Using masks in Photoshop CS

What does using masks to select images enable you to do?

Control the precision of the edges of a selection
Define a selection based on color range
Delete background pixels from an image
Extract a foreground image element from its background



Which steps do you perform to extract an element from a photograph?

Apply a fill to the outlined image you want to extract
Draw a mask, place it over the image, and then use a crop tool to extract the image
Draw an extraction path around the image
Specify the color range of the image



Suppose you want to use the Background Eraser tool to select a foreground element in a photograph. What do you need to do to ensure that you mask only the background of the image?

Drag the circle - or brush - on the tool's cursor on the background only
Ensure that you drag the crosshair on the tool's cursor on the background only
Set the tool to use a large brush size
Specify the color range that the tool must mask




What effect does decreasing the fuzziness setting for a selection based on color range have?

It determines the resolution of the selection
It increases the color range and so decreases the sharpness of the edges of the selection
It restricts the color range and so sharpens the edges of the selection
