Hi all,
Before I left my inverse truchet tile done with sphere sweeps, I thought I'd
put a bunch of them in a scene and try my hand at focal blur. It didn't
quite get the feeling of depth I'd hoped for: I set the focal point to be
the central object (with a blue light), however I now think I should have
focused on something in the foreground. On the other hand perhaps I just
needed to crank up the aperture to place more emphasis on the depth of
field.
Would anyone like to offer an opinion on how I would best increase the
feeling of depth in the image?

Hmm. I would look at composition first, before any effects. As the 'wrong
image' shows, when you let things fall out the ends of the image,
especially the corners, that gives a much more effective illusion. All your
little knots are the same size and gathered right in the center of the
image. Place some way-far-off, and a few right up in the camera view, and
then you can use the same apeture to get a good clear DOF. If you keep the
up-close ones out of the center of the camera, you will naturally get some
interesting lines that lead the eye deeper in the image. If you like one,
you can accentuate it by placing another knot on the line.
If you are going to place your focus on the center, make it a warm-colored
knot - again, leads the eye. You could, as you say, place the focus
elsewhere - I think, however, that that will be an artistic choice rather
than a... um... psycho-optical one(?)
Anyway, cool image.

5TF!

Keep the current knot of sphere-sweeps. Keep the background. Keep the red
flouruscent sphere fog. But add more sphere-sweeps somewhere behind the
current one, like more "arms" go away towards the back. And those arms have
to be influenced by the backgound blue-black. Do you understand what I mean?
Ask me if you need more information.

Thanks for the tips mate, I agree with nearly everything you said. I had
another crack at it and I think this one is an improvement.

Sweet... perhaps they are a species of airborne plankton drifting in the
atmosphere of a warm sub-Jovian gas giant!
See you in Khyberspace!
