Using DPP Express (iOS) to convert EOS RP RAW to JPG changes image colours?

Hi all,

After migrating to an EOS RP (CR3 files instead of CR2), I had to update my mobile (iOS) workflow (on iPhone 14 Pro and/or 2021 iPad) to edit my RAW images, and exporting to JPG (as my earlier-used workflow did not support CR3 files).

I'm experiencing some serious issues with this, seeking help.

For example, let's consider the RAW image below (RF 16 mm F2.8), as visualized in iOS Photos after importing it directly from the SD-card:

RAW image, as shown in iOS Photos app (image transferred to iPad or iPhone using SD-card to Lightning reader)
RAW image, as shown in iOS Photos app (image transferred to iPad or iPhone using SD-card to Lightning reader)

This image does not look like the image captured/shown on the camera, at all (it does not contain any (lens/colour) corrections), the iOS app DPP Express (from Canon) is able to show this properly however:

RAW image loaded into DPP Express (iPad, same behaviour on iPhone)
RAW image loaded into DPP Express (iPad, same behaviour on iPhone)

I've tested several other iOS software, such as Pixelmator Photo, Darkroom, Snapseed (doesn't even support CR3 files) and Lightroom, where only the latter also supports lens corrections (the others just show the same image as iOS shows it, without any (lens/colour) correction). Lightroom is however somewhat different from Canon's DPP (regardless of importing with 'Adobe settings' or 'Camera settings'), where I'd like to see the same as captured in-camera, while I also don't really like the high fees associated with Lightroom (I'm just an amateur taking some photos). Hence, I decided going with DPP Express (1€/month).

However, if I export this particular image (now even without any RAW editing) using DPP Express to a JPG file (max. resolution), I'm left with this result:

Exported JPG from DPP Express, lens corrections are applied, yet colours look quite different (more pale)
Exported JPG from DPP Express, lens corrections are applied, yet colours look quite different (more pale)

After some (quite detailed) inspection, I found out that within DPP Express, I am able to also see the colours as they are actually exported to JPG, but only when zooming-in beyond '100%' (which is quite a bit), see below:

Screenshot of RAW image displayed in DPP Express, zoomed to 99%

Screenshot of RAW image displayed in DPP Express, zoomed to 100% (this triggers a detailed rendering, it seems)
Screenshot of RAW image displayed in DPP Express, zoomed to 100% (this triggers a detailed rendering, it seems)

It seems only the colours as they will be exported to JPG are shown when the image is rendered in high detail when zooming-in beyond '100%'. I find this rediculous, as the exposure/saturation corrections that I'd like to apply to my image are image-wide (so I want to see the whole image while editing, not only a tiny detail). Now, after being satisfied with my edits while inspecting the full image, I'm left with a completely different JPG export compared to what is visualized. What?!

Does anyone have experiences with this? Should we avoid DPP Express all together? Any advice on how I should change my mobile workflow? (hopefully without Lightroom)
 
I have experienced the same thing. My exported pictures from DPP Express (on iPhone) look COMPLETELY different from the preview in the App that I have spent a lot of time editing before. This is ridiculous and makes DPP Express unusable, as the result is unpredictable and unsatisfying.

Have you come up with an alternative workflow? I was keen to use Canon's own software, as I find the JPEGs from my Canon G5X Mk2 look pretty good, especially regarding chromatic aberration, but wanted to be able to edit them a bit more before converting to JPEG.

I'm thankful for some tips and advice to be able to edit the shots on the iPhone with no Desktop at hand!
 
Ahh, very annoying indeed, I’ve migrated to a Lightroom-based approach (iOS), while accepting the higher annual fees..
