Introduction
The Datavideo LD1 is a Dual Colour Light Ring and LED controller for Chroma Key Studios. It is intended for
use with a Retro Reflective Backcloth such as Datavideo RF3025.
It can be used in conjunction with the Datavideo DVK100 Mk II and offers automated switching.
N.B. If you own a DVK100 and you are unsure whether it is Mk I or Mk II please check the serial no. Mk II
will be 00097180 or higher. If your DVK100 is Mk I please contact your local Datavideo Office for details of
how to get it upgraded.
Using a light ring differs slightly to conventional chroma keying. A typical set up with a Retro Reflective Cloth
and Light Ring would be something like this:
Unlike conventional Chroma Key Studios it is not necessary to light the backcloth, in fact it is better not to.
It is best to have the camera between 3 and 7 metres from your subject, and your subject at least 1 metre
from the backcloth. Providing some backlight on your subject will generally improve the keying effect, but you
can play around with your light set up to get the required feel to the shot.
We would recommend that you do not work outside, the lighting is too variable and a consistent result will be
hard to achieve.
