Eric Curry is an american photographer who also is well-known for light painting. Mr. Curry takes an approach very similar to Harold Ross, in that he takes multiple exposures, then assembles them later in Photoshop. Eric has a book available on light painting and this video demonstrates how he created the Airstream trailer light painting that is featured in his book.
a How-To e Book is available at
I recommend checking out Eric’s book titled Painting with Light: Lighting & Photoshop Techniques for Photographers which can be found on Amazon.com.
