As important as post color correction might be - the mood and look created by on-set lighting can never be substantially changed or altered in post-production. In other words: To enhance and create a look afterwards all the information must be there in the camera material for the colorist to work with.
It's a cinematographer's job to ensure exactly that and to keep in mind the possibilities of analog and digital post production to ultimately help the story and assist the director in creating his vision.
Helping the director archieving his goals in terms of blocking and choice of camera-angles- and movements is also part of the cinematographer's job description.
I have shot countless pieces ranging from commercials to short films on a wide variety of media, such as DV, DVCam, Digital Betacam, HDCamSR, DVCPro, DVCPro HD, 16mm and 35mm film both with spherical and anamorphic lenses.
My experience alows me to, regardless of the format, archieve the desired effect, look and mood.
