I use an Asus mini PC. It’s about half as big as a box of cereal. It’s just powerful enough to handle the large pictures from my camera (60mp) with a 4K monitor. I use Photoshop to process my photos. Currently I’m processing my photos on an iPad Pro through Lightroom. It does pretty good but I don’t like the storage set up. Gotta figure a quick and easy way to get the photos I want to save onto my pc.
Never tried to retouch images on my ipad. How efficient is that? I guess storage can be an issue. Also, how you transferring your photos into ipad, via catalogues?
