The last time I visited the Heuston South Quarter there were rain drops on my lens so some of the images contained multiple distortions. Today I discovered that my batteries were depleted[ I had put the wrong ones in the grip] and also my Apple iPhone 12 Pro Max had failed to charge ... when things go wrong they keep going wrong. Anyway, I decided that I had no option but to use my iPhone XR which produced HEIC files which I could not use in previous versions of Lightroom. When I returned I was impressed by the HEIC images as they were better than I had expected.
