I have just begun using Affinity Photo and tried to open raw files from the Sony RX1RM2 camera on an iMac. This took me to the Develop section of Affinity and the file name etc came up as expected, but the image never appeared. An indicator at the top of the screen indicated the file name followed by a percentage. The screen showed the before and after displays, each with a few faint pixellated marks. The file size of the ARW files I am trying to import is 43.2 mb. A list of compatible cameras for Affinity Photo that I found includes the RX1M2, so I am probably making a simple error somewhere. I initiated the file import by simply searching for the file and using the the open instruction. Can anyone help please?
