, I found many things (most) were grayed out. Aha! A clue! You have to convert the image from a 16 bit file to an 8 bit file. Then you're all set. Thanks again Jeanie, it worked very well.

I visited the site you gave and they have some good equipment reviews for those of you buying some new hardware and some interesting tutorials and lots more I didn't get to check out yet. I didn't get to really examine all of the tutorials or reviews but I plan to go back there and play around for awhile. Thanks again for the great link.

Huh. Is that what it was? I just converted the RGB file to grayscale and that worked too. Once again, many ways to accomplish the same thing!

[Ed_L]

Yeah, that's the beauty (or the problem) with Phoptoshop. Just when I think I'm doing something good, I find out there's a better/easier way to do it!

Ed

[jeaniesa]

The problem for me is that as I learn new techniques, I think back to all of the photos I've already worked on and know how much better they could be. Oh well, I guess that's the "price" of learning. (And yes, I would be quite bored with it if I thought there wasn't anything more to learn. I doubt that's going to happen for a very long time!) -Jeanie

Jeanie
You too? I have done so many pictures over the years and now I think that if I only knew then what I know now they could have been so much better. I almost wish I could go back and redo them.

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.

Ed

[Ed_L]

Here it is.

[jeaniesa]

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!

Jeanie

[Ed_L]

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.

Ed

[jeaniesa]

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

[DJ Dubovsky]

Ed
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!

Ed

[Ed_L]

Almost forgot! Thanks for the tip. I've got it copied so I can try it soon.

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

Macky

[jeaniesa]

Hmmm - I'm pretty sure I printed this off a year ago. Now, if I can just figure out WHERE I put it!!

Jeanie

I think this is it folks

Debbie

[jeaniesa]

Yes, that's the general website Debbie, but finding the actual tutorial was a bit of a challenge. After a bit of searching, it seems that the URL has changed to: http://www.luminous-landscape.com/tu...rt_sharp.shtml.

Jeanie

[nonamac]

Oh, right...high pass sharpening. Thanks, got it!

Macky

[nonamac]

Oh. NOT high pass. Very Thanks, jeaniesa!! Having the correct tut helps!!!

Macky

[jeaniesa]

Actually, this is a different method than High Pass sharpening. It uses the Find Edges filter to create a selection so that only the edges in an image are sharpened rather than the whole image. This reduces the increased grain in faces and skies that can occur with other sharpening methods.

Can someone tell me where this technique is? I clicked on the link in the original post but evidently that no longer exists. I sure would appreciate it if someone could briefly give me the steps involved, if the link is no longer available... pretty please?

Six messages back is a link that works (seven, now!)
