Big panoramas in Lightroom

[8bit]

I have been experimenting with the Brenizer Method and ended up shooting a couple of very large (around 70 shot) panoramas. My PC (Windows 10, Intel i7 6700K, 16GB RAM) seems to be able to handle up to about 32 shot panoramas OK but Lightroom often fails on the bigger ones because it runs out of memory.

If I stitch these into sections of, say, 20 shots or so at a time, can I then stitch these together to make the final image? Will that require less CPU and memory to process than just selecting all images and attempting to do it as one operation?

Have you tried reducing the size of the individual pictures before stitching? How big a file do you need to end up with?

Try using MS ICE, it's optimised just for stitching panoramas.

Lightroom stitch works on raw afik, you can probably export tiff or jpg at lower resolution then stitch those for a smaller overall stitch

IMo lightroom stitching really suffers over about 8 files (6d raw).

If you have photoshop / camera raw it works better, otherwise try ICE or hugin

AFAIK Lightroom can only resize an image on export, is that right? I'd rather keep the images in RAW format as I won't be developing them until they're stitched.

I tried that recently when I was struggling a bit with certain panoramas in Lightroom and it was telling me it couldn't join them together. ICE did but made a mess of it so I gave up. I have tried PTGui as well.

Thanks, never heard of hugin, will look it up.
