Cable

Got a SD to lighting dongle to get the photos from camera onto the phone quicker. WiFi is nice, but so slow and painful to set up every time.

This works really well. But there's something wrong with processing RAW files. I'm using Darkroom app, and the quality of exported RAW files is really poor. There's huge amount of noise.

I'll try using Lightroom mobile next time. Anyway, I'm now doing postprocessing on my iPhone. I rarely launch Lightroom now.
