TIP
It is a good idea to have a few neutral-color gradient images handy for use as backgrounds
in these studio setups. For example, create an image with a gray gradient (from light gray to
dark gray is usually best). Experiment with gradient directions, too. The accompanying images
show some sample gradients that you could use. Always remember that a subtle gradient is
usually better than a stark one—for example, a white-to-black gradient or a gradient between
two primary colors.
If you intend to use this gradient as a “wraparound” spherical background (discussed later),
make sure the gradient is oriented perfectly vertical.

Backdrop Images in Your Model
If you need the ability to realistically move the view (or the camera) through the scene
and have the background adjust accordingly (in what is called a parallax shift), a good
approach is to set up your model as a studio scene with a backdrop. This usually gives
you more control in the appearance of the background than if you applied a background
image as an environment or sky image. Figure 5.32 illustrates this setup.
