Loving the focal length, it seems like a healthy meduim between wider and tighter ones. With the crop factor of 1.33 l am guessing that makes the 25mm a 33.25mm. Correct me if l am wrong.
Strait out of the red cams is R3D so the contrast if raw files is whatever you want it to be. It cat be like a blank white page or a checkerboard. You must and can create what you like. Unless you are shooting compressed prores then what you choose is baked in and not just meta data. If you light your scene,set your iris what your shots call for to your plan then use the traffic light system first and iso to make monitoring make sense then l will be perfect. Pretty straightforward road to great footage.
