Focus Stacking Problem with Canon CR2 Files

[jimgott26]

Congratulations on what will inevitably be a great product.

 

I ran into a couple of problems today.

 

1) LR to Affinity Photo transfer via Edit In preference is not working. This was documented by another user so I won't beat a dead horse, but this is why I chose to attempt Focus Stacking external to LR (Item 2 below).

 

2) Ran Affinity Photo in stand-alone mode. Wanted to pull in 23 Canon CR2 photos taken at various focus points. Camera is a Canon 6d with a Canon 100 mm f2.8 macro lens attached, tripod mounted. Settings were ISO 50, f4.0, and shutter at 1/30 second.  Attempted this using the New Focus Merge option. The drop down box indicates a CR2 file is an acceptable input. This method failed with a sequence of "source images" all displayed as bleached out photos with each histogram showing content highly concentrated to the right. The resulting stacked photo also appeared the same way.

 

I then decided to manually convert the CR2's to JPEG's and try again. Success this time. Execution was fast and the result was beautiful. I also have Helicon Focus but did not compare the execution times, but they are probably close. Unfortunately, HF will accept CR2's as input.

 

Request that you investigate and correct. Thanks very much.

Hi Jim

 

Focus merging is meant to work with RAW files and did last time I tried. Any chance you could let us have the source CR2 files via Dropbox?

 

Thank you

I have the same problem with my Canon 70D RAW files. I posted below in new topic. I'm including here to put the problem in one thread... you can delete the other thread if you want to.

 

I have been trying a number of different features of Affinity Photo, and while much of its capability is commendable, the focus merge feature seems to be washing out the final photo to the point that it is unusable when I use the Canon RAW files from an EOS 70D. It seems to work OK when the RAW files are converted to jpegs, although by starting with jpegs I don't have enough dynamic range to do many adjustments. For some reason the board is not letting me upload the final result. My original RAW files are too big to upload.
