About Blurs

Blur is a graphical effect that aims to imitate an unfocused image. In a photography context blur can occur when the focal point of the lens is not at the right position of the target of the photograph. Also blur can have other origins. Blurs can happen as the result of a poor exposure during its recording (too long exposure time for a large movement of the object or a high movement of the recorder). Also blurring occurs when you use a very wide aperture (f4). In that case the objects that are out of focus are very blurred compared to the situation where the aperture is fully closed (f22).

In a graphical context, blurs are effects that imitate those situations (with more or less success).

Specific Parameters

The specific parameters for the Blur Layer are:

Size

The Size parameter controls how big the blur is. Depending on that value the blur can have different effects. Render time quickly increases as you increase the size parameter, so be careful.

This parameter is a compound value of two real numbers (x and y). Each indicates how big the blur is in its direction (x or y).

See the samples to get an idea of the variation of the sizes.

Types

There are 5 types of blur in synfig:

  • Motion Blur Layer a type of blur that aims to simulate a motion blur (the one that happens when the object's movement is too fast for the exposure time). It is controlled by a single parameter called "Aperture".
