# intval2 Quickstart
|
||
|
|
|
||
|
|
## Attaching
|
||
|
|
|
||
|
|
1. Disengage the Bolex motor by switching the lever at position **M** to **O**.
|
||
|
|
2. Set the camera trigger to **M** (opposite **P**).
|
||
|
|
3. Place the intval2 on the camera, lining up the 4 standoff posts with the 4 exposed metal mounting points.
|
||
|
|
4. Line up the intval2 key to the Bolex 1:1 shaft so that it fits snugly.
|
||
|
|
5. Place the 3.5mm screws into 3 of the standoffs, one above the 1:1 shaft, one below and the other in the back top area of the intval2. The standoff underneath the buttons is not accessible.
|
||
|
|
6. Tighten the 3.5mm screws to secure the intval2 to the Bolex.
|
||
|
|
|
||
|
|
## Powering
|
||
|
|
|
||
|
|
Power the device using a 12V DC power source with a 2.1mm center-positive barrel connector.
|
||
|
|
Ensure that the power supply can output at least 1 Amp to ensure there is enough force to drive the motor.
|
||
|
|
You can use a portable battery designed for recharging phones as long as it is capable of outputting 12V.
|
||
|
|
|
||
|
|
Plugging and unplugging the shutter release cable will trigger a frame so ensure that it is plugged in before powering on and removed before powering off if you do not want to unexpectedly advance or rewind the camera.
|
||
|
|
|
||
|
|
## Using
|
||
|
|
|
||
|
|
Using the intval2 is simple and relies on the settings made available by the 3 buttons on the side and the shutter release cable.
|
||
|
|
|
||
|
|
### Shutter Release
|
||
|
|
|
||
|
|
The shutter release cable uses a 3.5mm audio cable and a simple switch to trigger a frame.
|
||
|
|
Pressing the shutter release cable button for longer than 1 second and releasing starts timelapse mode where the camera will shoot frames continuously.
|
||
|
|
The other buttons change settings that will take effect when you trigger each frame.
|
||
|
|
|
||
|
|
Keep in mind that plugging and unplugging the cable while the intval2 is powered on and attached to a Bolex will trigger a frame.
|
||
|
|
|
||
|
|
### Direction
|
||
|
|
|
||
|
|
The direction button, labeled "DIR" and usually red, will change the direction of the camera from forward to reverse by pressing it for longer than 1 second.
|
||
|
|
Press it for less than 1 second to reset it to forward.
|
||
|
|
|
||
|
|
### Exposure
|
||
|
|
|
||
|
|
In normal mode the camera completes a frame in ~500ms, which after accounting for the shutter angle and the prism light loss, is roughly equivalent to 1/5 second exposure.
|
||
|
|
|
||
|
|
Change the exposure of the camera by pressing the button "EXP", usually green, for longer than 1 second.
|
||
|
|
However long you press the button is how long an exposure the camera will make.
|
||
|
|
Once set an exposure will be taken by opening the shutter, waiting for the appropriate amount of time, and then closing the shutter.
|
||
|
|
Press the button for less than 1 second to restore normal exposure.
|
||
|
|
|
||
|
|
### Delay
|
||
|
|
|
||
|
|
The "delay" feature determines how long between frames the intval2 will wait when running in timelapse mode.
|
||
|
|
|
||
|
|
Change the delay between frames by pressing the "DEL" button, usually blue, for longer than 1 second.
|
||
|
|
Similar to the others, press it for less than 1 second to reset the delay to 0.
