Anyone that would like to take a standard image and resize it to fit in the crop area would benefit. With the current set up, I am unable to decrease the size of a 1024x768 image so that more of it (e.g. a complete head) can fit in the crop area. Zooming works great if you begin with a tiny photo, but the opposite does not. It would also be helpful to have the default image sizes for anywhere in the application images are used so we can manipulate in photo editing software.
Thanks for submitting your idea! Currently, the locked 5:1 ratio is being respected so it will fit in your persona heading, which is why you cannot zoom in further.
