An enlarger is a device used in photography to project and enlarge images from a negative onto photographic paper. It consists of a light source, a lens, and a negative holder, allowing photographers to create larger prints from smaller negatives. The enlarger can adjust the size and focus of the image, making it a crucial tool in traditional darkroom processes. Enlargers are commonly used in black-and-white photography, but they can also be adapted for color prints. They play a significant role in the work of photographers and artists who prefer hands-on techniques, providing a way to produce high-quality prints from film negatives.
