Repair of Scanned Slide

[Jim Frazer]

Hi,

The attached image is from a slide that I scanned. The image is of my son and it was taken about 38 years ago. Somewhere in its past, something was spilled on it. I'd love to hear some thoughts on how to restore it. Some time back I tried the clone brush but the result was not good.

Thanks,
Jim

Hi, Didnt have much time to work on this photo, maybe I can get back on later, But I did get the purple out. hope this might help.

Jim, do you use Photoshop or Adobe Elements or PSP or what?

In Photoshop 7, I made a selection of your son's magenta skin and then used a Selective Color adjustment layer to reduce the magenta and increase the cyan in the Red option box. You can get pretty close to his skin color and then you can clean up with cloning, Healing and/or Patch tools. I just did enough clean-up to see that it could work. You could also convert the image to black/white and do cloning to clean up the spotted areas without having to worry as much about the color correction matching.

I read that you've been doing retouching for years, but have recently converted to digital. Let me know if you need info about my technique. I'm not versed in Elements or PSP, so don't know which tools in those programs would work like Selective Color. Welcome to RetouchPro!

Hi C.J.

I have Photoshop CS2, Elements 4.0 and Paint Shop Pro XI. I'm most familiar with the latter 2 but am working on getting my arms around CS2. I've been doing a lot of digital photography and a fair amount of retouching - more in black & white than color. This is one I did some work on a couple of years back but was reminded of it when I saw my son this weekend. Thanks for the idea. I'll give it a shot when I get some time.

Jim, there are many ways to attacking this image. However, the stain is large so the clone tool would not be my first choice. The other challenge is that the stain is darker than the rest of the face.
Examination of the individual channels holds a solution though. You will see that the stain is very prominent in the G and B channels. There is damage in the red but the luminosity of the R is very uniform. So here is what I did.

Duplicate the background to a new layer. With that layer active, go Image>Apply Image. From the dialog window, select the background layer as the source and the R channel. Make sure the blend mode is set to Normal 100% and click OK. You will end up with a Grayscale layer. Now change the Blend Mode of that layer to Luminosity. The result is attachment 1 below. The stain is still there but its brightness is the same as the rest of the face. BTW, the overall image is a little lighter than the original. If you find it too light, just do a levels adjust and pull the shadow slider a small amount to the right and you'll darken the image exactly as it was.

Now to get rid of the stain. Add a blank layer above the image and set its blend mode to color. Select a suitable soft brush set to sample all layers and lower its opacity to 80%. Use the Alt key to sample an area of normal color skin very close to the stain and release the Alt key and brush over the stain. Take a number of samples around the adjacent areas as you paint the stain out of the face and hair. It should just take a few short minutes.

Now you are left with all those spots. These can be eliminated with a combination of Healing Brush and Clone tool. I just did a little of the boy's cheek to demonstrate.
When you are done, you may need to run a noise filter on the final image to clean up any remaining noise - but you will need to see when you get there.
Good luck with the restoration.
Regards, Murray

Hi Murray,

Thanks for the ideas. I understand what you are describing. I don't have too much spare time right now but will definitely try what you suggest. I'm pretty comfortable with getting rid of the smaller speckles.

Fixing this type of problem is something that I have never been able to do successfully. The posts by C J Swartz, and mistermonday (Murry) have been most helpful and I wish to express my appreciation. Did I make it half way into the ballpark?

I have PSPv9 which I am sure has the same brushes as XI. I used the 'change to target' brush to repair the colours here...done very quickly as an example.

[Jim Frazer]

Hi dc,

Offhand I'd say you knocked it out of the ballpark! Nice job.

Ziaphra, I'll have a look to see of PSP XI has that same feature.

With the help offered here I'm sure I can get this image cleaned up. Thanks to all.

Hi Jim.

Some time ago there was a pdf file available from Russell Brown called RBStains. The tutorial was perfect for this type of damage. Unfortunately I can no longer find it on the web.

I wonder if I could use your picture for a tutorial on the repair?

Or (better still) if you upload the image to our archive. There is a thread to help here

Hi Ken,

You are welcome to use this for a tutorial. I'll have a look at how to upload the original image. It is in .tif format - will that be OK?

Jim

[Cameraken]

Hi Jim.

Thanks You.

There is No Filesize Limit if you upload it to the Archive. So a Tiff file would be great. I have posted instructions on how to upload the image at the link above.

I will post back in this thread when the tutorial is finished.

Thanks Again.

Ken.

Hi,
I'd like a chance to work on this with your permission? Thanks.

Hi Ken,

I think I uploaded the image properly, though I did it twice. I didn't see the "Pending Approval" sentence until I did the second upload. I look forward to the tutorial.

PierresPlace,

You are welcome to give it a go. I am the photographer and my son is the subject and has agreed to my posting. He looks a bit different now since he's 39!

Thanks,
Jim

[pierresplace]

Thanks,
I'll get back to you.
Best Regards,

I think I know the one you are talking about. Correct me if I am wrong but didn't it involve makng a pattern from the Red Channel, setting the healing brush to Color and selecting your newly made pattern from the Red Channel as a source. I can't remember the finer details but remember it worked quite well on red stains. I can't find it either.

By the way, great job on the damaged slide Ken. I look forward to the tutorial.

Sincerely Syd

Hi Syd.

Yes. That’s the one. Russell Brown seems to have removed it from the internet. It worked very well but maybe RB removed it because there are now other ways. Apply Image (as Murray used), Selective colour (As Carolyn used) or simply adjusting levels on the channels, and now there is Match Color for CS Users, however I did find RB’s method fascinating and I remember enough to reproduce it. I will write it up as a tutorial so that the method is saved.

Hi Jim.

I don’t see the image in the archive yet.
All images have to be approved by Doug before they become available, but your name should be showing in the ‘Last Photo Uploaded’ area (Arrowed)

Apparently the Archive will NOT accept Tiff images. The file must be a jpeg up to 500 Kb (max)
So it seems that the Tiff file has been rejected by the system.
Maybe you would like to try again with a jpeg file.

Ken.

[Jim Frazer]

Hi Ken,

Will do.

[Jim Frazer]

Ken,

I posted the image as a .jpg. The process was different this time and I can see that the image is awaiting approval.

Ken, it still exists (I made a copy just in case), just not on Russell Brown's sites. The only way I found it was using links from RetouchPro threads

RBStains.pdf -
http://www.vanwijk.com/-=%20Bookz%20...r/rbstains.pdf

[Syd]

Thanks for finding that CJ. I had a go at it using the tutorial but ended up using Curves in the end anyway. I couldn't quite get the Brightness to match exactly and that was partly because the stain is not a uniform brightness - it fades towards the hair. I suspect all those moves could be done in Apply Image anyway and it would probably be less cumbersome than defining and pasting patterns.

[Syd]

Sorry, fiddling again. I lightened the skin tones.

[Cameraken]

Hi CJ.
Great find. I searched Google and RP for that link but every link I found was dead.
With your help with the site name I found the list of all the tutorials at vanwijk
The url is
http://www.vanwijk.com/-=%20Bookz%20...ed%20Training/

I have added this link and the one direct to RBstains to our library so (hopefully) they will not get lost again.

Thanks Again. You have saved me from writing a tutorial.

Syd.

That's funny, I found it too but didn't see Ken's post of it on the 10th. Oh well, At least we have it! )
