I'm a hobbyist photographer, and I do the vast majority of my photography work on a 9.7" iPad pro, with a Pencil. I'm constantly editing 24mp RAW files in Affinity Photo, which is about as close to full-fat Photoshop running on the iPad as you can possibly get, and let me tell you: It's fantastic.
I turn on my camera, I shoot some images. I open up Cascable, which connects to my camera's wifi, and I pull down some images. I flip through them and find one I like, the one I want to edit, so I click on that one and click "share", and then select Affinity Photo.
Affinity Photo opens. It's 95% of the power of desktop photoshop, albeit organised in subtly different ways. I do the things I would normally do: White balance, HSL, blemish touchup and even frequency separation. I click export, and save to camera roll.
It's in the camera roll, and I select it, and I share it over email to some friends, and to discord, and to instagram.
I don't get where the problem is.
Copying an edited photo (or drawing in my case) to a flash drive involves an external computer. It's not that it's impossible it*s needlessly complicated and clunky. I don't ant to try hard enough, I want the device to make my work easier.
I would like the touchscreen paradigm to be expanded. Pencil, force touch, and perhaps something like Kinect/Soli:
Isn't that the paradigm we're currently in? Local file management is terrible on iOS. For professional photography (one the markets that Photoshop targets) cloud storage is not up to the task. The raw files from my work camera are 85MB each. I average about 1500 shots per shoot. That's a lot of time waiting for files to upload.
Personally I'm imagining a future where my files are not in the hands of the surveillance capitalists.
