B - Fine camera adjustments
Fine Camera Adjustments
Each DanioVision system is thoroughly checked and set to its optimal configuration. However, transport and handling of the system may sometimes cause slight changes in the camera position relative to the well plate, resulting in a sub-optimal video image. This section helps you restore the original settings. To open the DanioVision casing, see page 116.
Centering The Well Plate Horizontally
If the well plate is not centered horizontally: 1. Loosen the washer located behind the camera bracket, under the camera profile. B - Fine camera adjustments 2.

Example Of A Good Video Image
Check that the well plate fills the video image as much as possible, with the letters A-H and numbers 1-8 well visible. Set the camera lens to maximum aperture. The image is overexposed when no water is present. Below an example of a good video image when water is present: Tighten the three screws on the camera lens once the image is optimized.
