An awfully bright sunny summers days in Fiordland national park and no clouds to help diffuse the light, no clouds! in Fiordland!!! its not a common occurance.
Are you using any specific filter to cut through the reflection on the surface of the water. The color and detail of the underwater rocks are excellent. Can you recommend any favorite filter brands?
Thanks I'm just using a Hoya circular polarizer at the moment it always help to take away any reflections/glare off surfaces like water and allow you to see through it, also takes the shine off plants too
