This is too cool for words. Now you can create a 7 frame animation loop on a single collodion wet plate.
A description of how spectral response curves are generated for collodion films.
The traditional method of finishing a plate is to varnish it after it's thoroughly dry. This is done by carefully pouring a sandarac varnish over the warmed plate and drying it over a lamp or heater.
Pour the collodion slowly but steadily onto the center of the plate. As you pour the collodion, it will form a circular pool in the middle of the plate...
How to prepare glass for use with collodion films.
Things to know when using pre-coated aluminum sheet for tintypes.
The spectral sensitivity of collodion is markedly different than what the eye sees. Here are some comparisons.
How to use a modified sheet film holder with wet plate collodion.
How do the different colors of light interact with the iodides and bromides in collodion film?
For crisp clean images, avoid excessive development times.
Because the wet-plate lab deals with a wide variety of potentially hazardous materials, the first order of business is to learn about the materials, their hazards, and how to handle them safely.
The "usual suspect" for collodion that peels or lifts from the plate is a plate that has been inadequately cleaned.
For relatively simple problems, trouble shooting a process can often be done on the fly using a little common sense...
When we make the reasonable assumption that for daylight conditions, UV light intensity tracks uniformly with visible light intensity, we can use a light meter to help us estimate our exposure...
Understand how the quality of light changes throughout the day and seasons, and how best to manage these effects when making collodion exposures.
A step by step tutorial showing you how to mix ferrous sulfate developer for use with collodion photography.
A tutorial for making your first tintype.
A comparison of the spectral sensitivity of collodion film with several common light sources to determine their relative efficiencies.
