Can I Develop Color Negatives in Black and White?

It is possible to develop color negatives in black and white, although it may require some fiddling and it will certainly require some special contrast filters to compensate for the differences between color and black and white negatives. It is more accurate to say that you can produce black and white prints from color negatives; color film requires its own special developing process, and you cannot develop color film in a solution designed for black and white film. There are numerous advantages to developing color negatives as black and white prints, and the prints you produce can be quite stunning if you are willing to take the time to experiment with filters and exposure levels.

Color film has several layers, each of which is sensitized to a different color. When the film is developed, the exposure is fixed, creating a negative. When the negative is exposed to color-sensitive paper and developed in color developing chemicals, it will result in a color print. If you develop color negatives using a black and white technique, the color information will be retained, but the print will be in rich shades of black, gray, and white. This monochrome print can have an almost unearthly feel if it is developed well, and it is fun to experiment with color negatives in a black and white darkroom.

To develop color negatives in black and white, you will need access to a darkroom along with an enlarger and trays of photographing chemicals. You will also need black and white enlarging paper, and a set of filters. Filters are thin slips of colored gel which can be interposed between the negative and the developing paper, changing the look of the exposure. Many stores sell packs of contrast filters, often labeled with Wratten Numbers, a standardized system used to describe these filters.

When developing color negatives into black and white prints, you can try making a straight print without a filter, but the contrast usually looks very strange. As a result, you need to explore the wide world of filters. Start with a light yellow filter, and play around from there; many people recommend starting out with a four filter. You will use a lot of photo paper in this process; what you're looking for is the perfect filter, exposure, and focus. To develop color negatives in black and white, you also need time so that you do not feel rushed while you work.

To develop color negatives in black and white, load the negative into the enlarger and focus it as you would normally. Try making a test strip without a filter first, so that you have a basis for comparison. To make a test strip, cut a strip of photo paper and place it under the enlarger. Use a piece of heavy cardboard to cover most of the test strip, and turn the enlarger on. Every two seconds, move the cardboard further back, until you have a range of exposures. Develop the test strip, take it outside, and look at the exposure. Your first test strip will probably not look very good, but after several test strips using filters, you will find the perfect filter and exposure to use to develop your color negative into a black and white print.

Once you develop a whole piece of enlarging printer, using the parameters on your test strip, you may notice areas of the photograph which need touchups such as dodging and burning. Over-exposed areas should be “dodged,�meaning that you obstruct the light source with a dodging tool while the paper is exposed to reduce the amount of exposure in the relevant area. Burning involves correcting underexposure with a targeted longer exposure, typically by using heavy cardboard or metal with a small hole in it which lets light through to the area of interest.

When you develop color negatives in black and white, the process can be trying and frustrating, but the results are often very interesting. An ideal print combines the stark, clean look of black and white prints with the visually lush contents of color prints, and you can even tone the resulting print with sepia or another color for added impact.
