Thanks
I just bought it having read that the ARW format on the RX100 mk IV was the same version as for the RX100 mkIII. It seems to work just fine with the few test files I took earlier & already had played a lot with canon CR2/50D files.
Currently using Bridge + Affinity together.. very nice setup considering its just a hobby for me. I would love a DAM that doesn't try to sell me CC and install resident stuff on my mac, although this seems to be a good combination at the moment and theres a cross platform aspect to Bridge that might be useful for the family wintel laptop. Great piece of software, nice UX.
Now going to take a look at Designer. I didn't realise I needed it until I looked. I'm an easy cross-sell.
