And how to reduce it, and get the sharpest images possible. White light is made up of a complete spectrum of different wavelengths of light. The visible wavelengths range from 400 nano-metres (violet) to 700nm (red). When a simple lens focuses light, the different wavelengths are focused at slightly different distances. In a photograph, this would…
How to optimise strobing lights, so only they’re only seen by required cameras
When two cameras are looking at the same subject from opposite directions, and require different lighting (as one camera would be looking straight at the opposing lights), if camera A and strobing light A are out of sync with camera B and light B, each would only benefit from its own light source, and not…
LED Lighting – the cool solution for high speed imaging
High speed imaging requires a short shutter speed, and therefore a lot of light. Traditional tungsten lighting produces high quantities of heat, which can cause tremendous problems. LED lighting offers significant benefits over tungsten lights, not only as they output negligible heat, but also: White LED lights are daylight coloured so can be mixed with…
