Cyanotypes Post








Reflection:
           For this project, I think it was so cool. The Cyanotype project let me know that how to from negative change to positive and reflect the image on the paper finally. Let me feel that it was so complicated to take one photo before. However, we have the digital cameras so we can take pictures in a second. If I do this again, I will choose an image of the portrait because I think portraits can better reflect on the paper and look better. I also will put the paper longer time under the sun so that the contrast will be better.

History of Imaging



Two of the photo processes: Tintype and the photogenic drawing are the different types of photo processes. The tintype was first described by Adolphe-Alexandre Martin in France in 1853. The tintype is a photograph made by making a direct positive film on a sheet of metal coated with dark paint or enamel and using it as a carrier for photographic emulsions. The photogenic drawing was invented by William Henry Fox Talbot. This photo process needs to prepare by soaking it in a weak standard salt solution, drying it, scrubbing it with silver nitrate solution, and then further cleaning it in a strong standard salt solution. Exposure is usually through contact printing, as long as there is an image.


Most interesting one: The photo process that the most interested me is photogenic drawing. After I search and know about this photo process, I think that is an amazing process. When I see some pictures that use in the photogenic drawing, I think those pictures are the great achievements. Although this photo process would need a lot of materials and have many steps, I think the more photographic materials and steps, the more better pictures. And I esteem all the photographers to photograph each picture so perfectly that it can be presented to people.
