Visual Design and Presentation in Education

"The Photos app in iOS includes a built-in crop tool that works very well for quick edits on the go with the iPhone, iPad, or iPod touch. Perhaps even better, there’s a constraint tool that lets you instantly crop images to a variety of common photo proportions, ranging from a perfect square, 4×3, 8×10, 5×7, 16×9, and others taking the guesswork out of the process. No additional downloads or apps required, it’s all featured in the default Photos app."
