Digital
Camera: Layers
Layers in digital
camera photography offers a new set of creative possibilites for
controlling the resulting image. If you were to create a stack of
images all exactly the same each image in the stack would be a layer.
To see parts
from the images near and at the bottom of the stack, pieces need
to be cut out of each layer above. If a change is made to an image
below an image that has no piece out of it, the change in the lower
image cannot be seen through the solid top image.
Whatever is
changed from the top layer down always affects the images beneath
it. Adjustment Layers is simply instructions. It allows adjustments
to the photo on top without changing the underlying layers.
Layers in digital
camera photography allows for broader creativity.
