D. Preparing the camera and shooting
D7.3 For a shallow depth of field, film-like look you should
use a large aperture (f1.4 – f5.6). To avoid softening of the
image due to diraction eects you should avoid using
very small apertures (f16, f22 etc). Most lenses provide
the best performance in the middle of their aperture
range. Use the cameras built in ND filters to maintain your
desired aperture when there are high light levels.
Note that with some 3rd party lenses the iris may operate
in steps and the lens may be heard to click. This is normal.
D8. ND Filter system
Neutral Density filters are used to reduce and control the
amount of light falling on the sensor in bright filming
conditions. They allow the use of larger apertures than
would otherwise be possible in high light level scenes.
The PXW-FS7 has a system of 1 clear filter and 3 neutral
density filters to assist with exposure control. The filters are
selected via a knob on the side of the camera. The options
are: Clear, 1/4ND (2 stops), 1/16ND (4 stops) and 1/64ND (6
stops). Use the appropriate amount of ND filtration to gain
the most appropriate iris aperture.
