The Lomography Color Lobster 110 200 ASA is a high-quality, color-negative film that is reverse-rolled to expose through the base of the film, instead of directly to the emulsion, to produce dramatic yellow-, red-, and orange-toned photographs. When the film is exposed through the base, the conventional top blue layer is partially exposed, and the bottom red layer prevents the blue light from fully reaching the blue and green layers, thus creating a reddish appearance. You can control the amount of red coloring by over-exposure to push the coloring to a yellower palette. Lastly, the film has a nominal sensitivity of ISO 200/24.
