EXIFTOOL , DxO Photolab 5 and Canon SX70 HS
6 months ago
This may have already been discussed in the past (I could not find any close matches), but I found a way of using Canon SX70 HS raw images in the DxO Photolab software to make use of the excellent "DeepPrime" denoiser contained within that program. Canon SX70 HS is not currently supported within DxO Photolab.
DxO Photolab does have support for the previous model - the Canon SX60 HS - and I tried the workaround detailed below. It seems to work well.
I downloaded the completely free standalone "exiftool" program (developed by Phil Harvey), very easy to find on the 'net and download. I downloaded "exiftool-12.45.zip" and unzipped it to a folder on my PC. Then renamed the downloaded file "exiftool(-k).exe" to "exiftool.exe" (as per the installation instructions on phil harvey's exiftool website) and placed it into a folder on my PC.
I then used the following dos command to change the exif value on my SX70 raw files to be the SX60 raw exif value. This just changes the "model" exif value within the metadata. You would substitute "C:\My Pictures" folder with whatever your directory is called. Please ensure that you run this command from within the folder where you have stored "exiftool".
exiftool -model="Canon PowerShot SX60 HS" -ext cr3 "C:\My Pictures"
This just scans all .cr3 images in the specified folder (e.g. "C:\My Pictures" etc) and changes the "model" exif value for all .cr3 files to the SX60.
Then load these .cr3 (raw) files into DxO Photolab 5 and process as you would with other raw files from DxO compatible cameras. You should be prompted by DxO PL to download the SX60 RAW module the first time it encounters an "SX60" raw file.
I always export the files from DxO to the ".tiff" format. If you desire, you can then invoke the command above to change the exif value back to "Canon PowerShot SX70 HS" on your original .cr3 files and also on the new .tiff files. All you need to change in the command line is the model, the extension (.cr3 to .tiff) and the folder name(s) which contains your .cr3 and .tiff images.
I processed about 20 SX70 HS raw files this way and everything worked fine. I realise this is a "cheat" fix, but it does appear to work (in that DeepPrime is used on the SX70 raw files).
NB. By default the exiftool command creates a backup of each image it changes in the same directory. It suffixes "_original" on the backed up file. You can disable this backup by adding "-overwrite_original" on the exiftool command as follows:-
exiftool -model="Canon PowerShot SX60 HS" -ext cr3 "C:\My Pictures"
-overwrite_original
There are more command options on Phil Harvey's exiftool website.
Just thought it may help somebody else with the Canon SX70 and wanting to get the best denoiser working on their raw files.
