Auto Focus Button
The auto focus button is located at the bottom left corner of each camera controller. Press to
automatically set the focus when you have an active lens that supports electronic focus
adjustments. It’s important to know that while most lenses support electronic focus, some
lenses can be set to manual or auto focus modes, and so you need to ensure your lens is set to
auto focus mode. Sometimes this is set by sliding the focus ring on the lens forward or backward.
Click on the auto focus button or drag the manual focus
adjustment left or right to focus a compatible lens.
Manual Focus Adjustment
When you want to adjust the focus on your camera manually, you can use the focus adjustment
located at the bottom of each camera controller. Drag the wheel control left or right to manually
adjust focus while viewing the video feed from the camera to ensure your image is nice
and sharp.
Camera Gain
The camera gain setting allows you to turn on additional gain in your camera. This is important
when you are operating in low light conditions and need extra gain in the front end of your
camera to avoid your images being under exposed. You can decrease or increase gain by
clicking on the left or right arrows on the dB gain setting.
You can turn on some gain when you need it, such as outdoor shoots when the light fades at sunset
and you need to increase your image brightness. It’s worth noting that adding gain will increase noise
in your images.
Shutter Speed Control
The shutter speed control is located in the section between the color wheel and the iris/
pedestal control. Decrease or increase the shutter speed by hovering your mouse pointer over
the shutter speed indicator and then clicking on the left or right arrows.
If you see flicker in lights you can decrease your shutter speed to eliminate it. Decreasing
shutter speed is a good way to brighten your images without using camera gain because you
are increasing the exposure time of the image sensor. Increasing shutter speed will reduce
motion blur so can be used when you want action shots to be sharp and clean with minimal
motion blur.
White Balance
The white balance setting next to the shutter speed control can be adjusted by clicking on the
left or right arrows on each side of the color temperature indicator. Different light sources emit
warm or cool colors, so you can compensate by adjusting the white balance. This ensures the
whites in your image stay white.
