I have an old days colour photo with some sepia / brown tint. I used Filter > Enhance > Despeckle to get rid of noise.
Is it possible to remove the brownish / sepia tint as well ? To make the photo look fresh. Thanks.

If it was a B&W picture, then Color>Desaturate, and increase contrast, with Brightness-Contrast, or for better results, with Curves.
If it was a color picture, perhaps some white balance tool that you calibrate with something that should be white or grey on the image (shirt, fridge, paper...)
I tried Despeckle, Colour temperature and Exposure tools. Exposure was most effective in making the photo look new. Colour temperature removed the sepia tone to some extent. Despeckle did a lot of help by removing the noise.
Looks like it can't be any better. I am slowly getting familiar with the tools
I've used this before on gimp :
Gimp menu : Colours / Levels
1/ Auto Input Levels
2/ if the result is not satisfied, play with the sliders on the input / output levels (red / green / blue)
3/ or 'Edit these Settings as Curves' (as Ofnuts mentioned)

This is an awesome reply. One click and you are through. Thanks.
While I avoid anything social-media-ish I will look at the gimp section of reddit, if only to smile. This one, the usual why-is-gimp-not-like-ps type of post *.

The correction procedure goes back a long way, there is even a script for it somewhere.
Starting with (1) sometimes it is enough to colour pick part of the background or...
Duplicate the layer and give a
big gaussian blur. (2) (the slider does increase past the dialogue / enter value manually)

Colour Invert that layer (3) and change the layer mode (4)

Then up to you for final tweaking. Make a New-from-visible (5) then Colour curves or Adjust Colour Levels (6) - this setting the white point.

*Because Gimp is not PS.
My photo is not very old. There is a tint of brown, yes. But it is not strong enough to be picked by a colour picker.
But above one looks like a new plan of action. I had to use " Despeckle " a couple of times as there were many grains in the photo. And " Auto Level " almost fixed it instantly as if it were a filter. Possibly because of the nature of the photo I have.
Rich, nice ! I didn't know this workflow.
