I currently shoot a lot of Bracketed shots for exposure blending, and with each shot having a different shutter speed the auto-stacking can fail to accurately stack the grouped shots - especially when the shutter speed gets up into 10+ seconds!I would love an option for Auto Stacking to work on the time delay between the shutter closing and the shutter opening again, so it is a true measure of the gap between shots. In this way I can auto-stack on all bracketed shots even when the shutter speed is seconds long. Calculate the time between shots by adding the shutter speed to the capture time of the first shot, and then compare this to the capture time of the next shot, and if I am using Continuous shooting, this gap will be only a fraction of a second, regardless of the shutter speed.Gary
