So, I'm trying Depth Compositing for the first time and running into some frustration.
I am using an RP with the 24-105 lens, both are compatible with focus stacking. I have DPP 4.13.10.
I have enabled focus bracketing and created a separate folder in camera. I take the shot and the RP takes 20 photos with different focus, as I've set it to do. I am shooting .jpg in medium size.
The images open in DPP 4. I have tried both clicking on one image, and selecting all images in the range. Either way, I start the Depth Compositing tool and it begins to run. However, it gives me an error message for each image and no compositing occurs.
I am experiencing the same problem. I talked to someone in canon technical support yesterday but he was not able to duplicate the problem. I used depth compositing a couple of months ago and everything worked fine. Since I had updated Digital Photo Professional to 4.13, i tried installing an earlier version but still ran into problems. I uninstalled DDP4 and reinstalled the new version and am having the same problem.
I may have a solution for you. I've spent the last day trying to resolve the same problem with my Canon M 6 Mark ii which has similar Focus Bracketing capabilities. I could not get the latest DPP4 Depth Compositing software to work on my photo set taken with an EF 100mm f2.8L MACRO IS USM lens, which is specifically approved for this application in the DPP4 Instruction Manual, BUT which needs to be attached to the camera with an EF-EOS M mount adaptor. (I used the Canon mount adaptaor which came with my kit.) I tried different file types, focus types, everything mentioned here and everything I could think of. FINALLY, I switched to my EF-M 18-150 lens, turned it to 100 mm and took the same subject with the same settings and focus bracketing settings. IT WORKED! The DPP4 Depth Compositing software was able to compile the photo. I can't say for certain that the problem is use of the adaptor though I suspect it is. However, my 100mm MACRO lens is at least 10 years old, so even though it has the same name as the current versions, it may not have the same electronic capabilities. So, I would suggest trying a lens that is native to your camera.
