Lemon Tree Posted December 22, 2022 Share Posted December 22, 2022 When editing the metadata of an existing 16 bit, zip-compressed, little-endian TIFF file, it takes roughly 5 to 10 seconds to echo each keystroke. This was observed for the keywords and description fields. It does not occur for a newly created file. The TIFF was produced using Capture One 22. Latest 2.0.3 version, macOS 13.1, Intel, plenty of memory. (Also occurred on 2.0.0.) Affinity Photo 1 can perform the same edits with no lag. I can supply a sample file if necessary, but don’t want to attach it here for unrestricted public download. Quote Link to comment Share on other sites More sharing options...

Lemon Tree Posted January 4, 2023 Author Share Posted January 4, 2023 I’ve worked out what it is about that particular TIFF which causes a problem. It has, as its embedded profile, a camera profile generated using Lumariver Profile Designer, for use with Capture One. This is probably a very strange profile indeed! I regenerated a similar TIFF from the same raw file, this time using the Prophoto RGB profile as is my usual practice, and the problem goes away. I verified again using the version with the camera profile that the problem still happens, so nothing on my system has caused it to go away. (Capture One calls Prophoto RGB “ROMM RGB”.) As the camera profile was used in error, and my practice is to use Prophoto RGB, this bug no longer affects me. The original TIFF with the camera profile was uploaded the next UK business day after being requested. I can supply the RGB ROMM version I used for the A–B test, but the engineers can probably extract the camera profile for their own A–B test using exiftool or a similar tool.
