I find that textures, especially lighter ones, gets washed out and milky with the default settings for mr photographic exposure control. Pure colors, like r=1.0, g=0.0, b=0.0 looks ok, but r=1.0 g=0.5 b=0.5 looks very different in the material editor and the renderings...
If I pull the "midtones" down all the way to 0.5 (from 1.0) I get better results, but this seems very drastic (?). Then the darker details tend to get too dark :-)
The manual says that no gamma correction should be needed if using mr photographic exposure control.
Tweaking every single map using the output options also doesn't seem like a good approach.
Anyone sharing this experience?
All the best
