ACA Working with Layers and Selections Questions and Answers

Question 1

A designer wants to non-destructively remove the background of a portrait photograph to allow for easy refinements to the subject's hairline later. Which of the following methods is the most appropriate for this task?

Accepted Answer

Add a layer mask and paint with black to hide the background.

Answer

Using a layer mask is a non-destructive editing technique. Painting with black on the mask hides the pixels of that layer without permanently deleting them. This allows the designer to go back and refine the edge of the mask at any time by painting with white (to reveal) or black (to hide).

Question 2

Which of the following layer blending modes looks at the color information in each channel and multiplies the base color by the blend color, always resulting in a darker color?

Accepted Answer

Multiply

Answer

The Multiply blend mode multiplies the color values of the top layer's pixels with the pixels in the layer(s) below it. The result is always a darker color, as any color multiplied by black becomes black, and any color multiplied by white remains unchanged.

Question 3

You have spent a significant amount of time creating a complex selection of an object. To avoid having to recreate this selection if you deselect it, what is the best practice for storing it for future use within the same document?

Accepted Answer

Save the selection as an alpha channel.

Answer

Saving a selection creates an alpha channel, which is stored within the Channels panel of the Photoshop document. This channel can be loaded at any time to reactivate the exact same selection, preserving the work.

Question 4

A photo retoucher needs to make a precise selection around a model's hair, which has many fine, wispy strands against a detailed background. Which Photoshop workspace is specifically designed to refine such complex edges?

Accepted Answer

The Select and Mask workspace

Answer

The Select and Mask workspace provides a comprehensive set of tools, including the Refine Edge Brush, specifically for improving selections of complex subjects like hair and fur. It uses edge detection to intelligently differentiate between foreground and background details.

Question 5

What is the primary function of an adjustment layer in a layer-based editing program like Adobe Photoshop?

Accepted Answer

To apply non-destructive color and tonal adjustments to layers below it.

Answer

Adjustment layers apply color and tonal modifications without altering the original pixel data of the layers they affect. They sit on top of other layers and can be edited, masked, or have their opacity changed at any point, providing maximum flexibility.
