You can download the current luminous bloom file from this thread:

It's not that easy. Imagine you are making the bloom effect in PhotoShop 
or Gimp, but instead of making the second (bloom) layer use additive 
layering, you are simply decreasing it's opacity and nothing else. The 
light areas of the image which are next to dark ones acquire a dark halo 
which bleeds out from the shadowed area. Does this make sense? Perhaps I 
should post an example image.

When I figure out how to do what I want, I will be able to release 
version five :)
