I used the ProPhoto profile instead of the sRGB profile for the TIFF exports. The result in (2) is not using exactly the working steps described above. Usually the colors are more off because of many reasons: The Color-checker is not receiving the light evenly, mixed light temperatures, reflections by nearby objects etc. Then balanced again and overlaid with the reference ColorChecker patches.

The brackets were balanced to the grey patch in Adobe LightRoom (LR), exported as 16-Bit TIFF images (ProPhoto profile instead of sRGB), stitched in PTGui and loaded into Nuke as a EXR with the colorspace linear – ProPhoto. (2) This is a crop from LR-ProPhoto PTGui. And the patches are overplayed with the reference ColorChecker patches. The photo is converted from Canon RAW to ACEScg with Affinity Photo (White Balance with an averaged sample area). (1) This is one single exposure photo from the bracketed images that made the 360° panorama.
On some colors you need to look twice to see the square shaped reference color patches overlaying the photo (1).Īnd then there is is best result I got from finish stitched HDRI with PTGui (2). Examining the RAW brackets and the resultįirst I checked only one RAW bracket in Affinity Photo. Balanced Canon 5D 360° HDRI with color chart. The workflow that we use is based on a lot of tests that were done by Sönke Heuer from INFECTED.DIGITAL. White Balance again the “linear-sRGB” EXR file to the 18% grey patch in Nuke.

Stitch all TIFF bracket in PTGui Pro to a OpenEXR file.Canon RAW images – white balance in Lightroom.This HDRI is made of 7 RAW brackets and 7 directions with a 8mm fisheye with a Canon 5D. Years later I felt it was the time to dig them up again and share the results of these tests.Ĭanon 5D 360° HDRI from a production in Los Angeles In the end we used the established workflow for the job and all the test results were wasting even more space on my hard-drives. Can’t I just use PTGui to convert directly from RAW brackets to a 360° panorama in EXR format? Does it matter if I don’t use Lightroom and use other raw development tools instead? If I need to convert to TIFF first, which colorspace should the files be exported in? This process is time consuming and wastes a lot of space on the server. We have an established workflow to convert the RAW brackets with Lightroom to TIFF images and the stitch the 360° panoramas with PTGui Pro. In late 2017 I was involved in the preparation for an upcoming job for which we needed some 360° HDRIs to light some scenes in Maya.
