Hi :-
I recently created an image in povray, a nebula type image of the orion
galaxy. In photoshop one of the filters allows you to radial blur an image.
Is there a way to create a radial blur similar to that in photoshop except
this time i would only be using Pov-Ray. And out of this nebula i would like
to create streaming light rays for this final effect, would i have to use
media for this and there aren't any tutorials on media in the pov-ray help
file. Is it possible to do this?
Thanks in advance :-)

Might be an idea to post your original image and the post-proc. image to
binaries.images so we can see exactly what you're after.
As for the media, you'll need to use scattering media - something like:
media{
method 3
intervals 10
samples 3,10
scattering {1,0.025 extinction 1}
}
If it's too thick, reduce the 0.025 value; too thin, increase it.
Try and constrain the media to the area you want the rays to be visible in, by
placing it in a transparent container, rather than using global media, which is
'orribly slow.

Radial blur (the Zoom type) can be simulated quite well with media.
Create a box and fill it with media. For density, use the image mapped
using map_type 0. Now point your camera towards the thing and make use
of perspective to change the amount of "blur" (the wider the FOV, the
more blur). Voila :)
