To created this picture you will need:
- tripod
- either 3 different colour light sources or a torch and flash gels (that's what I used)
- dark location
- and of course a subject. I used white violin
With camera securely on the tripod I have lit the subject with a torch, placing different colour gels in front of it. Make sure to switch the torch off when you're changing gels otherwise some of the white light from torch will filter through.
I have used long shutter speed, otherwise I wouldn't have enough time to lit the subject the way I intended to. As a result the background was overexposed (to my liking anyway, because I wanted it to be black). To fix that I darkened it with burn tool in photoshop.
Below images were created by applying different filters in photoshop.
