Thanks for sharing these. Great examples of how it's supposed to be done. Interesting that you chose to shoot the baby with a dark background. I wouldn't have thought of that.
Which camera setup were you using for these?
All the pictures are taken with my old Canon 400D in a Sea & Sea housing. Wide Angle with the Tokina 10-17mm fisheye and macro with the Canon 60mm or the Sigma 105mm.
