Oscar Rejlander’s (1813 -1875) studio was unusual; shaped like a cone, the camera would be in the narrow part, the sitters at the opposite end. The camera was in shadow so that the sitters were less aware of it. He estimated his exposure by bringing his cat into the studio; if the cat’s eyes were like slits, he would use a fairly short exposure. If they were a little more open than usual, he would give extra exposure. If the pupils were totally dilated he would admit defeat, put the lens cap on the lens and go out for a walk!” ~ Robert Leggat, 1999
Cats, much to their delight, no longer must endure conscription for use as light meters. Instead of cat’s eyes, we use other tools to expand the usable range of light. HDR photography is one of these important new tools, as it lets us preserve exquisite fine detail in a scene. We explore the appeal of black and white HDR here, with regard to personal and visual awareness.
While the first two parts of this article looked at color HDR, this article investigates key qualities behind interesting black and white HDR work, with suggestions for a B/W workflow. First, we consider why HDR imaging techniques leave the feline method in the dark.
Why black and white HDR?
Think of each black, grey and white picture tone as a separate instrument in an orchestra. Filling out the tones is like adding extra players to the ensemble. Just as your musical experience in listening to the Boston Pops is different than hearing a quartet, so does a wider range of black and white tones in a photograph allow for a greater reach of emotional expression.
B/W HDR also solves an old problem. When photographing everyday scenes, brilliant whites and deep blacks can result in washed-out highlights on the one hand, and blocked-up shadows on the other.
HDR bracketing and multiple exposure, help manage this lack of tone control. In Photos 1a and 1b here, compare the HDR multiple exposure at left with one single exposure at right. Shadow details are excellent in the HDR image and the daylight outdoors is not washed out because of the greater highlight detail captured during the HDR process. By the way, there was a cat in the bar but it was too dark inside to see its pupils.

1a. “The Bull, Key West” A six exposure HDR image with 1-stop bracketing, and Tone Mapping in Photomatix Pro 2.4. Highlights show much better detail
1b. A Single Exposure taken in the middle of the bracketed series. There is loss of both highlight and shadow detail.
What Makes Black and White HDR interesting?
Tonal Range, Visual Elements, Photographer’s Personal Qualities
The alchemy of B/W HDR is to make the unseen visible. One of the implied, unseen elements in photography is the movement of time. In the B/W HDR composition above, revered names of people who were killed in the Holocaust seem to recede without a fixed vanishing point, and so to go on indefinitely, conveying a sense of the infinite.
