Lightroom Classic: Stack based on content

Hi,

I really like the stacks in LR, very useful for panoramas, HDR or series of shots. Automatically stacking images based on time is already a good feature, but not always very reliable and without a live preview , it can be ... erratic. [Edit: just discovered the preview...]

Now that LR has some AI (Sensei), and anno 2019 (!) I would suggest a stacking option based on content. This way, it would be much easier to stack images for HDR or even multiple instances of the same image. There are many cases where the same scene is shot multiple times, being portraits, wildlife, landscapes.

(By the way, a sharpness assessment tool would also be welcome!)

I agree, but "content" should include EXIF data; images captured at different locations should not be stacked but pictures taken at the same location but different exposures should be.  Perhaps there should be an "autostack for HDR" option as well as an "autostack for panorama" and "autostack for focus stacking" options.

You could also add a specific number for the stack, instead of the time interval between images. This would make more sense for someone shooting in bracketing mode and knowing how many images are in the stack (3,5,7, ...)

Also, take into account the “burst” information from the camera.

All they really need to do is add stacking to the SDK (without import). Various plugin authors could then try to implement whatever stacking patterns people can imagine.

With all the advances that Adobe has put into LR, I am surprised that they have not created an intelligent auto stack for at least HDR images.  In the simplest implementation, LR would look at a series of adjacent images (based upon time, file name) and see if they differ by a constant EV amount (generally change in shutter speed).   Then it would do a quick alignment to check if they could be possibly a set of HDR images.  I think Aurora HDR does something similar to this.

Pans and focus stacked images would require more horsepower (perhaps a batch run over night) to check for auto alignment.

at first it would be good if LR could create suggested stacks of images for HDR, Pan, HDR/Pans or focus stacks (I would pick which I want it to scan for).  In the future as the method is more solid, LR could do the merge for me automatically and create final DNG file.
