RE: ektachrome
I can think of two ways:

= Duplicate the layer
- Colors > Auto > Equalize...
- Turn layer opacity down to 40
- Adjust Color > levels... (bring middle triangle to the right until its less hazy)

OR

= Colors > Hue-saturation...
(two options)
#1 Adjust the hue slider to the right a little than move the lightness slider to the left a little(to give more contrast/sharpness)
#2 bring just the "saturation" slider to -50 (left)

Hope this helps

RE: ektachrome
Could I suggest a bit of pre-processing using delabratory.

looks like this

Even a 2 click stop, CMYK levels -> auto-levels, will get a result. Might not be very pretty, too much magenta, but it is starting from a low baseline.

Then if you need to, straight to Gimp (well it works here, otherwise export and re-open)

RE: ektachrome
I found this thread on my RSS subscription (Thank You, whoever set that up; I just discovered it and am learning a lot). It looked like something I've been dealing with on my own project so I decided to try the suggestions here. I've been using Levels *a lot* so I figured I might have the most success stretching the colors. My version looks a bit different from the others here so I thought I'd share it.

   

I did play with the green and blue there but I think it was too much so I added some yellow back in. There is still too much red and I've had trouble bringing that down but I don't have any more time right now, so I thought I'd at least post what I have so far. It did help that there were objects in the image whose colors I could make reasonable guesses about, like faces and uniforms - much less challenging than my Alpine mountain scene Sad .

I have to go offline now but I hope that helps.

RE: ektachrome
I made a quick compilation of my methods(found in my first post) and of's to compare.

IMO I like how natural Of's looks so I modified it a bit.
   

Drag the middle triangle in the green channel (levels...) to the left until its more green, until the skin on the soldier starts to turn just a little yellow/green(not too much.)w

Then switch to the red channel and bring the middle triangle to the right to make the colors more natural. (go too far though and the image will get dark)
