Help please on light leak damaged slide

[Bill Cotter]

I'm sure that this question must have come up before, but I couldn't find any posts on this, so please bear with me. I would appreciate any help in learning how to fix slides or negatives that have been exposed to light, probably during the loading of the film, like the one attached. This was probably a case of not advancing the leader enough after loading the camera. If anyone could point me in the right direction I would appreciate it.

Thanks

Bill

Just for fun I duplicated the file then cropping to the right side.

Then used match color with the original...got it pretty close.

Then a little healing brush and clone and noise reduction.

Hi Bill

Welcome to Retouch Pro

If you look at the channels you will see the right side of each channel is lighter than the left side.
I used levels to equal the right and left sides

Once this is done you will notice that the red channel is poor.

I used channel mixer to make a new luminosity layer from the green and blue channels.

Once the colour was put back I added a new layer to colour in the damaged areas

If you need more help take a look at the bottom of this page where pictures with similar faults are listed.

Hope this helps

Ken.

Ken, that is amazing! Would love to see you do a tute on this!

[Daviskw]

Very good job Ken...I was too lazy to recolor but even if I had I could not match yours.

Hi

Thanks for your comments Swampy and Butch.

I looked in the tutorial section and there is no tutorial on light leaks so if Bill gives his permission to use this picture I guess I could write one.

Would anyone else be interested in a tutorial?

Ken.

[Gary Richardson]

Nice work Ken, I'm sure there's a number of people would like to see a tutorial on what you did.

YES !!

You make wonderful, comprehensive, well written, easy to follow Tutorials, so Yes cubed!

[katew]

Yes please!

Ken, you did an outstanding job! I find a really high % of images requiring restoration have the problem of "tone damage", sometimes with and without color shift. Light leaks are one cause but you find the same effect on images which have liquid spills, fading due to asymetric light exposure, camera lens flare, and others. I think a tutorial would be well received and appreciated by all.

Ken, your retouch was great. Attempted to re-create but failed, so I hope you are able to do a tut. Hope Bill wasn't a 1 time poster & visitor and returns to give you permission to use the pic. I'm going to continue to bang my head against the wall until then and keep trying. Searching a few of my books to see if I find the topic discussed in one of them also. Again, great job!

Bill asked the question & with this tutorial you would give your answer.
Nice work, Ken.

[Swampy]

I PM's Bill, so hopefully he will come back and give a nod to Ken.

[Bill Cotter]

Wow! That is impressive, to say the least, Ken. I would love a tutorial on how you pulled this off, so please feel free to use the photo as part of it.

Thanks to the other posters who added advice or suggestions as well - all input has been appreciated. I'm learning just how little I know about Photoshop. Like many others, I tend to use the same tools over and over and don't touch 99% of the capability it has, so having my eyes opened like this has been something.

Look forward to the tutorial, Ken! :-)

[Cameraken]

OK.

Give me a few days.

I will post back here.

Here's a b&w version using a channel mixer adjustment layer. I took the easy way out.

[Swampy]

That is very good, Joeven. Black and white works in the time period of this shot too.

[Kraellin]

ken, you said you used levels to adjust the light side to the dark. did you mask one or both sides first?

[Swampy]

Said he would do a tute, Craig. :-)

[geezer]

Ken ~ Please post a tutorial for this. I have more than a few of these "sunburned" photos. Thanks and have a great 2008!

How to Repair a Light Leak or Stain.

This was a difficult tutorial to write because every picture is different and the methods Vary. I have tried to include more general comments which will hopefully be useful with other images.
Also I used the 100kb image in this thread but for the tutorial I used the larger image that Bill supplied so I started again with it

The tutorial is here

If you have any comments or suggestions then please post them here

Thanks for your interest.

[Kraellin]

excellent, ken! thanks

[mistermonday]

Ken, great tutorial per my comments in the tutorial thread. FYI, I found a slightly different way to solve the luminosity problem. The Blue channel had nice detail and the luminosity difference was pretty small. So I made a copy of B and performed one Levels adj on it as follows.
I did not take time to do aan accurate selection but just isolated most of the darker side with the marquee tool. I placed two eye dropper samples for the highlights in the sky (samples 1 and 2) which had levels of 192 and 212 and then placed 2 more for the mid tones on the plane's body 138 and 149. Brought up the levels dialog box and pulled the highlight slider to the left until the 192 came up to 212. Then moved the mid range slider to the right until the 114 came up to 138. The only thing that needs to be done is clone over the seam which should only take a minute or two. Making a more accurate isolation selection would have made the transition smotther. This made an excellent new luminosity layer to follow on with the rest of your tutorial.

Hi Murray.

Yes that works.

In the tutorial I blended in the Green channel as well (I discarded the Red)

If the picture were to stay in B&W it would not be required however when adding the colour back I find it is better to try to use more than one channel if possible.
This makes the colours truer and it can be quite important in some images when trying to decide what the original colour used to be.

However lightening the left side of the Blue channel instead of darkening the Right side (as I did) would probably be a better way to go and would then I would not have needed such high values when using the channel mixer.

As we know, there are many ways to achieve the same thing in Photoshop.

I tried to explain more general methods that should work with most images rather than the 'best' method for this particular image.

Thanks


And thanks Craig.

Ken.

[Bill Cotter]

Ken, thanks so much for taking the time to do this. MUCH appreciated.

Thank you so much, I really do appreciate your taking the time for this tut, it's one of the biggest problems I have with old photos.
