The Ancients knew the Camera Obscura,
a Dark Room with a small hole in the streetside wall.
The hole focuses the Light coming through it,
projecting an inverted image of the scene outside on the inside wall.
Centuries later, Chemists created Photosensitive Emulsion,
trapping time and light in crystals of silver.
The image on the film is negative,
with white shadows and blackening beams of light.
In another Dark Room you stand
in a dull amber glow,
taking a negative, making a positive,
working blind, awaiting process.
