>>3277553Expose for a shot and then divide the exposure settings by the number of exposures. For example, you want two shots, you meter the scene at 1/500 @ f5.6 for ISO 200. For two exposures on the same frame you would go for either 1/1000 @ f5.6 or 1/500 @ f8.
The easiest way is to just double the ISO value and expose both shots for that instead of your actual one.
Mind you this doesn't account for dark/bright areas which would be more/less prominent so it's a bit of a trial and error thing when overlapping shots.
The usual is bright background with dark figure in the middle (portrait etc.)
This one's a cool double exposure I found and I want to try myself, covering half the frame and exposing each side correctly.
