What sort of colour effects can you do using this filter? This one strikes me as having considerable colour potential, say white or yellow against blue.

Creative and unique. Well done.

Really appreciating this Helios series - looks like you're developing reliable techniques for expressing the swirl.

Those bubbles are almost intimidating here - but the boldness of the red holds them at bay.

... continuing ... but managed to include all the little spray streaks around it.

This one's a beauty too! You've exploited that big centre brightness so well.

A blinder. Love it.

I guess you're experimenting with distances - I prefer the swirl here with the flowers of IMG4595 - can you manage that ?

Those bubbles look great within the pale mauve.
