According to Robert Hirsch - Seizing the Light:
"Eadweard Muybridge devised a "sky shade", a shutterlike device permitting
various exposures to be made on a single plate, to compensate fot the wet
plate over-sensitivity to blue light. This let Muybridge make a single
negative, instead of the combination printer´s two, and more accurate
portray a range of tones."
