Two sets of cyanotypes (above) are incorporated
into the final print (below). In one set, a pigeon interrupts Dr. Shell's
action. In the other, there are camera problems with frames 11 and 12
of the front foreshortenings. Muybridge chose to print only the laterals
and the rear foreshortenings in the final collotype.
Roll your mouse over the highlighted frames
for a closer look.
