Iris Indicator
The iris indicator is located to the left of the iris/pedestal control and displays a visual reference
so you can easily see how open or closed the lens aperture is. The iris indicator is affected by
the coarse setting.
Auto Focus Button
The auto focus button is located at the bottom right 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.
Filter
The filter control lets you change the filter in Blackmagic cameras that have built in ND filters.
Press the left or right ND filter buttons to cycle through the options.
Camera Gain
The camera gain setting allows you to turn on additional gain in the camera. On Blackmagic
Studio Cameras, this setting relates to ISO. This is important when you are operating in low light
conditions and need extra gain, or ISO, in the front end of the 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. On Blackmagic Studio
Cameras, this setting relates to shutter speed.
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.
