Settings and Macros/EllipticalBlur Description

Creates elliptical blur effect with adjustable aspect and angle, so there is no need in pre/postscaling or auxiliary angular transformations of your source picture. There is also a possibility of creating squeezed zoom blur.

This tool may be especially useful to simulate fast spin of aircraft propellers and car wheels

Node Inputs

• Input

  Source image. Required.

  Power Map

  Map which alters the power of the effect. The brighter an area the stronger the blur. Optional.

  Effect Mask

  Defines the areas where the effect is applied. In contrast to Power Map it doesn't smoothly decrease the power of the effect, but blends with the original instead. Optional.

Controls Tab

  Lets you select between elliptical and zoom blur

  Speed

  Center

  Sets the center of the rotation/zoom

  Width

  Relative width

  Height

  Angle

  Motion Correction

  When the object is moving (Center is animated), circular and radial blurs affect areas to the different sides of the center unequally. This checkbox allows you take this effect into account

  Motion Correction Magnitude

  Adjusts the non-uniformity of motion blurs on moving objects

  Pre-Gamma / Post-Gamma

  Switches gamma treatment for sRGB images on and off

  Image Gamma

  Allows to achieve nice blooming effect in case you work with sRGB (not true linear) images. Increase the Image Gamma parameter to make highlights emphasis more noticeable

  Set Depth

  Sets the bit depth. It's recommended to use 32bit float with Pre-Gamma / Post-Gamma switched on.
