Image Editing Filters and Effects

Question 1

What does the 'Gaussian Blur' filter do?

Accepted Answer

Softens an image by averaging pixel values with a bell-curve-shaped kernel

Answer

Gaussian Blur smooths an image by blending each pixel with its neighbors using a Gaussian (bell curve) distribution.

Question 2

What is the 'Unsharp Mask' filter used for despite its confusing name?

Accepted Answer

Sharpening image edges by increasing contrast along edges

Answer

Unsharp Mask sharpens by boosting the contrast along edge transitions, derived from a traditional darkroom technique using a blurred (unsharp) negative.

Question 3

What does the 'Camera Raw Filter' allow you to do non-destructively in Photoshop?

Accepted Answer

Apply RAW-style tonal, color, and detail adjustments to any layer

Answer

Camera Raw Filter gives you access to all Adobe Camera Raw controls — exposure, color, sharpening, noise reduction — directly on any Photoshop layer.

Question 4

Which Photoshop filter creates a high-contrast grayscale version of an image useful for sharpening via Overlay blend mode?

Accepted Answer

High Pass

Answer

High Pass extracts edge detail and renders everything else as 50% gray, which when set to Overlay sharpen only the edges.

Question 5

What effect does the 'Radial Blur' filter create?

Accepted Answer

A zoom or spin blur effect radiating from a center point

Answer

Radial Blur creates either a spin (rotation around a center point) or zoom (motion exploding from a center) blur effect.
