In order to maintain the darkness of the room, they are generally reached via several curtains or doors which are often able to help with avoiding any light pollution. This is a vital step to take to make sure the darkroom isn’t exposed to light in those times that a photographer is working on a task that could be very sensitive to light exposure. Film and prints are highly sensitive to light so it is important that the artist is able to remain in a highly dark environment to avoid any clouding or fogging appearing on the finished image.
A regular darkroom that is outfitted to complete the most basic tasks is likely to feature a wide selection of chemicals for developing the photographs, and an enlarger machine for helping to make the print. In the process of developing the film, the photographer is likely to expose sheets of photosensitive paper to a source of light using the enlarger, which is then followed by placing the photographs in an assortment of chemicals to help with developing and bringing out the image. Solutions are used to stop the development process and to rinse the finished photograph of chemicals. On completion of the development process and the paper is dry, it is then acceptable to expose to normal light.
Since it can be quite expensive to set up a darkroom, a photographer that is just starting out is likely to use a rented room for the process of developing the images. A rented darkroom comes fully equipped with all the necessary equipment for developing the photographs in a safe and efficient manner. A professional photographer is likely to refer working in a more private darkroom in the process of developing the film photography since this is often able to offer a more peaceful environment and therefore better for being able to focus on the job at hand.
