About Reflecmedia Large Green LiteRing for Large HD and Film Cameras - SKU#1420673
Reflecmedia's Chromatte fabric is designed to work in conjunction with a LiteRing. The LiteRing features Light Emitting Diodes (LEDs) arranged in a circular casing that is positioned in front of the camera lens. This provides all the light required to illuminate the Chromatte background for chroma key production.
The LiteRing connects to the camera with a specially designed adapter ring, similar to those used for matte box mounting, which is attached to the inner thread of the lens. The LiteRing is then placed on to the adapter and simply locked with a single screw. This enables users to quickly release the LiteRing in between shots, or change from a green to a blue ring based upon their chosen keying color.
Reflecmedia has taken the blue or green color away from the fabric and completely removed the need to separately light the background. The ability to change the background keying color in seconds cannot be achieved any quicker - no need to hang a different drape or repaint the studio walls! Tungsten, HMI and Fluorescent lights can be large in size, expensive to power and uncomfortable to work under. Typically you require thousands of watts to light absorbent chroma key fabrics, whereas the LiteRing output of around 10 watts provides all the light required by Chromatte.
By relocating the color and the light into one camera-mounted device, Reflecmedia has significantly reduced the set-up time and overcome many of the difficulties associated with conventional chroma key.
The LiteRing is available in both green and blue, and in three sizes to fit different size cameras. Each size of ring has a series of adapters to ensure maximum compatibility with camera lens sizes. Further custom adapters and fixing mechanisms are available.
Reflecmedia Large Green LiteRing for Large HD and Film Cameras - SKU#1420673 Features
- The LiteRing works in conjunction with Reflectmedia's reflective Chromatte fabric.
- Together they efficiently use the LiteRing's narrow wavelength of light to generate a brilliant but low level and even coloured 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'.
- Configuration: The LiteRing is a mains powered and adjustable light source, made up of blue or green LEDs, arranged around and close to the centre of the camera lens (known as the centre axis').
- Location: 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 coloured LiteRing.
- Angularity: The LEDs are specifically angled to beam the coloured light at the facing concave shaped glass beads on the reflective Chromatte background. The light is then reflected back along the same axis (angle) towards and into the camera lens.
- Manoeuverability: Traditional chroma key often requires that you relight the background for each camera set up.
- With the LiteRing attached to the camera you can move from 90 degrees head on, to approximately 10 degrees from horizontal only requiring a slight adjustment on the LiteRing Controller to effect a key.
- Distances: 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 2-3m (8') from the camera to avoid a blue or green cast of light. Maximum distance rises up to approximately 20m (60').
