CV600 icon New Design
target the needs of professional photographers
provide Advanced Features at work!
Filter Library, Flicker Free setup and get a right Exposure value
these New functions are helping you to face the challenges of setting up lights

Lighting is subjective, what we see is not always what we get.
Control the light intensity (LUX) and color of light (Color Temperature) effectively
and create a connection with your audience’s emotion

The common used『White Balance Map』
for cinematographer and videographer
Now combined with modern technology
Just target your Corrected Color Temperature
Check your current lights and accurately pinpoint the right gel to use
CV600 helps you to control the light and increase the quality of work!

Filter Light Palette
Includes CC/LB
rosco, LEE Filter, Kodak, FUJIFILM
4 brands of filter library
to find the suitable color
Knowing exactly what gel to use
Save times to guess, trial and error.

A cinematic light meter with an exposure meter
Save all of your camera settings along with Light
and Color information for your personal library.
Exposure Value Compensating
Make sure every shoot are always correctly exposed

Object is moving fast
Light is emitted constantly
Camera is filming in every seconds
And Flicker happens!
Post production or reshooting are time consuming task
and not always easily repairable
