# Edges

Diffusion can be influenced by light beyond the bounds of the image.

In some cases the default mode (Mirrored) can cause glints similar to a gate flare if a very bright source is near the edges of frame. If this behavior is not desirable the Blend property can be reduced or a different Mode can be selected.
