Often times one might want a portion of the frame to be very dark (an example might be a horror night scene). However, in my experience, when I do not light a portion of the frame and leave it dark the image gets grainy. How to I atchieve this without getting grain in the shot. Do I light it all and iris down. A little help would be appreciated.
The trick lies in the use of edge light on your subject and judicious textural lighting of your background. You need to provide highly selective visual information while keeping light off the subject that you want dark.
Do dark areas get noisy or grainy? Is this fixed in post? My question is about the dark portion of the frame, it seems even the best cameras need light to produce a solid image. I am using a Sony F350 if that helps.
Mike, the subjects of night scenes are usually lit and manual settings of the camera set for the lit areas of the frame. Zoom in on the subject, put the cam on auto, then lock down those setting by switching to manual. See what you think of these settings and adjust from there. If there are dark portions of the frame and the cam is left on auto it might be over compensating thus creating the grainy image. If this is not the case and you are manually setting everything then I'd guess you need more light on the subject. Do a search for
