Select the photo and choose Photo > Reload from Disk. If your version can decode that raw now, Imago reads the sensor data again and the Preview only notice goes away.
Symptoms
- The Edit panel shows Preview only, with the text "Imago can't decode this raw variant yet" and the name of the variant.
- You updated Imago to a version that supports your camera, and the photo still looks the same.
Fix
- In the grid, select the photos that show Preview only.
- Choose Photo > Reload from Disk. The right-click menu on a photo has the same entry.
- Open a photo again. If Preview only is gone, the photo is now decoded from the raw data.
If Preview only stays, your version still cannot decode that raw variant. Update to the latest release and try again, or report the file as described in Get help with a problem.
Why this happens
When Imago cannot decode a raw on import, it remembers that and shows the camera's embedded JPEG. It does not check again after an update on its own. Reload from Disk is the way to make it check. Compressed Olympus raws, some Canon CR3 variants and Nikon High Efficiency NEF files are examples of files that use the embedded preview.
0.7.1 decodes Canon EOS R5 Mark II C-RAW files that earlier versions opened as Preview only. Photos imported before switch over after Reload from Disk.
Photos shown from the preview keep the camera's picture style and white balance, because they are the camera's own JPEG.
