Exposure (cont'd)

• Use Auto Exposure:
As the name implies, auto exposure automatically changes exposure in order
to maintain a medium, optimum exposure in which the maximum amount of details are shown. If
lighting conditions in the room or on the subject are changing, or if the subject emits its own varying
amount of light (as with an LCD screen), you might consider auto exposure.
Automatic exposure adjustment depends upon two things: the EXP (Exposure Value, from 1 to
15), and the actual brightness/darkness of the subject.
Exposure Value –
Auto exposure with an EXP setting of 10 will always be brighter than auto
exposure with an EXP setting of 8, for one example.
Actual brightness/darkness –
Auto exposure will react to changes in actual brightness/
darkness. With auto exposure on, if you are capturing a bright iPad screen and it dims, the
Ziggi-HD will adjust exposure to brighten the image. If the screen brightens again, Ziggi-HD
will adjust exposure to darken the image.
• To Turn on Auto Exposure:
Click the Auto tab in the Presenter software, and select “On.” The sun icon
next to Auto will turn green. Ziggi-HD will now constantly determine the optimal exposure for your
image, and may adjust exposure at any time.
Note: Auto exposure should be turned to “Off” for stop-motion animation projects, which rely upon
uniform, consistent exposure.
