Hello Alan and all,
Sorry the suggestion didn't work out for you on the photos. Not being able to sleep early this morning, I ran an experiment with my iPhone 7. Not being out in the barn, but wishing to keep the photo subjects Massey, I made a trip up to the toy room with my phone.
First photos are the phone in horizontal position, and the photo taken with the phone held horizontally with button to the right. Second set of photos show the phone in vertical position, and the photo taken with the phone held vertically with button at the bottom. Then downloaded them here without any manipulation on my computer.
So, at least this works as I expected on the iPhone. But I can't speak for the Android...
Cheers,
JB
