P: Ability to batch process Photo Merge (HDR and panorama)

This better HDR batch handling is good, but please create way to add directly many stacks to HDR batch.

I was hoping for an HDR batch feature in new Lightroom Classic but again I'm disappointed 😞
Doing a lot of HDR images is a painful procedure - pressing ctrl-shift-H a hundred of times is annoying. 

Is this really so difficult to realize? "Open folder "xyz", take the first 3 images - merge them to HDR - take the next 3 images ...

"It still means having to possibly press ctrl+shift + H one thousand times. "

Right -- I filed a bug report on that (see above).  Maybe they'll fix it in LR Classic 8 :-<

It still means having to possibly press ctrl+shif+ H one thousand times. But theoretically it won't crash or slow down because of the simultaneous jobs.  The AutoHotKey may actually work now without the lag and having to put in an exponential delay in the script.  But I switched to SNS-HDR for my merge a while ago because it has a good batch function and gives much better results than Lightroom.  I think the cost for SNS-HDR was low compared to what you get.

I filed this bug report on the internal error when trying to initiate multiple merges simultaneously: https://feedback.photoshop.com/photoshop_family/topics/lightroom-internal-error-when-initiating-mult...  Please add your me-too vote and detailed opinion.

I noticed this as well. It would be nice if there was a setting for us to set how many merge operations we would like to perform at once. I don't mind doing headless merges for now but if we could at least set it to do x amount at a time it would be a big step in the right direction.

This is now implemented in LR 7.  According to Lightroom Queen Victoria Bampton,  "Multiple merge operations are now added to a job queue behind the scenes to avoid impacting UI responsiveness."  

This lets you initiate many merges -- dozens or hundreds -- and LR will process them one at a time.   LR will show you the progress of the merges when you click the progress bar in the upper left corner:



To prepare a large batch of merges using the last-used merge settings:

1. Stack each set of photos to be merged.

2. Do Photo > Stacking > Collapse All Stacks.

3. Select each stack in turn and do Shift + Ctrl + H ("headless merge").

Unfortunately, you can't select all of the stacks and do Shift + Ctrl + H -- LR gives "An internal error has occurred".    You have to select each in turn and start the merge.  

Sigh, it seems like whoever designed this improvement didn't stop to actually think how it might be used. But overall, it's a considerable improvement for doing large batches of merges.

I have recently purchased AuroraHDR 2018. The latest version works on Windows. The MAC version already supports batch processing and the software vendor has promised batch processing on Windows by the end of the year. The results are really quite good and the software works well with presets. It also has detailed controls for photographers that like to drill down into the advanced settings.

photomatix bites. I've used it before... LR results are so much more realistic. LR just needs to do a bit more with helping punch out the windows. The exposure is there and I shouldn't have to paint it out... I'd like that before batching, TBH.

Real estate photographer here. Please bring batch processing to Lightroom! I'm not thrilled with using Photomatix.. I wish I could just stay in LR for the entire workflow.
