 About
Video Lights:
 To qualify as
a video light, a light source must have a high colour temperature
(3200K or greater) and must provide even illumination (freedom
from hot-spots). Ordinary torches are not good enough for the
job, but video lights serve as excellent wide-beam torches. For
motion picture photography, a video light should preferably be
fixed rigidly to the camera housing by means of a lighting support
arm.
For close-range working, a video
lamp may be mounted directly above the housing. In this case,
the lamp may be attached to a standard accessory shoe (if provided).
For medium-range working, the lamp should be further away from
the camera lens, and a longer articulated (jointed) arm is to
be preferred. Arms with 1" diameter ball joints can support
lights weighing up to about 3kg in air. The Ikelite 1.25"
ball-joint system can support in excess of 3Kg in air. Other
arms, particularly segmented arms, will droop when holding heavy
lights in air, but will work acceptably underwater if not excessively
loaded. See the Lighting
Brackets section for available products.
A video light can be used as illumination
for digital stills photography. Generally, the level of illumination
will not be as great as that obtainable from a flash unit; but
the video light has the advantage that it provides artificial
lighting when the camera is used in movie mode. It has been noted
by Michael Aw that
the use of a video light can reduce backscatter. |
