For both the wife and I....our images on SD cards are copied into iPad Pro and into WD Wireless Passport Pro (we still have the HD version, not the newer SSD version). We do the initial cull on the iPad Pro for errors in focus and composition. If we need to to do an edit in the field to give someone an image, we use any editor we have on the iPads such as Lr CC. Affinity Photo, Raw Power,...etc. Then we can either airdrop the image to the person, email it to them or, use the Passport Pro to copy to a USB memory stick to give them.
Final edits are done back home on iMacs with larger screens and a wider choice of editing apps. We use image capture on the iMacs to copy in all the keepers on the iMac. On our 512K iPads we could import 15,000 raw images. With one of the new iPad Pros with 1TB of storage, we will be able to import over 30,000 raw files. We would have to be on the road for over a month to generate 30,000 raw images. 😉
