Gaussian Blur effect
The Gaussian Blur effect blurs and softens the image and eliminates noise. The quality setting of the layer doesn’t affect Gaussian Blur.

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

Lens Blur effect
The Lens Blur effect simulates the blurring of objects not in the focal plane of a camera. The appearance of the blur depends on the control layer
used as a depth map and the iris settings for the simulated camera aperture.
In After Effects CS5.5 and later, the Lens Blur effect has been replaced by the Camera Lens Blur effect. (See
Camera Lens Blur effect (CS5.5)
.)

that demonstrates how to use the Lens Blur effect to create the look of a
shallow depth of field.
This effect works with 8-bpc and 16-bpc color.
Original (upper-left), Depth Map layer (lower-left), and result (lower-right)
The control layer from which the depth map is taken.
The channel of the control layer to use as the depth map. Pixels with low values correspond to low depth (near the
camera); pixels with high values correspond to high depth (far from the camera). Select Invert Depth Map to invert this relationship.
Depth of the focal plane, where pixels are in focus.
