Green Tint Reduction without Magenta


Recommended Posts

I don't work with photographs very often, but a couple of weeks ago I was given a very large collection of old photos that had been digitized from the original film. About 25 of these have a nasty green tint. I guess the camera was on the wrong setting(s)... I don't know.

 

Anyways, when I reduced the Green channel to a reasonable amount, parts of the photo became Magenta. :/

I wrote a script to check for Magenta's Hue range. That worked, but it also caused Reds to become desaturated. Therefore, I also had it check the Saturation amount within that Hue range.

 

Here's the script:

Set the Tint Reduction, and then lower the Red Tolerance as needed.

 

Here are some examples.

See how the Red is preserved without adding Magenta into the photo?

Afterwards, further color adjustment could done with Curves, Levels, ect.
