Hot tip: Affinity Photo iOS is still on sale for $10US, half off.
I am leaning towards getting the WD Wireless My Passport Pro, however in doing research on this,WD Support says it can’t read RAW files through the My Cloud App. The app shows a ? when viewing a RAW file. One option I came across would be to shoot RAW+JPEG. Then the JPEG would show next to the question mark which is the RAW file.
What I would like to do is take my photos then stick the SD card from my Canon camera into the WD WiFi drive and upload my photos. Then, go on my iPad and view them and edit the RAW photos- not the JPEG. And then once I am done editing send them back to the WiFi drive where I can access them on my computer.
Can this be done with the WD WiFi drive? Their Cloud app doesn’t seem to get great reviews, so would I need that app for this to work? Can I drag and drop the RAW photos from the drive to the photos app on my iPad and then work on them and just drop them back on the WiFi drive when done? I don’t want to use iCloud. I do have apps that can read RAW. If this won’t work, what are some other options?
The WD drive CAN read (and write) RAW files; what it can't do is make previews for them.
That workflow would be way too much work for me. The process of using external storage on an iPad Pro is rather clunky and not at all as easy as the desktop. I'd use the external for backup, and copy all the RAWS to the iPP and then mercilessly cull down to some few you wanna work on and edit. Then send those to the external for backup. Relying on the cloud when traveling can be frustrating, so account for that.
I don't think the iPP is very good for wholesale editing. On the desktop, I'd run some presets on 'em in Lr and add WB adjustments, some quick develop, camera calibration, lens correction, and a slew of metadata changes, even before a second cull (first cull just gets very obvious mistakes). But that just isn't as practical on the iPP. I use it mostly just for images I wanna do a lot of custom adjustments on. And in iOS serious metadata editing, even in Lr CC, is a PITA.
I'd suggest you consider how a very mobile workflow might differ from a desk workflow, and how you can maximize the iPP's strengths, like editing individual images. Even at home I use it now for some work I used to do in Lr/Ps on the iMac.
