Reflecmedia Large Blue LiteRing RM-3241 on sale and available from our online store. OpticsPlanet, Inc is an Authorized US Distributor for Reflecmedia Chromatography.
Reflecmedia's Large Blue LiteRing RM3241 is a circular arrangement of bright blue light emitting diodes (LEDs) mounted around the camera lens. The LiteRing provides all the necessary source light required to illuminate the Chromatte fabric (optional) for keying. Manufactured in two sizes, it is compatible with most digital video and professional camera lenses.
The intensity of the light emitted from the LiteRing can be adjusted with the optional LiteRing Controller. As a rule the LiteRing should be set to medium output and adjusted as required based upon distance and keying device, to achieve optimum results. The LiteRing works in conjunction with the optional reflective Chromatte fabric. Together they efficiently use the LiteRing's narrow wavelength of light to generate a brilliant but low level and even colored background, producing excellent chroma key results. They achieve this, due to the physical characteristics of the light, its direction and position, in relation to each other in a process called 'retro-reflectivity'. The LiteRing is fixed to the camera and is positioned fractionally behind the front of the lens. Lightweight and detachable in seconds, if you want to change from a blue to a green key you simply unscrew and replace with a different colored LiteRing.
Traditional chromakey often requires that you relight the background for each camera set up. With the LiteRing attached to the camera you can move from 90° head on, to approximately 10° from horizontal only requiring a slight adjustment on the optional LiteRing Controller to effect a key.
Ideal shooting distances depend on a number of variables including levels of ambient light, choice of keying applications, camera quality and filming formats. As a rule the subject should be further than 8' (2.4m) from the camera to avoid a blue or green cast of light. Maximum distance rises up to approximately 60' (20M).
