Kiss in the Park is my latest upload. I consider myself very lucky to have been at the right time at the right place! This shot is completely natural and unposed. (Believe me, I would have insisted on a perfect match, had I known and posed this couple :)).
On another note, I wasn’t quite ready to abandon my “artistic vision,” and so I devised a possible workaround to the square/frame issue: I uploaded two separate files in the exact card dimensions, one with a white, and one with a black background.
The image was also nudged a few clicks to the left, in order to look centered in the preview. I’ll buy a card myself to find out whether the preview placement is rendered accurately.
