You can create bold vivid rainbow lighting when light painting at night. This works especially well with plain surfaces such as cinder block. Here’s how you can create rainbow light painting in three easy steps.
Adding color interest to a plain building
Looking at the remains of the abandoned two-cell jail, I saw that it was a rather plain gray surface all the way around. Light painting is endlessly creative and gives you the opportunity to add extra color if you wish. Here, I decided to create a rainbow color rather than a single color for one of the photos.
The light painting device that I use, the ProtoMachines LED2, produces any light within the RGB spectrum. I realize that many people do not have one of these. However, there are other lights that do this, including LED panels such as the Luxli Viola.
Step one: The exterior
I light painted the exterior from the right side of the building with a warm white light. I did this not only to make it brighter, but also to pick up some of the detail.
Rather than blasting it from straight on, I illuminated the building from a 90-degree angle to the front. I cover light painting at specific angles in this article.
Step two: Inside the left cell
Walking inside the left cell of the jail, I hid behind the door so the camera lens wouldn’t pick up me or any direct light from my ProtoMachines LED2 light painting device. I held the light closely to the wall. Starting from the top, I slowly illuminated the wall while simultaneously altering the color control so that it would gradually shift by the time I got to the bottom of the wall.
Step three: Inside the right cell
I walked to the cell on the right and did the same as above.
Most of the time, I tell people that they can replicate the sort of lighting I do with a decent LED flashlight as a Streamlight or Coast flashlight and some gels from a Roscolux Swatchbook sample booklet. While it might be technically possible if you continually swap out gels and do some blending of colored lights, it would be considerably more challenging. Also, it would be even more challenging to replicate the same colors on both cells as I have done here.
