Affinity Photo/Designer, LumaFusion, and Ferrite are all full blown professional caliber editing programs available on iPad, and full blown Photoshop is, or will be, available as well. I use all those apps and others to do “Pro” editing. I don’t think it’s fair to just ignore those types of iPad apps—they are not mobile versions of more powerful software but rather full blown editing software. I imagine Final Cut and Logic Pro will also eventually make their way to iPad.
Many of you saying “No, because it can’t do this” are either being willfully ignorant of the available software in order to prove your point, or just still not aware of what the iPad can actually do.
I've used Affinity & Lightroom on the iPad Pro for RAW photo processing but have found it just too inefficient for working with large numbers of images to process - >>100. I find it much better/preferable to working with a machine with a larger monitor/display, full mouse support with a real pointer, full-up Lightroom, and other s/w with extensive DAM support for files spread over multiple storage locations. On a recent 3-week trip I took both for comparison but quickly ended up just using the laptop. I'll stick with the laptop (and home desktop) for now and I don't anticipate changing with iPadOS.
