5 Color Correction - Independently adjust brightness, color, contrast and saturation for
the different layers in your composite to increase their realistic blend. It's best to make
color, brightness and saturation changes to the foreground image using Ultimatte's
color correction settings rather than changing camera settings such as lens aperture.
This is because any change to the camera will also affect the key.
6 Additional Background and Layer Settings - Use the additional background and layer
settings to add elements such as lighting effects to your composition. For example, you
can create spotlight effects that shine down on you talent by using an image connected
to the layer input that is designed for a spotlight effect. You can then blend that image
into the foreground layer.
7 Additional Matte Input Settings - Add additional mattes to your composition,
for example a garbage matte to remove unwanted foreground elements from your
composition, or a hold out matte to tell Ultimatte to ignore areas of the foreground you
don't want to key. You can build a rough window using Ultimatte's 'window' controls in
the matte input settings, or assign a custom matte image loaded in the media pool for
more precision.
There are many more advanced settings and tools you can use to improve the mattes,
strengthen the key, blend layers and generally build and finesse your final composite.
Details on how to use all the tools are provided throughout the rest of this manual so
you can explore your Ultimatte with confidence.
