I have used in three times and I think I've already gotten my money out of it. A trip to JCPenny's for pictures in their studio - easily would cost me a minimum of $40 each trip simply because I can never choose what pictures I want. Having done three sessions, I'm only a few dollars away from paying for my investment. I do need to do some research in a better place to print my photos - the upload/transfer to Snapfish breaks down the quality of picture and so I'm not getting as crisp of a picture when I get them printed, but I know there are excellent options so I'm not worried - just on the list of research to do.
The first session, I was so eager to get to snapping that I didn't even bother steaming out the wrinkles in the backdrop. Mae was just so smiley so I got going right away with it. :) I also was only using my point and shoot. My DSLR hadn't been acquired yet.
The next session I was looking to acquire some pictures to put up of the kids. I needed updated shots of them :) and so why not take some really updated one. I started with Mae while Ace was napping and then I worked with the two of them after Ace woke up and then when Mae was done I did some of just Ace.
