Wow, thank you so much jtk for the feedback. Much appreciated. In the original post, that particular built-in conversion to black and white on the iPhone really drives the highlights up. I did not realize it was going too far. I tried it a different way. I think I may have tamed it a bit, but I am not sure how to post a mulligan within a thread.
@jon koss Yes..like Apple, Android phones also kill future potential of files with the internal shortcut processing. Better to send to PC and save as TIFF.
