Thanks everyone.
These are shot in the Chichester State Forest (Outside Dungog, NSW) at Jerusalem Creek and Problem Creek.
pp was done in CS3 and was a combination of levels, velvia etc but the main softness comes from an action called Midnight. This one is a Midnight Gold and works particularly well on backlit subjects.
If you can't find it on-line, drop me a PM with your e-mail addy and i'll send it to you.
