I'm just glad so many other people are getting into light paintings like I've been exploring for the past 2 years. Yours is the first I've seen in black and white other than my own.
Photography is, in its simplest form, painting with light. I love the different lights that can be caught and the patterns they can create. This is especially true for long-exposures. Rather than focus on the effect, I want to focus on the lines and the raw idea, so black and white it is. I was tempted by the colour version here though, it looks nice.
