Blur effects

There are 4 Blur effects in Corel Vector, including:

  3. Tilt shift
  4. Zoom Blur

Blur Effect

The Blur effect applies a Gaussian blur to the object.

Gaussian Blur

The Gaussian blur produces a hazy effect, blurring the focus of an image according to Gaussian distribution, which spreads the pixel information outward using bell-shaped curves.

It is by far the most popular blur effect, and is used by thousands of photographers and designers on daily basis to smooth the edges of the mask, as well as reduce noise and details.

Gaussian blur effect controls

You can use the Radius (1) slider to control the intensity of the effect.

And then, use the Clip (2) radio slider to prevent the blur from overflowing the image.

Lens blur

Lens blur effect

The Lens blur effect adds depth to the object by blurring objects in the background without impacting the objects in the foreground.

For example, you can simulate a telephoto effect by using lens blur. Corel Vector provides several controls to fine-tune the effect:

Lens blur effect

  1. the Radius (1) slider controls the intensity of the effect
  2. the Brightness (2) slider can brighten up or dim the image
  3. the Angle (3) slider controls the distribution of the effect. Every lens focuses on the object by a specific angle, which lets you imitate a real camera lens effect.

Tilt shift

The Tilt shift effect applies partial or areal smoothing to the image. It allows you to selectively blur some regions of the image while maintaining the focal points.

Tilt shift effect

Opposite to the lens blur, the Tilt shift is a linear effect so you can literally move the blur back and forth. This flexibility is secured by the comprehensive system of the six sliders:

tilt and shift controls

  1. the Start X slider sets a starting point of the blur on the X-axis
  2. the Start Y slider sets a starting point of the effect on the Y axis
  3. the End X slider sets an ending point on the X-axis
  4. the End Y slider sets an ending point on the Y-axis
  5. the Blur Radius controls the intensity of the blur
  6. the Gradient Radius helps you to define the size of the focal point.

Zoom blur

The Zoom blur effect simulates the lens zoom burst when the blurry lines are bursting out of the photo.

By default, the blurry lines emanate from the center to the sides. You can change horizontal distribution by dragging the Center X (1) slider; and vertical distribution by dragging the Center Y (2) slider.

The Strength (3) slider controls the intensity of the effect.
