Francois, I suppose you used neutral grey gradual filters, but also yellow, orange or red?
And picture 12 foreground has very nice metamorphic rocks (my other "hobby"). Where was that photo taken?

Hans Yes, 100x ND and mainly red and yellow filtering. The metamorphic rocks were at Abel Tasman (when we got back from Apple Tree Bay) southern island New Zealand. Have you ever seen the moeraki boulders? |

These boulders are quite something diffrent than metamorphic rocks as they consist of mud, fine silt and clay, cemented by calcite that has formed them on the bottom of the ocean over a period of millions of years.Now due to erosion of the coasts they become exposed. When i saw them in real life they( especially the broken ones) looked a lot like the septarian samples i've seen on diffrent occasions, as a matter of fact these are a form of giant septarian rocks. They don't seem to be unique to New Zealand as others are found in diffrent places around the world.    |

Have you ever seen the moeraki boulders? No, but these are truly impressive boulders! They erode like granite boulders, that is, peeling of the outer layers. I've never seen them in this size. They are huge! I suppose they are cousins from the manganese nodules you can find in the red sea. But in general those are small size only. Hans |

Basalt colums at the black beach, Vik, Iceland  One could wonder just how much the architect of the cathedral in Reykjavik was influenced by the basalt colums?  The little church in Vik, Iceland.  |
