Today I realized that photos on Nextcloud uploaded from my iPhone are worse on quality than on iPhone. I’m using jpeg compatibility mode because I use Linux and can’t see heic formats easily.
Is there a way to upload photos with full quality?
This is interesting question. It’s been discussed earlier, but I can’t remember if there was a solution.
How clearly you can see that it’s worse quality?
Hi, is this happening when you compare the photos on your phone’s gallery vs in the nextcloud app?
What happens if you select “Download the image in full resolution” for the photo?
I found that the “preview” that the app is giving me has usually lower detail, which would be ok, but the colors are way off. Once I download the full res image the colors just pop out right away.
I am wondering if there is a way to force the server to not server these “large” previews to the iOS app.
Let me clarify - when I am on the Media tab, I see all the photos (these are thumb-sized previews).
When I tap on a photo, I get a full-screen image, but this one still is just a preview that was generated by nextcloud, only when I download the full-res image, I get the original quality.
I understand this makes sense to save bandwidth etc…however in my use case (@home on wifi) I would rather get original image after tapping on the photo.
One way I can really tell this that image recompression is happening is that I shoot in ProRaw (DNG). The backed-up file through the nextcloud iOS app is clearly a JPEG, is like ~1MB, rather than a ~15MB DNG that I get by copying directly via USB to a computer. I have photos turned off on iCloud.
There are some other subtle differences between JPEG files transferred over USB vs. nextcloud backup, such as different colorspaces.
