How do I accomplish a similar effect?

I’m trying to figure out how to do this effect:

Any suggestions?

Hi,

You could probably achieve something similar with a combination of BCC Caustics and BCC Fast Film Glow filters, then perhaps the BCC Fast Film Process filter for the day to night look. Hard to tell what’s happening with the centerpiece from a still image though.

I hope this helps!

Cheers,

Peter.
