2. THE CAMERA OBSCURA
The camera obscura is an optical device
That projects an image of its surroundings
onto a screen inside. The image appears
upside down and the camera obscura only
Works on a sunny day.
The image can be projected onto paper,
And then traced to make an accurate
representation. Using mirrors as in the 18th
century you would be able to flip the image so it was the right way up.
Another more portable type is a box with an angled mirror projecting onto
tracing paper placed on the glass top, the image being upright as viewed
from the back . The smaller the pinhole the sharper the image gets.

this "hyposulphite of soda" ("hypo") could be used as a
photographic fixer, to "fix" pictures and make them
permanent, after experimentally applying it thus in early
1839. His ground-breaking research on the subject was
read at the Royal Society in London in March 1839 and
