Okay, just imported an SD card of RAW wedding photos onto my iPad Pro and really disppointed in availability of good editing apps. Snapseed appears to be the only real option for full support. Pixelmator only loads up the preview image and not the full size image. Google photos loads up the full size image and lets you edit it but when saving, it only seems to save an edited version of the jpg preview so you get a heavily pixelated normal sized image. The alternative is to edit in Photos and then use extensions or do a minor edit in Photos and save to get a jpg and then open this up in other apps. Ca ayone recommend a good editing app with full RAW support? The abandoned Photogene⁴ app works well but not sure for how much longer.
