In the first three weeks of this month, the Project 52/Framed group took a disciplined approach to tone in composition. We explored the effects of enforcing consistency of tone in our backgrounds and often even our subjects:first bright/high tones, then low/dark tones, then a middle level. The resulting mosaics of our collected photos at whowebecome.com were remarkable for their cohesiveness and harmony. This week, expect some more variety as we each explore mixing tones in creative ways. Some of us will reintroduce dramatic contrasts to our compositions by combining different tones. Some may toy with the expected mood conveyed by tone, for example with a serious expression from a subject in a light, airy high-key photo. Others will play with tone in post-processing,perhaps with split toning of black and white photos, a technique that goes back to the days of the darkroom. The “split” part of the technique introduces a color cast that can be isolated to highlights without affecting the mid-tones or shadows, or vice versa. In this scene from Natural Bridges State Beach in Santa Cruz, CA, on an overcast day, the original lighting was fairly flat. Adding blue to the highlights and brown to the shadows created a sense of depth and richness.
