Batch processing can mean multiple things.
What specifically are you looking to do?
Basically, I have 80 pictures that I shot in HDR mode (so 240 in total). So every 3 pictures I'm merging into 1. I'm finding that I have to highlight every 3 and perform the merge function one by one. Just seems like wasted time. So I'm wondering if there is a faster way. Thank you.
Not that I'm aware of.
No, there is no way to tell Lightroom "for the next 240 images, group them by three, then send each group to HDR merge".
You need to do the grouping and sending to HDR merge manually.
However, if I remember correctly (not a safe bet), you can start the next group processing before the previous one finishes.
How well that actually works will depend on the CPU and memory of your computer.
Right, that's what I've been doing. Thanks for the reply.
In the current version you can group bracketed exposures to staples (by time) and then you can mark all staples and press STRG+SHIFT+H to run the basic hdr merge with the setting of the last merge you did (merge > HDR).
