I would like to know a software which helps in post-production to calculate the general color/tone difference of 2 images. The images contain the same object, but arn't shot from the same position. One image might be sunny, the other cloudy, so one is more orange/yellow, the other more grey/blue, but the same object.
How would you align the tone of the image?
Background info: i shoot a couple of hundreds of images to produce textures for my models, the objects are outside, so weather conditions can change at any time, shooting must continue. I do photogrammetry, so I use the images to project them on the geometry and bake them in a UV Map. So in general I have a chunk of images made in sunny condition and another in cloudy. I would like to apply a tone to all cloudy images, having similar tone like in the sunny images.
It's not about HDR. It should be computable, not manually.
