You probably know what I mean by “moments frozen in time;” sometimes even done literally (or at least in slow-motion) by cinematographers. Camera operators will often use an intense visual focus, besides time cropping, to enhance the importance in a certain scene with spatial denotation.
Many parts of post-production are related to aspects of cinematography. I think one of the most interesting parts about post-production, as related to cinematography, is contrast. I well understand that it looks, well, stupid, to apply contrast adjustments senselessly. I think physical lighting is the best way to add real contrast. I often find that authors actually — in the case of very profound or important scenes — artificially decrease the contrast, and sometimes use tone-targeted color balancing.
