TIP The following is a key to the main scales to which you should shoot. A) Tight: Close-up shot, approximately from the chest up B) Medium: Medium-distance shot, approximately from the waist up C) Wide: Wide-angle, full-body shot, with space above and below the subject If the subject is a person who's standing or sitting and won't move much or gesture widely, try shooting with the camera turned sideways to make maximum use of the camera's resolution. Always shoot the subject centered within the frame laterally-or at least not cropped on either side. If the subject is partially out of the frame in the composited layout, it's easy to move the layer to the side. Conversely, if you crop an arm at the shoulder while shooting and later decide that you want to position the subject more toward the center frame than you anticipated, you can't put the arm back in the frame. Optimizing the color screen backdrop A high-quality color backdrop that is properly lit yields superior results. There are several aspects to a good backdrop. Color and finish: Adobe recommends green as the best backdrop color for typical Ultra usage. In some cases, however, green isn't the best backdrop color, and other colors will work. For example, if your subject must wear green clothing, you may get better results with a blue screen. In general, the best key color is a color that is not used in your subject. If you use key color paint, apply several coats and allow adequate drying time to increase color saturation. If you use an improvised backdrop material, ensure that the color is deeply saturated and that the surface has a smooth matte finish. Avoid shiny or textured surfaces. Flatness: If you use a cloth or plastic sheeting, reduce the wrinkles as much as possible. A hand-held clothes steamer can be helpful. For a free-hanging cloth, stretch it tight enough to remove the folds and prevent rippling from air currents. You can use the elastic straps with clips designed for holding bedsheets to mattresses for this purpose. 60 How to

How to
The following is a key to the main scales to which you should shoot.
A) Tight: Close-up shot, approximately from the chest up B) Medium: Medium-distance shot,
approximately from the waist up C) Wide: Wide-angle, full-body shot, with space above and below
the subject
Always shoot the subject centered within the frame laterally—or at least not cropped on either
side. If the subject is partially out of the frame in the composited layout, it’s easy to move the
layer to the side. Conversely, if you crop an arm at the shoulder while shooting and later
decide that you want to position the subject more toward the center frame than you
anticipated, you can’t put the arm back in the frame.
Optimizing the color screen backdrop
A high-quality color backdrop that is properly lit yields superior results. There are several
aspects to a good backdrop.
Color and finish:
Adobe recommends green as the best backdrop color for typical Ultra usage.
In some cases, however, green isn’t the best backdrop color, and other colors will work. For
example, if your subject must wear green clothing, you may get better results with a blue
screen. In general, the best key color is a color that is not used in your subject. If you use key
color paint, apply several coats and allow adequate drying time to increase color saturation. If
you use an improvised backdrop material, ensure that the color is deeply saturated and that
the surface has a smooth matte finish. Avoid shiny or textured surfaces.
Flatness:
If you use a cloth or plastic sheeting, reduce the wrinkles as much as possible. A
hand-held clothes steamer can be helpful. For a free-hanging cloth, stretch it tight enough to
remove the folds and prevent rippling from air currents. You can use the elastic straps with
clips designed for holding bedsheets to mattresses for this purpose.
TIP
If the subject is a person who’s standing or sitting and won’t move much or gesture
widely, try shooting with the camera turned sideways to make maximum use of the
camera’s resolution.
