Apply the Card Wipe effect to the Photos.psd layer in the Card
Wipe Photos comp. Then take both the Rows value and the
Columns value to 6, to correspond to the grid I created in the
Photoshop document. Because the two grids match (the Card
Wipe grid and the PSD grid), the pictures appear to all be sepa-
rate cards now (Fig. 20.13 ).
So, technically, we've already created the 3D postcard effect.
But what really enhances this is taking the Transition Completion
value to 0%, then increasing Z Jitter Amount (in the Position Jitter
area at the bottom of the effect's options in the Effect Controls
panel), and reducing the Z Jitter Speed value to 0, so they don't
fl uctuate forwards and backwards. Then you are free to animate
the camera position to navigate through the “postcards” to cre-
ate an interesting animation. This effect is seen often in National
Geographic shows and travel related TV programs. In the 3D
Postcards comp, I've added a comp camera, a comp light, and
some animation (Fig. 20.14 ).
You might notice
that this is a
created from a colossal
PSD fi le. When creating
PSD fi les to be used as
3D postcards, you might
want to consider creating
images much larger than
necessary (this PSD fi le
is 3600 pixels wide).
Similarly, when you zoom
your camera in and
around these images, they
still maintain their quality.
