We are real fans of Mike Kelley's Photography. If you haven't seen his work, you must visit his site, http://www.mpkelley.com/ . He also has many useful tutorials on photography. He photographs a lot of high end hotels, commercial spaces and interiors. He uses light painting for a lot of his photographs. Basically, highlighting various objects in the frame with light and taking multiples exposures of the same frame. The results are stunning.
Here are a few of our own examples where we used light painting. Let us know what you think.
