So I am gonna jump off the deep end and start to sell my prints am I selling myself short by offering 5 x 7 's for $10 and 8 X 10 for $15 ? my photos can be seen here. www.flickr.com/photos/gmack24 I am gonna print off my "top 10" as 5 x 7's to kind of feel the water. gonna sell them to my co-workers cuz most will only want that size to keep on their desk or whatever. what do you guys think ?
