If you are shooting outside, or using flicker free lights, you can also manually select a shutter
angle by double tapping the current shutter indicator at the bottom left of your screen. This
will bring up a keypad which you can use to set any shutter angle between 5 and 360 degrees.
Use the manual shutter keypad to enter your shutter timing of
choice when shooting outdoors or under flicker free lights
Your URSA Mini has three shutter based auto exposure modes. To select one of these, tap the
'auto exposure' button in the far right of the shutter menu.
Shutter
This setting automatically adjusts shutter speed to maintain a constant exposure while
keeping iris aperture constant. If you want to maintain a fixed depth of field, this is the
setting to choose. It’s worth mentioning that the subtle automatic adjustments of the
shutter may have an effect on motion blur. It’s also worth keeping an eye out for any
flicker that may be introduced from various light fixtures on indoor shoots. URSA Mini’s
auto iris feature is not available when the ‘shutter’ auto exposure mode is selected.
S Iris
Maintains the correct exposure levels by adjusting the shutter, then the aperture. If the
maximum or minimum available shutter speed is reached and exposure still cannot be
maintained, URSA Mini will begin adjusting the aperture to keep exposure constant.
Iris + Shutter
Maintains the correct exposure levels by adjusting the aperture, then the shutter speed.
If the maximum or minimum available aperture is reached and exposure still cannot be
maintained, URSA Mini will begin adjusting the shutter speed to keep
exposure constant.
While in the shutter menu, tap 'auto exposure' to
access shutter based auto exposure modes
TIP When an auto exposure mode that effects the shutter is enabled, a small “A” will
appear next to the shutter angle indicator at the top of your URSA Mini touchscreen.
