I recently discovered zoom on my iPhone camera. Funny thing about Apple stuff. I read the manual for my Mac Plus (back in 1986), but none since. I love manuals, but if I don’t get one on paper, I am not likely to look it up on line. So, if a feature isn’t on the first screen or a menu or two away, I may never find it. Seems like zoom can only be conjured with a gesture (here, a pinch). Zoom isn’t that great, though. I believe the camera lens to be fixed, so zoom is probably just cropping before you take the picture (you lose pixels).
Hope your day is filled with even pleasanter surprises.
