A camera, a Corvette, a scanner, and image editing software. Wash and wax the baby. Park in front of a nice background. Use 35mm film, appropriate for the conditions.
Lower numbers mean higher resolution film, which require brighter surroundings.
Take lots of pictures. Develop to 5x7 or larger size. Use a color scanner. 24 bit color is good. Send the image to me so I can add it to the list.
