Moshofsky/Plant has many long hours of experience with electronic image manipulation and retouching. Many, many hours. This is a recent example of what we've done. Below is a photograph of the marquee at Portland's Fox Theater, which was rented out for this photo. A lot of the neon is damaged or burnt out--and the client wanted to have "Fox" replaced with "EXPO". In neon. Click on the photo to see how we did.
