Filter layer

The Filter layer includes various blur effects and sharpness. The Filter layer can be masked like any other layer, allowing for effects such as fake bokeh. To blur with a box blur, a Gaussian blur or a disc blur, or to sharpen, first select the desired operation from the dropdown menu and then drag the slider to the right for more effect and left for less effect.

Blur Filter RGB and HSL Per-Channel Options

Here you can blur the red, green and blue channels individually. Additionally, you can also get other interesting artistic effects with filtering individual colour, saturation, or brightness channels of an image as well. For example, channel blurs can be used to create halation effects that are similar to the popular home movie tape or VHS look.
