I have no idea of what to do.
I have looked your photos again in the computer and the colors are weird. There seems to be a yellowish color cast in all of them
Is that the result of the post processing?
As said, you can try to shoot with an orange filter for a daylight balanced colour or to shoot in tungsten light
Or both. Maybe there's someone here with a filter to lend. On the other hand, they are not expensive.
I am willing to use mine, but I need time and a good plan for it. I wouldn't like to be some days on leave and have a tungsten balanced film inside my camera while I'm away...
