^I am experienced in taking picture of kids. Some of the kids I took pictures of are now in their early twenties. All kids want to be naughty. They give you the best shot when being naughty boys or girls. The children's playground is the best shooting scene of all for kids. They will be very naughty if you say to them, "If you keep on doing funny faces and postures, I will keep taking pictures of you." I like this shot for its tune and the composition.
You have inserted a photo into a photo frame, put it on the table and think to yourself, "Great shot", haven't you? Of course, that was your select photo. Undoubtedly, the photo frame accentuates the pleasing photo too.
To me, framed photos have two special characteristics. First, with the frame accentuating the four borders, the 2-D nature of the photos is visually more obvious. Second, the photos look more like a TV screen where the characters can pop up from the corners and rims. These two characteristics are actually two essential elements in composing for a scene.
To counter the 2-D restriant for the 3-D scenes, I use lots of foreground and background references in my photos or perspectives from bottom up or top down. To make use of the "pop up" surprise afforded by the photo, I sometimes let my subjects come into, exit from or peek into the rectangular area from the corners or rims.
The photo today may illustrate my points.
Try to reinforce these ideas in your mind by looking at a scene as a framed photo. As a prejudiced SLR user of old, I still recommend using a viewfinder, which gives the photographer a stronger sense in this regard.
