The roundness of the edges of the iris.

The rotation of the iris.

The size of the iris. Increase this value for greater blur.

All pixels with a brightness value greater than Specular Threshold are treated as specular highlights.

Film grain and noise are removed when you blur an image. To make the image look more realistic, you may want to add noise

back to the image so that it doesn’t look retouched. To add noise, set Noise Amount, and choose a noise type from the Noise Distribution menu.
To add noise without affecting the color in your image, choose Monochromatic Noise.

Stretches the control layer to the dimensions of the layer to which it is applied; otherwise, the control layer is centered on the

affected layer.

Radial Blur effect

The Radial Blur effect creates blurs around a point, simulating the result of a zooming or rotating camera.

You can specify the level of anti-aliasing applied at Best quality; no anti-aliasing is applied at Draft quality. At Draft quality, the blur appears
somewhat grainy. You may prefer the draft results for special effects, but the grain may flicker on interlaced displays.

This effect works with 8-bpc, 16-bpc, and 32-bpc color.

Original (left), and with effect applied (right)

Spin blurs in arcs around the Center point, as if the camera were rotating; Amount specifies degrees of rotation. Zoom blurs radially outward

from the center point; Amount specifies the length of the blur.

Reduce Interlace Flicker effect

The Reduce Interlace Flicker effect reduces high vertical frequencies to make images more suitable for use in an interlaced medium (such as
NTSC video). For example, images with thin horizontal lines can flicker when broadcast. Reduce Interlace Flicker applies a vertical directional blur
to soften horizontal edges to reduce the flickering.

This effect works with 8-bpc, 16-bpc, and 32-bpc color.

Flicker may result from fields that haven’t been separated.
