Just a tip about the camera which may be helpful to others with low vision. I fairly often use the camera to allow me to magnify something I can't otherwise see, and sometimes also to make the enlarged image more visible by inverting the colors. Being able to access the camera from the lock screen (without unlocking the iPhone or iPad), I can easily take a picture of the print sample or other image I'm having trouble seeing, then view that photo and zoom to a comfortable size by just 'unpinching' two fingers. I have 'Invert colors' set on the 'Accessibility shortcut' setting. So if I need the colors inverted to see the text/image, I can triple tap the home button to turn on 'Invert colors' - this too is available without unlocking the device.Because my iPhone or iPad is usually close at hand, I find this is the easiest way to get past those little visual roadblocks.
