Marshall Electronics Offers Three Levels of ND Filters for Its Cameras

Marshall Electronics now offers three levels of Neutral-Density (ND) filters for its IP67-rated CV226 All-Weather Lipstick Camera and CV503-WP All-Weather Miniature HD Camera.

In photography and optics, an ND filter reduces or modifies the intensity of all wavelengths, or colors of light equally, giving no changes in hue of color rendition. It can be a colorless (clear) or gray filter and is denoted by Wratten number 96, a labeling system for optical filters. The purpose of a standard photographic neutral-density filter is to reduce the amount of light entering the lens. Doing so allows the photographer to select combinations of aperture, exposure and sensor sensitivity that would otherwise produce overexposed video.

Free-D protocol support now comes standard on Marshall CV730 and CV630 models and is available for existing customers through a free firmware update. Marshall says Free-D protocol is an industry-standard protocol, supported by major AR/VR solutions providers. Through this firmware update, the CV730 cameras will feed tracking data over IP back to command central, using Free-D communication. This enables the cameras to directly respond with pan, tilt, zoom, focus, iris and axis position in real time, making VR/AR production simple and cost-effective without the addition of other tracking devices or systems.

Marshall also adds Color Matrix to the CV566, CV568, CV366 and CV368 cameras. Color Matrix claims to create “a more accurate color representation with master level, master phase, color level and color phase enhancements.” Controllable remotely with Visca over RS485 from Marshall RCP controller, camera control software or third-party control decks such as Cyanview, Skaarhoj and others.
