Eight Light. They provide indirect light to improve videos. When these lights are used, the on camera light provides fill light to reducethe harsh shows. Sometimes, the fill light is not needed, for example, when suspended particles are in the water. Light from the LEDs around the camera bounces off these particles and goes directly back into the camera. This is a type of glare that reduces the quality of the image in several ways. GeoVISION stainless steel cameras has an on/off switch that allow the operator to turn off the camera lights and use only the supplemental lights.
The camera On /Off switch allows the user to turn the LED's mounted around the lens of the GeoVISION Standard, nano, and micro cameras on or off depending on the situation.
|The left column shows the borehole with light provided by the Super Eight Light only.||The right column shows the borehole with light provided by both the camera lights and the Super Eight Light on.|
The first two images below have no glare, as indirect
rarely produces glare.
The Super Eight Light which is located above the camera in these images is on and the "On Camera" lights are off.
|The first two images below show glare from suspended particles and the bore hole walls. "On camera" light produces glare, because as with most borehole cameras, the LED lights are next to the camera lens. This causes the light to reflect directly back into the camera lens.|
|There are no suspended particles in this image. The indirect lighting from only the Super Eight Light give shadows that give the perception of depth||There are no suspended particles in this image. The direct lighting from the "On camera" lights removes the shadows and give a flat appearance.|
|Light from the Super Eight Light bounces off the borehole walls providing indirect light, which gives the image much more texture and depth with no glare.||Light from the on camera lights bounces off the suspended particles in the water causing glare.|
|The images below show texture and depth since the off camera Super Eight light produces shadow as the light comes from behind the camera and bounces off the borehole walls. Indirect light is an important factor in photography and in obtaining images that are easier to understand.||The images below have a flat appearance with little texture, since there is no shadow. Most of the light comes from the "On Camera" lights, which are very close to the camera lens.|
