If the essence of a child is movement, then a pinhole is the ideal method to
desribe it. My experience is that you can captue quiet movement easily
enough in bright sun. Anything moving throughout an exposure of more than
ten seconds will simply disappear. I enjoy playing with overnight exposures,

Having done both, my vote is clearly for contact 8x10. It depends, of
course, on the sharpness of the original image. A sharp 4x5 can enlarge

Here's my first tries. With a pinhole of known diameter at optimal distance
from the paper, ASA 3 will yield a good print at 20 minute exposure. At 7
minute exposure it looks like ASA (ISO)4 might be closer to the mark. Keep
in mind that using different ASA at different exposure time accomplishes
