iOS 9 non-iPhone photos cropped to fill in Photos
Since I updated to iOS 9, the Photos app now displays all the photos I've transferred to my phone from my professional cameras as "scaled to fill" (i.e. cropped-to-fill) instead of "scale to fit."
This is hugely annoying. I spend a lot of time editing my several hundred thousand image library, including hand cropping images to my personal artistic taste. I have almost 14,000 images copied onto my phone through iTunes. In iOS 8 and earlier, images were shown shrunk to fit the display, with letter-boxing (black bars) to fill the remainder of the screen. Now, the images are enlarged to fill all the space, often cropping out visually important information.
For instance, an image cropped to a square aspect ratio now becomes a rectangle. As a photographer and artist, it is unacceptable that some Apple programmer decided it would be better to override my own crop. What's worse, if I pinch-to-zoom out, I go back into the library list mode.
The only workaround I've found is to double-tap to zoom in, then double-tap to zoom back out.
If you're going to subjectively make a drastic change to the functionality, you should create a preference option to allow us to revert back.
While we're on the subject of Photos, it's too difficult to find particular images without the ability to search through IPTC metadata. It would be extremely helpful for you to add this option to Photos.
