I settled on Pixelmator Photo to do my on-the-go processing of RAW files while I was on holiday recently. It was a great experience except for two missing features.
First, and I’ve read this is coming, is a vignette tool. Second, most importantly, is noise reduction. If I’d had those two things, PP would have been a one stop shop for camera-to-web workflow entirely on my iPad. I ended up sending on to Affinity Photo for those two treatments when needed, but that app is way overkill (and not as convenient) for just smartening up images for publication.
Discuss Pixelmator Photo and photo editing on iPad.
Thanks for the feedback — as you've read, a vignette adjustment/effect is in development, as is a noise reduction feature. We're still working on both, though, so the next few updates will include some other improvements and new features. But if everything goes well, these two should be available in the not too distant future.
These two and a clarity filter would make it complete for me. Loving the share sheet option in the latest beta.
