What do filters on an enlarger do?
There are two ways to filter the light coming out of your enlarger. You can use a filter set, or you can use a color enlarger which will have graduated filters for cyan, magenta and yellow. As you increase the density of the magenta filter to get more contrast, it absorbs more light.
How does contrast filter work?

What is correction filter?
Color correction is a process used in stage lighting, photography, television, cinematography, and other disciplines, which uses color gels, or filters, to alter the overall color of the light. Without color correction gels, a scene may have a mix of various colors.

Is there a limit to how many filters you can put in an enlarger?
There’s also a limit on how many can be used at one time. You can put the proper color filters above the lens and negative carrier, which requires a “filter drawer” in the enlarger head. Better B&W enlargers have these filter drawers. Cheapies don’t.
Do you need an enlarger to print B and w photos?
B&W work uses white light, but color work requires the light to be tinted through filtration. This is usually accomplished in the enlarger head. If you want to make B&W photos, all you need is a head with a white-light source. If you want to print color photos, however, the light is filtered to obtain a desired color.
What makes a diffuser enlarger different from other enlargers?
A diffuser enlarger has a translucent plastic or opaque glass between its light source and the negatives. These diffusion elements scatter light rays to produce a more even exposure and lower contrast than condensing lenses.
What are the main parts of an enlarger?
The main parts are the head, column, negative carrier, focusing stage (or base board), and wall mount. The head houses the light source and a lens or translucent material for adjusting the light. Most enlarger heads use incandescent bulbs or fluorescent tubes.
