Red Sparks
Art merges with science to create interesting photographic effects in this multicolored Tesla coil image.
This is a single photographic exposure. It is done in two parts.
Firstly there is a normal flash photo with Tesla coil off and in darkness. This outlines the ladder and me in normal colour. After this the shutter remains open and the camera is still recording.
Secondly, I put a red filter in front of the camera. Everything after that will be tinted red. I then turn on the Tesla coil with its bright blue/white sparks now tinted red. I will be lit up from the light of the sparks in a red glow as well. So what is captured is me with natural colours plus red sparks on the same single exposure.
This can be extended to other colours and multiple colours as in multi-colored sparks.
This is the color wheel to allow rapid rotation of the colours with motorised or manual rotation. This simply gets placed in front of the camera.
Note that there is a rotating breakout point on top of the Tesla coil so that sparks will be directed to either side equally.
No photoshopping used anywhere.
