Printing my own black and white photographs in the darkroom taught me a bit about what my M6 camera and a bit of Kodak Tri X film could record for posterity. Learning about the importance of 18% grey, middle grey or zone V taught me about the importance of correct exposure in gaining from all the black & white film could give me no matter what light conditions I work in.
I have now given my Leitz enlarger away and no longer wet the floors of any darkroom floors; I now just do the ‘darkroom’ thing with a Nikon Coolscan V ED scanner, Adobe Bridge and Photoshop CS5 in my office. But my hand held Polaris light meter still ensures that the colour or black & white print film in my camera records the moment so close to how my eyes perceived it. A hand held light meter in incidence mode ensures that the high and low lights remain as just that. When I still worked my negatives in the darkroom, the negatives exposed with my hand held meter in incidence mode were much less hassle to work with. The empirical evidence in front of my eyes told me that it was much better to work with the available light then fight with it in the ‘darkroom’ or ‘lightroom’ as the process is commonly called now.
The hand held light meter in incidence mode meters the light in an as is way, deep shadows or blacks will remain as just that and high lights or whites will remain as is. If you a photographing someone in the dim shadows they will appear as such. When I am doing a portrait I sometimes reposition the subject to get some of the available highlights to fall across their face; I then take a light metering and shoot the portrait. Work with the light, don’t fight with it, you will get better pictures in the end.
Though I have given up on the darkroom, I have not stopped using colour and black & white film; and when I use film I use my Polaris light meter too.
This method of exposure gives me images that have all the tones from the highlights through to the deep dark shadows just as God gave them to us all.
