LightArray Control Panel

This guide provides instructions for operating and managing LightArray through its integration with Arago Control. Please note that this manual may be updated as the software continues to develop.

1. Main Panel

1. LightArray connection toggle
Used for enabling and disabling the connection to the LightArray Controller. There are three connection states:

• Disconnected
• Pending. In this state Arago Control is querying the network for any available LightArray.
• Connected. Once connected the fans are automatically turned on together with the Model Light (if applicable).

2. Continuous Light toggle
This mode is helpful for verifying and fine-tuning the cross-polarization alignment between the FlashLED and the polarizing filters. The modeling light can also assist the camera in focusing when ambient light is insufficient.

3. Polarizer toggle

The toggle changes the electronic polarization state (ON/OFF). The toggle is interactable only when operating in Flash Mode ALL.

4. Flash Mode dropdown
There are currently 5 predefined triggering modes:

• ALL
  This is a standard one-shot mode triggering all 4 Flash LEDs simultaneously, typically used for regular photogrammetry workflows. This mode uses the currently selected Polarizer state.
• ALL + PALL
  This is a two-shot mode triggering all 4 Flash LEDs simultaneously – once with Polarizer state OFF and once ON.
• OLAT
  OLAT stands for one-light-at-a-time. It triggers your camera with the LightArray 4 times – once for each Flash LED (from 1 to 4). The Polarizer default state for this mode is OFF.
  When using OLAT for a long period of time, we recommend to remove the magnetic polarizing filters from each Flash LED unit.
• OLAT + POLAT
  In addition to OLAT, this mode also triggers a POLAT (polarized-one-light-at-a-time) set of images. It triggers your camera with the LightArray 8 times – twice for each Flash LED (from 1 to 4) in both ON and OFF polarization states.
• OLAT + PALL
  An extra polarized image is triggered with all lights on in addition to an OLAT sequence.

5. Trigger Mode dropdown
The trigger mode corelates to your camera Drive Mode. We currently support Single and Continuous drive modes. Arago Control automatically detects this setting from your camera if the Camera Tethering feature is active and the camera has been detected.

6. Help Button

7. Shoot Button
This button triggers the currently selected LightArray Flash Mode.

Using this button will also help calculate travel time estimations by measuring how long it takes to complete the selected sequence. The sequence execution time depends on the camera settings such as drive mode, shutter speed, memory buffer and so on.

2. Power Levels

For example, when using OLAT+PALL the LightArray will trigger one flash at a time and all 4 flashes for the PALL image. The amount of light will be evidently higher with all 4 flashes turned ON in the PALL mode compared to one flash per image and the power levels should be adjusted.
