Blackmagic Design URSA Mini Manual De Instalación Y Funcionamiento página 84

Tapping the 'shutter' indicator brings up the suggested shutter values along the bottom of your
URSA Mini's touch screen. If you have auto exposure set to 'off,' this screen will show you your
currently selected shutter value, as well as the available flicker free shutter values, based on
the mains power frequency you have selected in your URSA Mini's 'setup' menu. For more
information, see the 'setup settings' section in this manual.
NOTE The characteristics of individual light sources may still cause flicker even when
using flicker free values. We recommend always performing a test shoot when not
using continuous lights.
To select one of the flicker free shutter values, simply tap on one of the displayed shutter
values. Tap the arrows on either side of the current shutter value indicator to cycle through
some of the most commonly used values.
Your URSA Mini will suggest flicker free shutter values based on the
mains power frequency you choose in the 'setup' menu
If you would like to choose a specific shutter value, you can do so by double tapping the current
shutter indicator at the bottom left of your screen. This opens a keypad that allows you to type
in any shutter value with up to two decimal places.
If you type in a shutter speed that is incompatible with your current frame rate, the nearest
achievable shutter speed will be used.
The manual shutter keypad allows you to type in any shutter value you wish
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 value 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.
