Take a look at the new version of the photo of Dosey Level by John McPherson posted in the gallery . I was thoroughly gobsmacked by the result and how easy it was to do.

I discovered this trick not long ago in Photoshop CC ( I expect it's in other versions, too).

Open the picture, select Image > Adjustments > Match color and tick the box Neutralize. This gives you a decent basis basis for tweaking any other parameters in the pic in whatever image processing package you use.

Many thanks to Mr McPherson for posting the original shot.

Another example to follow soon.

Here it is: Wellhope mine by staffordshirechina

After (with a couple of tweaks, but not quite fully optimised):

My photo was taken from an aging colour slide. It had lost some of its original colour range.
Your trick really does make it come back to life.
I'll have to try it on some of the others I have.
Thanks,

Hi Yorkshireman,

Fine work, I'd fiddled a bit and got nowhere near, but hadn't really had time to play at improvements. As I've just driven down and back to King's Lynn and had a boat trip out into the Wash on a shrimper/cockler I'm a little too weary to look tonight and will marvel again tomorrow.

Like staffordshirechina I have several slides which have aged poorly, sometimes I suspect it was the Agfa film stock John used which was probably for normal daylight anyway which may explain some of the problems with underground stuff.

Regards

Jim

Interesting.

You can get some fun effects with the sliders in that!

To revisit an old idea, I've found that (underground) shooting in RAW and then warming the colour temperature is the most effective tool. Mostly helps to deal with the blue tint that modern LEDs create.

Alternatively, you can just set your white balance on the camera whilst underground, to the light source you are using. Kills any blue cast given off by the LED's :)

As for colour restoration, I just start with AUTO COLOUR in the IMAGE tab drop-down menu. You can reduce the effect by going to EDIT and selecting FADE AUTO COLOUR and use the slider. This was my starting point when scanning my old slide collection (2500 odd slides) before repairing scratches and removing fungus and speckles on the scanned image.
10 months later they are looking presentable, with much of their original 'charm' restored.
Tip ; get yourself a good camel hair dust brush or a wash brush, as used in watercolour painting and dust off the slide - both sides - before scanning. It saves a lot of post scanning fannying about. 😉

Yes, cleanliness really is next to godliness when you’re scanning hundreds or thousands of slides;)

I used to have a bottle of cleaner for super 8 film that did a wonderful job, unfortunately empty now - no idea what was in it. Could it have been isopropyl alcohol?

Has anyone tried this stuff?

Seems to be what the professionals use

Kodak Film Cleaner contains heptane and 1,1,2 trichloro-1,2,2-trifluoroethane.

But the PEC12 is what the archivists use.

A mate, who used to be a film editor, warns not to go mad - don't blather it on - use very clean microfibre cloth and almost no pressure. If it's just dusty, use a tin of compressed air & leave it at that. Nothing with water or which may contain water.

Thanks nik,

Sounds good, I think I'll try it.

I had a bunch of slides that got rained on - on a light table under the open attic window - does the stuff remove dried out rain spots?
