Multiple exposures combine from two to ten separate exposures in a single shot. The
results vary with the overlay mode.
Add
The exposures
are overlaid without modification; gain is not adjusted.
Average
Before the exposures are overlaid, the gain for each is divided by the total number
of exposures taken (gain for each exposure is set to 1/2 for 2 exposures, 1/3 for
3 exposures, etc).
Lighten
The camera compares the
pixels in each exposure and uses only the brightest.
Darken
The camera compares the pixels in each exposure and uses only the darkest.
