Agree with everything you said.
Having said that, tomorrow morning I am going to take pictures of my 6-month old infant on a fluffy white blanket I just bought today. It will be a "tasteful" nude, shot face-on, with her little booty being visible (BUT BLURRED) in the background. She is only like 24 inches long. That is where the thind depth of field will make my cheap "nifty fifty" prove its worth!
