Hey,
I've been trying to achieve a 'blurry-light-bubbles' effect that you see i.e. on macros, or in photos of night city-lights.. It's kind of hard to explain, I'll better just drop some examples:



Mainly, I wanna achieve that blurry effect that you get to see with your very-own eyes when you almost close your eyes, or well, when you see those photos with special lenses.

I hope you can give me a hand.
Please note, there can be no brushes involved, everything must be done through Photoshop filters, gradients, whatever (i.e. Filter > Blur > ... but no brushing or erasing) - this is because I want to create an action from these steps.
