All iPads RAW/JPEG photo quality visually reduced once saved on Ipad Air

[pharaon78]

Hi All, I am a professional photographer that got a new Ipad Air (3) to export and edit my photos.
After transferring photos into my ipad, I used different apps (lightroom, darkroom etc.) to edit 24MP RAW photos. When I view the photos in these app’s library, the quality is great; once zoom in still a lot of sharp details. Once i save the file as JPEG [100% quality], depending where i view this photo, quality changes a lot. If i view in Lightroom or Apple Photos app, the quality seems very good. If i copy or exoort this photo into other folder (on my ipad or icloud) or if i share via wetransfer for instance, the quality is highly lost. The photo dimensions info is still 6000x4000 but visually there is a big sharpness deterioration (more obvious once zoomed in). I am completely puzzled how to share the photos with my client with full quality preserved. Anyone has any idea why this happenning and how i can find a solution? Thanks

Depending on how the picture is exported, or shared, images sometimes get recompressed. If i share an image to, let's say, one drive, pictures typically get recommpressed if i share from the photos app. But if i import from one drive itself, no compression. Many apps also import a recompressed image depending on the needs of the app, like facebook. I think snapseed imports a copy of images, but dont know if it is recompresed because the import file name is random. Apple devices do a lot of image conversions in the background to make images compatible with a wide set of devices and apps. Probably what your seeing as less than sharp detail up close, is color subsampling. A 100% jpeg uses 100% color resolution, but when converted again, the color resolution is only 1/4 of resolution of the brightness. In fact most jpegs out there are like that. Even DVDs. Blueray, ect. Our eyes are not great at color detail vs brightness.
Also see what color space you are using? Since you are using raw, you can set the color space. If you import as AdobeRGB, the colors may look washed out on an email or some web browsers, like chrome, which deal only in sRGB. If you take the wider color scale of Adobe RGB and read it as sRGB values, which what happens in some apps and websites, the pictures colors wash out.

If your client have an Apple product, via AirDrop is the best option to share the photos. If not, you can use Google Drive.

Ps: a new iPad Air is coming next week 😬

@lostless When it comes to exporting/saving the image (with fine details and colors) from the photo editing app to any folder in ipad, I don't really have a choice. All I can do is the export with the highest possible quality which doesn't end well. Regarding the colorsubsambling, I cannot really tell the difference between original and compressed photos until I zoom in; once zoomed the resolution is clearly lower, photo becomes blurry. So rather than the colors, the issue is details and resolution.
I find it outrageous If we are given no chance other than compressing photos when exporting from Photo editing apps; even professional ones like Lightroom etc.
I really hope to find someone on the forums who found a solution to this.

@Marlon DLTH :) @AutomaticApple I got it in July and back then the rumors were still showing a launch in 2021. As there is always something new coming up, I didn't wait for an undetermined period of time But I think my issue is nothing specific to Ipad Air 3, as far as I saw on forums all iPad's are driving the photographers mad. I wouldn't buy it if I knew...

Oh ok, I thought you bought it a few days ago.

I hope you find a solution!

Yeah, maybe every few years or so. 😆

after doing a little experiment on my iPad. I took a raw image, rendered it to a 100% jpeg to photos app. Then I exported to files. I noticed the lack of detail that you are talking about in the files app using iCloud. All the grain and sharpness smuged out. So I reimported that file back to photos. Detail comes back. There never was any loss. I think the rendering engine of some Apps shows a lower resolution temp file for viewing. try Exporting back to photos or Lightroom and see if the detail are still there. There may be no loss at all.

I just did a test, exporting a JPEG processed from a Canon RAW image in Lightroom through the Files app to my laptop (SMB connection). Looking at the enlarged image on a 4K monitor connected to the laptop, I don't see any degradation in detail.
