Requirements for light condition
Recommended lights to use with Futudent cameras
In order to reach optimal results with Futudent cameras, as with any camera, the light conditions have a big impact on the quality. If you are using overhead lights of the unit or loupe-mounted light, please verify the *CRI (Color Rendering Index) of the existing lights.
In general, it is recommended to use led lights with CRI of over 85.
It is not recommended to use led lights with CRI less than 85 or halogen lights. Halogen lights end up turning the image yellowish, which is why it is important to make sure you have LED-lights installed.
You can adjust the light settings also from the recording software. Just go to settings – camera settings and adjust the white balance.
Sometimes the coloring of the images is not good because of the screen used to display the footage. You can easily test if this is the case by opening the images or video you took with the camera on your phone, for example. If your footage still seems incorrect, contact your distributor to get help.
*Color Rendering Index (CRI) is the system that the lighting industry uses to measure how a light source shows the color spectrum (quality of the light). CRI is rated on a scale from 0 to 100. The higher the number the “Truer” colors look of an object being illuminated. Incandescent light bulbs (including halogen) and daylight (the sun) are rated as a 100. The below image is a rendering of how CRI can affect the color of the object a light bulb is illuminating.
The CRI number of daylight at noon is 100, because this is the natural way people see colors. Good fluorescent tubes or LED lamps have a CRI 80 or more. Anything white with a CRI 80 or more is good enough for homes. The orange sodium vapor lamp has CRI lower than 0, so they are only used as streetlamps.
You always can get more information by searching “CRI” on google.
