Question

Colour space shift on PNG export from iOS Photoshop

I'm getting colour space shifting when I export a PNG with or without transparency from Photo iOS. Attached are a couple of photos...one exported as a jpeg - it has normal/expected colours. The other was exported as a PNG...massive colour shift. Any ideas what is causing this?

That should read 'Photoshop iOS'.

This looks like an image in the ProPhoto color space that has been exported without checking Convert to sRGB and Embed profile, and then opened in a web browser.

Web browsers will assign the sRGB profile to untagged images (that don't have an embedded profile), and since the image was created in ProPhoto, sRGB is the wrong profile, and the colors wiil be muted.

When I open the image in Photoshop and assign the ProPhoto profile, it displays correctly.

Always check Convert to sRGB and Embed profile when exporting.

    I don't use an iPad, so I can't help you with the export options, I use Lightroom Classic and Photoshop on Windows.

    In Lightroom Classic there's an option in Preferences > External editing for what color space to use when editing in Photoshop, and the default is ProPhoto. (I have it set to Adobe RGB)

    Is there a similar option on the iPad? If there are no options for converting to sRGB and embedding the profile when exporting. I would set this option to sRGB.

     

    The image with the muted colors is almost certainly created in ProPhoto – when I assigned ProPhoto in Photoshop, it displayed exactly the same as the other image you posted.

    Also BTW, both images that you posted are jpgs, not PNGs.

     

    To establish what color space an image has in Photoshop, click the little arrow bottom left on the taskbar status bar, and choose Document Profile.

     


    Thanks. I was looking for input from iOS Photoshop users on this one. I posted jpegs to illustrate the problem. I am about 30 years in on desktop Photoshop, but today I wanted to see how workflow would be strictly using the iPad. I appreciate your input.
