Multiple exposures in-camera: how to get long-exposure effects in bright light
Adjusting exposure for perfect results
Individual frames will need exposure adjustments to get the correct result
With multiple exposures, each frame adds to the exposure. We’ve shot ten frames, so in theory each one should have been taken at one-tenth of the correct exposure so that they all add up to the right value. However, the Image overlay tool lets us adjust the exposure levels as we combine shots. The default strength for each image is 1.0x, but we can reduce this to 0.1x.
The first two frames
For the first two frames, set the exposure level to 0.1x for both Image 1 and Image 2. When you save this merged image it’s going to have 0.2x the final level needed.
Adding more frames
When you open the merged image again as Image 1, leave it at the default 1.0x exposure, but set the new image to 0.1x before you merge it. So now keep on doing this – leave the merged image at full strength when you open it and only reduce the exposure for the new ones as you add them.
