Albumen
The albumen process is pretty sweet. More a coating than a specific process, albumen prints use a coating of Albumen (egg whites) and salt to create a nice surface on top of the desired paper, and allowing the one making the paper to place the light-sensitive silver nitrate on top - this produced a much sharper image than the other processes of the time, and also just looked sweet.

After you decide this is what you wanna do, the next step is to de-yolk about a dozen eggs, and whisk them in a container (shaking works well too) and do so VIOLENTLY until you get a nice foamy goo.

First, you have to make your solution:
500ml of egg white (12 eggs): These need to be agitated VIOLENTLY in order to get the mixture to be efficient. Letting the foam settle and the whites age (rot) for a while will give better results.
15-g ammonium chloride or salt
15-ml distilled water
2-ml 28% acetic (glacial) acid
15-g sodium citrate (optional preservative)
2 drops Kodak PhotoFlo (optional)
Paper can be divided with tape, although a slice-and-part technique before taping will
The coated paper is placed under a photo negative, and then glass to keep it in place. The contraption is then exposed in sunlight.
The paper is then rinsed in a solution of water, and then
