I think I bit off more than I can chew.
Last night for the moon rise, I set up my camera to take 3 exposures at +/- 1 stop every 30 seconds. Then I was going to merge each set and make a video of them.
I now have 900 images so I would need to merge 300 sets. That might take me the rest of my life Is there a way to program Lightroom to merge 3, then move to the next 3 and merge them, rinse and repeat?
I know that Photoshop is programmable. I did it way back in the dark ages before LR but I haven't done it since but would need to research how to do that so I thought I'd ask here about LR first.

I think the best you can do in LR is to select 3, control-shift-h, which puts it in the queue to merge without bringing up the dialog box, then move to the next 3 and do the same thing. I'm not sure how many of those it will let you queue up, but it will work though two at a time from the queue.

Otherwise, I think you have to go with the more powerful scripting in Photoshop.

1. Select all the photos and do Photo > Stacking > Auto-Stack By Capture Time. That will put each group of three brackets into their own stack.

2. Do Photo > Stacking > Collapse All Stacks to ensure all the stacks are collapsed.

3. Select all the collapsed stacks and do Photo > Photo Merge > HDR. This will enqueue merges of the photos of each of the stacks, using the last-used HDR settings.

That was quicker than trying to write a program. My queue is now 253 items. Took about a half hour to queue all of them up once I got into a groove.

Thank you!

I didn't see this in time. But I'm going to try it out next time. Wow!

Glad I could help. And just noticed you are "just around the corner" from me, in a Texas sort of way. I'm actually on the west side of Round Rock.
