Apply 3d depth with the box blur

This tutorial is an extension of a previous tutorial

This next option is more ambitious and will create a better sense of depth.

Take the image we created in the previous tutorial and essentially what were going to do is to apply the box blur filter individual to each element to push them back in the depth of

field.

Identify where you want your focal plane to be, for this image, we'll make it this building.

This building will have no blur applied to it. Working your way forward and backwards apply the box blue to each element.

For example:

Select the sun layer and goto the box blur filter

You don't want to go above 10 pixels or the images just become mushy.

Now just start working your way forward apply the box blur to lessor amounts as you move to the

focal plane.

I adjusted the box blue by even numbers apply 8 6 4 2 and 0 amounts to each element as needed.

For those element forward of the focal plane, I applied 8 as my highest amount.

There is no hard and fast rules regarding this, it's all up to you and what looks good to you!

Once your happy then your done!
