Wee Gee was a press photographer, so getting the images to the newspapers quickly for their print run was critical. These were B&W images, because that is all the news paper presses of the day were capable of running. Night time photography had to use flash, the films of those days were quite slow, but for crime scenes, that harsh light somehow worked and created tension in the product.
While flash photography tends to be counterproductive for street photography, I have used it from time to time, especially in developing countries where street lighting is minimal to non-existent.
When it comes to travel photography, I find I prefer colour as colours are in important element in capturing the look and feel of places I visit. I may do the occasional B&W on compositional grounds, but for me, these are the exception, not the rule in travel photography.
