This is how I might apply a correction.
White balance the image, Depends on the image. Colors -> Auto -> White Balance might give a satisfactory result or manually , Colors -> Levels and pick white and black points from the image.
Duplicate that and set the layer mode to Screen. Now colorize that layer, I use the GEGL filter Tools -> GEGL Operation -> Color Overlay Pick Green and adjust (to very dark green). Keep an eye on the subjects in the image. This is just a variation on a well-known procedure for underwater photos.
If more is needed, then Layer -> New from Visible and work on that
Depends on the image, if the background is a bit bright, Using Ofnuts luminosity plugin from http://sourceforge.net/projects/gimp-too...s/scripts/ ofn-luminosity-masks.zip dated 2019-12-01
It makes a selection. Background adjusted for brightness, selection inverted and contrast adjusted,
Duration 2 and a half minutes https://youtu.be/YGltUgHejco
