Alternate Processes


What Are Cyanotypes?
Cyanotypes are a photographic process that produces a blue-print like the one shown above. The process involves two chemicals: ferric ammonium citrate and potassium ferricyanide. This solution is used a sensitizer solution that is applied to a receptive surface such as paper or cloth and dried in the dark. Prints are made from negatives and positive images are produced by exposing them to UV light. 




What Are Daguerreotypes?
A photographic process that involves a sheet of silver-plated copper and fumes that make the surface of the surface to be light sensitive. Expose it in a camera and fuming it with mercury vapor to remove its sensitivity to the light by liquid chemical treatment. Then rinse it and dry it and seal with protective seal such as glass. 




What is Gum Bichromate?
Photographic printing process that is based on light sensitivity of dichromates. It is a multi-layered process that produces a wash of different shades of colors. Its all about layering different colors onto the original photo to increase saturation. Uses printmaking making paper to withstand extending soaking periods for multiple layers being exposed to the sun.

Photographers use contact sheets to show the evolution of their photos. The idea of the sheet helps people identify what the original photo looked like, so they can see the change that the photographer went through in editing and making a new version of the original. The edits used in the contact sheet was all made in Adobe Lightroom.

Lumen Prints Paul Sisson http://www.paulsissonphoto.com/lumen-prints/ Joshua White https://www.joshuawhitephotography.com/lumen-prints/ Lumen Prints were an early form of photographic processes that involved UV light. First you need to arrange physical subjects on your paper until you get the desired arrangement. Then, you need to cover your subject with a piece of glass, while making sure that your subjects are flat on the pieces of paper. After placing your glass on, place it outside and make sure that it is directly pointing towards the sun. It is best to complete this process when there is UV light (sunlight) as it is what creates the image. Make sure to monitor your photo and tape your photo to the ground as it absorbs the sunlight. Once the print has been developed by the sun make sure to take it out and bleach it then wash.
