This is the second image from the machine shop that I visited last week. It was fairly light inside the shop,so exposures could not be any longer than 8 seconds, which complicates the whole light painting process, unless of course you are using flash, which I find slightly harder to control in these situations. The reason I prefer flashlights is because I can do a quick test run at certain angles to see what looks the best before tripping the shutter. The various tools used in this shop are quite impressive, and personally I have never seen drill bits on such a heavy-duty scale. The rustic old cart full of tools was just perfect for light painting,and the lathe provided a nice backdrop for the cart.
