DCS Operation (Camera Settings Example)

Deploying the Drop system from a vessel (exact steps determined in integration meetings)

Deployment Operation

1. Depending on the seafloor topography, the Rayfin’s angle, the speed of the current, and the lighting conditions, you have to adjust the settings accordingly. Below are some example scenarios of system adjustments:

   1. Images are blurry: Increase the shutter speed initially. Sometimes, you might also have to adjust the ISO accordingly to achieve a decent image quality.

   2. Images are out of focus: 

      1. Refer to Focus Settings Suggestion for suggestions on how to pick the reference point on the image, depending on the setup on the Rayfin.

      2. Slowly adjust the focus, take a digital still, and repeat until objects inside the reference plane seem to be sharpest.

   3. Images are washed out (overexposed):

      1. Refer to Exposure & Lighting for information on adjusting the strobe compensation and light intensity of the system.

SubC suggests starting with a camera setting of 1/60 shutter speed and ISO200. For fast-moving objects, it’s suggested to increase the shutter speed and increase the ISO value until the target in the picture appears sharpest. Please refer to the Camera Shutter Cheat Sheet for more information.
