When I got my first digital camera (Kodak DC120 - 1998, a whopping One 1 Megapixel!) I started taking pictures with my daughter by holding the camera out at arms length and just pointing it back at us. I have never given her any insructions other than 'hey, let's take a picture'. Whatever pose or expression she has, they are all her own doing. Sometimes, others will join us, with unpredictable results!
These pictures are, for the most part, as they came out of the camera. When I get more time (and a little more expertise in Photoshop) I may go back and try to clean them up a little.
