I've shot a 5 gigapixel 360 degree panorama, totaling around 1400 shots in a -1.3-0-+1.3 bracket, and I'm trying to stitch it and tone map it. So far I've managed to decently assembled the panorama in Autopano Giga and render it a few times, but I'm unable to tonemap the resulting image. I'd rather not tonemap before stitching as this has the potential to create uneven exposures, particularly across a 360 degree panorama.
Steps I've tried:
- Exporting a .psb with layers - Photoshop's tone mapping won't deal with this
- Exporting a .hdr and tonemapping with Photomatix - Photomatix tries to save the .tiff as but this results in a file over the 4gb limit which is corrupt
- Exporting individual .tiff files and merging with Photomatix - Photomatix crashes immediately after (apparently) finishing the merge to HDR.
Note that I have Photoshop, Autopano Giga and Photomatix Pro available currently, and possibly more from my university. I'm a fan of Photomatix's control and the resulting images but it seems unable to handle such large images.
What software would appropriate for tonemapping an image this large?
