Purpose Sensitive Stacking [Smarter Auto-Stacking]
Nearly always, the reason I use auto-stacking in LR is because I have several consecutive images that I have bracketed for exposure. Then I have the tedious job of going through all of the stacks to find which ones were actually bracketed for for HDR stacking. It occurs to me that LR could have made this job easier for me and perhaps it has. Maybe there is some way for me to tell LR to do the auto stacking only when the exposure changes between the images. Is there a way to ask for this? LR has all the information available to it as meta-data.
But if there is no way for me to specify such smart stacking, I would ask why not?
