The TIV-140B is similar to the TIV-200/300 models, without the
advanced features such as burst mode and delay-before-filming.
But it does have intervals from 1 second to 15 seconds which
are set with digital precision using the two thumbwheels on
the unit. You can shoot fast 1/30th
second exposures using the "I" setting on your Bolex, and it also
has two crystal-controlled shutter speeds of one-half and one second using
the "T" setting on your Bolex. These longer speeds can be used
for filming animation, computer screens, low-light scenes, or with the appropriate
ND filters, for giving an organic blur to daytime time-lapse subjects.
Introduction
Note the following improvements:
The nylon pushrod coupling is screwed into the control box (there are two, one
is a spare). Power is supplied by 4 AA batteries. The switch at the front of
the control box is used to turn the TIV onDo not connect a 9V battery to the
battery snap—your TIV will be instantly transformed into a fancy paperweight.
The batteries will last a very long time. When they need replacing, the TIV will
let you know by running sluggishly.
Setting Frames to Expose
The TIV-140B can be programmed to automatically stop filming once the desired
seconds of film have been exposed.
Turn the thumbwheels to the number of seconds of film you want to exposure, from
1-49, and press and hold the pushbutton until both lights flash. Release, and
now frames is programmed. When you start filming, the TIV will expose the number
of seconds of film programmed and then return to idle mode.
Setting the Interval and Filming
Turn the thumbwheels to the desired interval in seconds, any number from 1-15.
Press and release the pushbutton, and the TIV will start exposing frames. To
stop filming, press the pushbutton.
Setting the Shutter Speed (duration)
You can set the I-T lever (or knob) on the side of your Bolex to I, for standard
1/30th second exposures.
The TIV-140B also can hold the shutter open for a half-second or 1 second.
To set 1 second exposures, turn the thumbwheels to "51" and press and
release the pushbutton. To set 1/2 second exposures, turn the thumbwheels to "52" and
press and release the pushbutton.
To return back to instantaneous exposures, turn the thumbwheels to "50" and
press and release the pushbutton.
When time-exposures are set, the green light will flash at idle, instead of the
red light.
Note that for time-exposures, interval now refers to the time between exposures.
Shooting Single-Frames
Of course, you don't need an intervalometer to fire off one frame at a time.
However, the crystal-controlled long-duration (1/2 and 1 second) speeds of
the TIV-140 can be used to film animation or even computer monitors (flicker
free!).
Set the shutter speed, then turn the thumbwheels to 00. Every time you press
the pushbutton, a frame will be exposed.
