Establishing a Standard Exposure Time
Making contact printing proof prints from your negatives in the darkroom can provide you with invaluable information about the performance of your camera, film, and darkroom practices.
It is important to establish a standard exposure time for making and assessing your contact prints.
- Have you ever wanted to compare one film against another, or see what advantages a new developer has over the current one you are using?
- Maybe you just want to know if you are over, or under-developing your film.
- Perhaps you want to conduct your own personal film speed index and developing regime?
So where do you start? There are so many variables including your camera optics and shutter, your choice of film, developing techniques, your choice of photographic paper, chemistry, your enlarger setup, and the darkroom technique you employ.
How do you control so many photographic variables to make an informed choice?
The short answer is to establish a standard contact printing proof procedure for your film and paper combination.
