This conversation has been merged. Please reference the main conversation: Lightroom: Better auto stacking for bracketing,HDR, and panoramas

LR needs to get smart. With a single command, LR could look at photo times and stack HDR and panos. It could then do feature recognition to determine if a shot has overlap [HDR] or if it's panning [Panoramic]. Done. Let me drink my coffee, come back and deliver my photography.

Indeed. See autopano from kolor for automatic bracketing identification and automatic panorama identification.
Unfortunately existing auto stack by capture time, doesn't seem to be able to use sub second information, so when I shoot a bracketed panorama (moving fast) it thinks some stacks have 4 some have 2, some have 16.

yes left to right then right to left. but in my experience, it works for like 3/4s of the stacks and it can be .9sec
(when one stack finishes at say 1.1s and next one starts at 1.9s if they are using interval and next just delta of capture time which I really think they are doing but without data I realize I'm being the unhelpful internet)

I'm the last person that will say that LR works predictably. I'm Mr. RewriteLR guy

For the record, my suggestion to LR would include analyzing the optical flow between shots to determine a pano so in your case, LR would see L->R pan [feature X moved from r to l] in the first 3 and R->L pan in the last 3. So maybe we could just kill the whole time interval dependency altogether.

totally agree. sorry to sidetrack the thread. my workaround workflow is to open the folder in autopano using browse folder, it auto finds the brackets and treats them as a single set, and using time intervals divides the folder up in to groups (works great to set at 20 seconds for me) and then within a group analyzes overlap and figures out which are in a pano. I then do "extended save as" which moves all the pictures in the panorama in to a subfolder, I then go back to light room and tell it find missing files and point it to images in subfolder.

It's a worthy conversation. If they implemented something like this, it could free up 10-20 hours a month of my work spent finding, selecting, commanding pano merge and HDR merge. I do a ton of HDR work professionally.

well I guilted myself in to collecting data rather than real work (ok I was already procrastign commenting here)

 lightroom only shows the seconds in capture time (see here where they say they use difference in capture time https://helpx.adobe.com/lightroom/help/grouping-photos-stacks.html#WS4FA9631A-25CC-43e2-B3E2-20FC80E... )
on a landscape panorama where I wasn't in a hurry because nothing was moving (where I was shooting 0, -2, +2) on a 5ds r with a slow buffer

autostack group 1
1 - 3:14:47
2 - 3:14:47
3 - :47
4 - :48
5 - :48
6 - :49
7 - :50
8 - :50
9 - :50

all of these exposure speeds were ~1/100th of second so provides no data on whether these use start or stop (and if they don't have access to sub second timing, then irrelevant)

I guess the fundamental issue is that I wish this set was bracketed by 3, so I could see the panorama in the grid, rather than being grouped in to sub batches. If I increase the interval to more than 1 second, say 10 seconds, since it's processing the entire folder, i starts to combine non bracketed pictures that aren't panoramas together.

The time taken to try different settings, and then get close then check and unstack (and change the stack if one is put in the wrong group) seems to add up to more than the time savings for me.

If I could select a group of images (without moving them to another folder) and run autostack on the selection, that would help some https://feedback.photoshop.com/photoshop_family/topics/lightroom_auto_stack_by_capture_time_use_curr...

also if they don't want to implement algorithm to try and figure out bracketing sequence (say 0, -, +, vs, -,0,+) ability to select a group of images and stack in groups of n

I was just thinking of this idea a few days ago as a way to remove grunt work. I'm in favor.
