Title: Canon dr4 file with HDR PQ enabled
Post by: JohnMoyer on March 03, 2024, 02:29:50 PM

In Canon DPP software I enable HDR PQ and save recipe to dr4 file. I do not know where to start on this.

exiftool -G0:2 -s -U -a -v2 IMG_9159hif.dr4 
  ExifToolVersion = 12.77
  FileName = IMG_9159hif.dr4
  Directory = .
  FileSize = 9134
  FileModifyDate = 1709480963
  FileAccessDate = 1709493377
  FileInodeChangeDate = 1709480963
  FilePermissions = 33188
  FileType = TIFF
  FileTypeExtension = TIF
  MIMEType = image/tiff
  ExifByteOrder = II
  | Warning = Bad IFD0 directory

Editing change to HIF compared to JPEG was to brighten 2/3 EV to take advantage of the additional 2 bits. HDR PQ mode disables some editing menu items.

Thanks for this report and for the samples.

It may take me a few days to look into this.
