Flower What they're asking for involves zero cropping. It's just changing the mosaic exposure pattern to cover a square (or user defined) aspect area more efficiently. Today if I have a roundish target that is 2x the width of the sensor, I have to make a 2x frame, and will get 2x height as well, and then throw away half of it in post. One way to understand this is to enable the panoramic mode on your phone and then hold the phone vertically while panning horizontally. Can make a square frame that way, with zero cropping.
