Flash Delay
When you use one of the multi-exposure modes, FlexColor will instruct
the camera back to make the captures as quickly as possible, allowing time
for the image data to download after each capture. If your flash system
requires extra time beyond this to be ready to flash again, then enter the
required minimum charge time (in seconds) in the Flash delay field.
Process and store full image when saving
Check this if you want to avoid updating the 3f files with the processed
info when saving from these. In this case processing will only be done for
the actual cropped area and your unprocessed 3f file will stay small and
unprocessed.
