6.2.3.5.1.3. Cinefade mode
The Cinefade mode allows to vary depth of eld in lm to gradually transition between a
sharp and a blurry background at constant exposure. To achieve this eect, the cmotion
Cinefade VariND lter has to be paired with an LBUS compatible iris motor. Through the
cPRO / cPRO PLUS or cPRO ONE hand unit, depth of eld can be changed dynamically
(up to 5 T-stops within optical safe range) while maintaining a constant exposure.
6.2.3.5.2. Optical safe range
The optical safe range menu allows you to turn the optical safe range ON or OFF. With
optical safe range turned ON, the system displays recommended limits for the VariND
lter in Cinefade mode and limits the lter to ND1.9 in VariND mode. When optical safe
range is turned OFF, the Cinefade mode and the VariND mode allow a wider range for
the Cinefade eect and a VariND upto ND2.7. But, optical imperfections, such as a slight
colour cast and cross pattern may become visible in the image.
