When developing a negative film and printing in the darkroom, a split tone would often be applied to a black and white photograph at the printing stage. In doing so a photographer could change its appearance to artistically enhance the feel and emotion in the image. I have never worked in the darkroom but speaking to those that have, there is a great deal of skill, patience, expense, not to mention trial and error involved to achieve the results envisaged by the photographer. To produce a body of printed work is even more challenging, as this must require real dedication and a consistent approach to how a series of pictures are printed.
I greatly admire those photographers who still work in a darkroom and one day I may go on a workshop to learn more about it. For now though I am happy to try and apply these darkroom techniques in a digital world where the likes of Lightroom and Photoshop make the process so much easier.
