Default Re: Exposure expert needed!! Damn mrPhotographic Exposure

sunny 16 is just a rule of thumb to get an approximation of a good exposure without having to sit and fiddle and test for ages.

if you want to understand how ISO, SS and f/stop balance and affect each other then i'd do it on a camera, not in MR exposure control.

there are no 'rules' for night shots, only desired setups.

lower the ISO the less grain, but the longer it will take to expose.
higher the f/stop the less depth of field. ie. f/22 keeps everything pin sharp - usually a good bet.
quicker shutter speed for less motion blur.

what would i do for a night shot at night? low ISO, say 50 or 100 to reduce grain. f/22 for sharpness, and set the shutter speed to whatever will expose that iso and f/stop correctly. thats simple 'aperture priority' exposure, where your desire for sharpness (high f/stop) dictates your shutter speed.
but thats a camera.. MR is simply the eV value that exposes it correctly.
