When I am working on editing photos, I usually check to see how an image looks when converted to black and white. Sometimes it is a surprise. Sometimes it is a no-brainer. However, sometimes it is a struggle to decide which image has more visual impact. This is an example of one such image. I like both. How about you?
For the non-technical folks: digital cameras capture raw data in a numerical format: it’s just a string of numbers. Either in-camera or in the computer, the data is converted to a set of (not entirely arbitrary) corresponding colors … or, in the case of black and white, tonal values. If converted in the computer, the photographer can make a choice of converting to black and white. If in the camera: the manufacturer decides what tonal values (and colors) are “correct”.
