Does anyone use DPP4? What do you think? I am having issues with it and have emailed Canon and waiting for a response. I have been trying to print tiff files on my Pixma Pro 10 and whenever I select one and go to print it sends me to Print Studio Pro to fine tune and select ICC profiles etc. The problem is when PSP appears there is no image in the print box to print. Also occasionally tiff files do not show in the image gallery. Just wondered if anyone has had problems and if solved I would be very interested to hear. However If I use Adobe Lightroom CC or Photoshop I have no problems. I just want to keep my workflow all Canon if I can. I am running a Mac with OS Monterey. I also have a Canon TS 5050 printer and same applies.
