We need a 1x, and 3x zoom feature so that customers aren't squinting their eyes to place their logo correctly. And allow the site owner to prepare how zoomed in the "3x" is. Like a box they can adjust.
For example: For customization of a guy wearing a crewneck, the zoomed out is "1x", while a "3x" zoom can be his torso-up instead of having his legs and head in the shot, where they can be cropped out. This zoomed in feature can allow the customer to better place their logo where they want.
