The laser mode requires an external laser pointer (should be purchased separately). This mode is based on the existence of a laser beam fed to the optical receiver of the device. It will trigger your camera or flash unit whenever the beam is broken.
The Laser Mode has four parameters:
Threshold: This value determines the level of the light that will be considered as a laser. The measured light level will be displayed in real time with orange bars. This will help you to understand where to set the threshold approximately to filter out the environment light. You can move the threshold bar by holding and moving circle with arrows or use "+" and "-" buttons.
When Laser beam is aligned with sensor, you will see orange colored Laser Matched text on this screen.
Delay: This parameter defines the duration between the detection of the laser break and the triggering of the camera. You can define the delay anywhere from 0 up to 999 milliseconds.
Frame: This parameter defines how many pictures to be taken in case the laser beam is broken. Once the laser beam is broken, it will trigger the camera for so many times defined with the Frame parameter. You can set the frame the number all the way up to 99999.
Trigger: This mode has 2 different options as "Flash" and "Camera".
When you choose Camera, your camera will be triggered through its USB communication port when laser beam is broken. If you choose this mode, your camera must be connected to your Flex over Camera Control Port.
Important Notice: Since your camera has a shutter lag, it is not possible to capture high speed events by triggering your camera. If you want to capture high speed events such as bullets you should trigger your Flash in a dark room to freeze the moment.
If you want to capture high speed events with Sound Mode then you should choose Flash as Trigger parameter. Please connect your Flash to your Flex through its Flash output using PC Sync Flash cable which comes with the unit. If your flash doesn't have PC Sync port then you can use an adapter. Also connect your camera to USB communication port of your Flex.
When you select Flash as trigger parameter and start the mode, you will see a status screen as below. You will see a Shutter Open/Close icon here. While Laser Mode is running, Flex will listen for laser beam broken events but trigger your Flash when it detects a sound change. You can also open the shutter by touching Shutter Open/Close icon. So, usage should be like below:
1. Set Trigger parameter as Flash
2. Open Camera Control screen and set your Shutter Speed to value such as 2-3 seconds
2. Start the mode
3. When you are ready, darken the room/studio
4. Touch Shutter Open/Close icon (Your camera will start capturing)
5. Broke the laser beam
6. Your flash will be triggered
7. Your camera will stop capturing when shutter speed duration is completed
The laser mode requires a consistent laser beam to be fed to the optical receiver of the device. The receiver is located on the front face of the device. The receiver is behind a transparent window and there is an optical lens on the window. The lens will help to focus the laser beam to the receiver.
The laser beam must hit the lens on the window. A slight movement of the laser source can move the beam away from the receiver, so make sure that both the laser source and the device are firmly mounted on a steady stand. After you have firmly mounted the laser source and the device, if the laser beam is correctly aligned to the receiver, the message on the screen will turn from "Laser Not Matched" to "Laser Matched". Seeing a constant "Laser Matched" message on the screen is the first condition of the laser mode.
WARNING: Please take every possible safety caution while you are working with a laser. Never point the laser to your eyes, other people and animals.
