I would like to be able to have the option for a "full view" within the Instagram 4x5 crop. So, if I choose something that is say, 2x3, I would like an image cropped (like it is now) and then another one where it's "fit" into the 4x5 and a white or black fill for the rest of the frame so that my customers can see an entire landscape orientation. Here's a sample instagram post with what I mean and some screenshots.
