The early WIP stage my WestFront44 winter map used an overcast grey high cloud cover and I tried to play with landlight & cloudshadow values to have a different feeling but it was difficult to setup that for all day duration: It's also important to test these values at very early and very late hours of the day...

The values also must be in concordance with the static-objects which use their own .mat files ! Add to that the values given by the sun (sun.java) which also sets specular, ambient, diffuze during the 24 hours of the day. Sun adds or lowers to them all, so it's VERY IMPORTANT to test all time-settings. especially the ones toward Night, because there a lot changes.

In general IL-2 maps are wrong (to dark) at anything far away from 12:00 (Noon). Therefore Sun.java must be changed to reflect more real world lighting.

The problem with IL-2 1946 is very simple: low contrast.

All you need to do is take an unedited screenshot and analyze it in Photoshop:

original:



corrected:



Its easy to correct this "low contrast problem"with a program called Gapa:



If you only change the values related to the terrain you will still have to change everything else, so why not use a global method?

If you add too much sunlight that will result in a burned image (An image is said to be burned when its original gamut considerably exceeds the target gamut, or when the result of processing considerably exceeds the image's gamut, resulting in clipping. Colloquially, an image is burned when it contains uniform blobs of color, black, or white where there should actually be detail. http://en.wikipedia.org/wiki/Burned_%28image%29 ) as it happened with the planeshine mod.

This is an example for burned out white colors, considerable amount of detail lost:

With PowerStrip is possible to export color curves from Gimp.
We can take a SC, open it in Gimp and adjust the color curves.
Then we can export the color curves to a text file.
I can open it, translate it with Libre Calc and then save it as a new option of curve in "Gamma ramp options".

It is not so easy, but we could create a lot of new curves that will be available to chose.

This is an example that I made:


I'm good in exporting curves from Gimp to PowerStrip, but I'm not so good with colors, so I almost gave up.

Regarding the colors I was using the Gamma Gapa first, but then Power Strip because I could set monitor color temperature in it.
