Week 47 of the 52frame challenge has to do with circles. One of the tutorials within the site referred to creating a little planet photo. Not having done that before, I tried my hand.
Took a 360 panorama of the pond at our local university and in photoshop with a couple of quick clicks turned it into a circle. Most photos I've seen done this way, had buildings. I chose trees instead.
Prior to doing the above I did take some other shots using round objects.
