Tiffen Lowel i Light - Manual (Page 4)

id-light notes:
When using the id-light, keep in mind that its lamp will shift
its color temperature warmer as the light is dimmed.
If you find a particular dimmer setting that you use most often,
store a white balance in your camera with the light at that
dimmer setting. Then use a grease pencil to place a mark
on the body of the light that lines up with the white line on
the dimming control. In the future, you can return to that
dimmer setting quickly and have a prestored white balance
for it in the camera.
Use the focusing knob
to move from Spot (narrow beam) to
Flood (wide beam). Its 5:1 focus
ratio (when used with a i-100 lamp)
means that the spot setting will be
approximately 5 times as bright as
the flood setting (at full brightness
for id).
The i & id have a high intensity reflector & prismatic
glass installed. This combination gives an even output with
a fresnel like quality in the shadows, an evenly dispersed flood,
and a uniform spot with significant barndoor cut. It is capable of
throwing sharper shadows when used on its own. Add a diffu-
sion glass swing-in accessory, diffusion gel with a gel-frame, or
attach an umbrella to create a softer source.
Use the rotating barndoors to trim unwanted output spill,
(for example: to reduce risk of shadow in your shot caused by
use of overhead boom microphones). Flexi-shafts & Tota-flags
can also be attached for increased light control options.
i & id-light for the New Professional
Because the i & id-lights are tungsten-halogen
sources, their color temperature will be aprox 3200°K (at full
brightness for id), To use the light in locations where its output
will mix with daylight (5600–6500°K ), its color temperature
can be converted by attaching a Dichroic Filter swing-in acces-
sory, or adding day blue gels to the Pro & i gel-frame. Both
will give more realistic daylight white-balancing in video or
film. Using gels will give more versatility since they are avail-
able in 1/2 & 1/4 strengths of full blue. Note: adding day blue
gels or dichroic filters will reduce output.
Swap the Prismatic Glass to Clear Safety Glass for
non-focusing higher output Super-Spot. This can be useful
when lighting a small area from a greater distance, where higher
output is needed. For faster switching on location, try using
Clear Safety Glass in the front housing & placing the Prismatic
Glass in a swing in accessory holder. Use the light for normal
focusing with the accessory swung in, and then swing it out of
the way for quick switch to super spot.
For more reduced spill, consider adding a Snoot.
Other front accessories can help vary the quality of
the light output. For example, the rotating half-scrim can
allow you to reduce light output on a close subject while still
illuminating subjects further away with full output. The full
scrim reduces output without the use of a dimmer which can
shift the color temperature warmer as the lamp is dimmed.
The oversimplified diagram below shows some of the
ramifications of positioning lights for different subject types
& lighting effects. This diagram is only useful as a start-
ing point for new pros. All subjects & scenes are dif-
ferent and make different demands upon lighting. The
height of the lights & camera, and the subjects angles & reflec-
tivity must be considered.
Use the i & id-light as a convienent, lightweight, DC powered source
for a flexible key, fill or back-light that goes places that the AC cable can’t.
Adding accessories will extend your creative possibilities.
