Illustrated Photoshop built-in filter 4: Blur

Filter Fourth Group: Blur ( Blurred )

Blur (blur) filters are used to soften a selection or image, and to dilute the boundaries of different colors in an image to mask the defect or create special effects.

　　1, Motion Blur ( dynamic blur filter )

　　function: blur the image in the specified direction (-360 degrees to +360 degrees) to the specified strength (1 to 999).

　　Adjust parameters:

　　angle: Sets the angle of the blur.

　　Distance: Set the intensity of motion blur.

　　Graphic effect:

Dynamic blur effect of original image

　　2, Gaussian Blur ( Gaussian blur filter )

　　function: quickly blur the selected part of the image by the specified value, resulting in a hazy effect.

　　Adjust parameters:

　　radius: Adjust the blur radius, the range is 0. 1 to 250 pixels.

　　Graphic effect:

Gaussian blur effect of original image
3, Blur (Fuzzy filter)

　　function: produces slight blur effect, can eliminate the noise in the image, if only apply once the effect is not obvious, can repeat application.

　　Tuning Parameters: None

　　Graphic effect:

　　4, Blur more ( further blur filter )

　　effect: The resulting blur effect is 3 to 4 times times the Blur filter effect, which can be compared with the above figure.

　　Tuning Parameters: None

5, Radial Blur (radial blur filter)　

Function: Simulates the blurring of a camera that moves or rotates.

Adjust parameters:

Quantity: Controls the intensity of the blur, ranging from 1 to 100.

Rotate: Blur along concentric circles at the specified rotation angle.

Scaling: Creates a blur effect that emits from the center point of an image to the perimeter.

Quality: There are three kinds of quality sketches, good, best, the effect from bad to good.

Graphic effect:

Rotation effect of original image

Zoom effect

6, Smart Blur (special blur filter)

Function: can produce a variety of fuzzy effects, so that the level of image weakening.

Adjust parameters:

Radius: Determines the distance to blur the filter.

Threshold: Determines what value the difference between pixels can be achieved by eliminating it.

Quality: can choose High, medium, low three kinds of quality.

Normal: This mode only blurs the image.

Edge Preference: This pattern outlines the color boundaries of the image.

Overlay Edge: The superposition effect of the first two modes.

Graphic effect:
