| There are several ways to create the effect of depth of field.
This is one example. First you render the perspective view. |
 |
| Then perform a distance render. This will give you a
grayscale image similar to the one to the right. This grayscale representation makes
the objects close to the camera black in color and those furthest away white. The
objects in between are shades of gray.
The "distance render" is available in the render options. |
 |
| Open both pictures in PhotoShop.
These pictures should be the same size and from the same camera angle. |
 |
| Select the grayscale image. Then from the menu:
This copies the grayscale image into RAM so that you can use it later. |
 |
| Now select the perspective picture and create a new channel.
When you do this the only visible channel will be the new one you created. |
 |
| Now you simply paste the image from RAM into this channel. | |
 The image will appear in the new channel. Notice that the only channel visible is the "distance render" channel. This is expected. |
|
| Now apply the mask by click the "Load channel as
selection" button.
Doing this will apply a mask to the image based on the grayscale. |
 |
| It is necessary to make the perspective render visible again.
Simply click the "eye" out from your grayscale layer to turn it off, then
select the "eye" at the RGB layer to make it visible.
The mask is now affecting the perspective render. You can now apply any effect you want and it will be applied based on the grayscale mask. To achieve a Depth of field effect, you can use the Gaussian Blur filter which will blur objects furthest away more than those up close. Conversely, you could invert the mask and produce a motion blur. |
 |
 The image isn't a work of art, but it demonstrates the effect quite convincingly. Notice how the objects in the distance are blurred more than those that are near. This effect is called "depth of field" and is seen in many photographic images. |

This is not meant to be an all inclusive instruction on every possible way to have made the final image or produce the desired results. Bryce offers zillions of wonderful ways to replicate, multireplicate, reposition, etc. in its powerful interface. Experiment!
