Sun pictures are made by arranging objects directly onto a piece of photographic paper and exposing them to the sun.
Some of the earliest photographic experiments were produced using a similar method by William Henry Fox Talbot and Anna Atkins as far back as the 1830s. Lunar graphs, i.e. pictures made from the light of the moon, could also be made, although much longer exposure times would be necessary for these.
Although they share similarities, the difference between sun pictures and photograms is that to produce sun pictures you don’t need an enlarger. Also the results produced have a violet or sometimes bluish tint rather than being black and white.
Chocolate ALWAYS helps.
