The first trip out with the NEX-3 Underground.

A Massive thanks to PeterQD for lending me an M42-NEX adaptor.

All shot with a Pentacon 30/3.5, between f3.5 and f8. ISO varied between 400 and 3200. I'll probably try to keep it below 1600 in the future.

Beautiful pictures and you worked out the lighting perfectly. You have my real admiration for doing that - I'm claustrophobic and even the thought of being down in that hole makes me start to quiver.

No way would I go in there. Your pics are enough for me. Laughing

These are amazing...can you explain what some of the colors represent in the rocks ie is it just through water staining?

Never been in a mine like this. Beautiful.
Thanks to bring me there Smile

The colours are caused by mineralisation in the water flowing over the walls. The white is Calcite, the orange is Iron. There's Oil Shales present in parts of the mine too, which are a dark brown. By far the most decorated mine I know of. It usually takes thousands of years in a cave to start to get this kind of colour underground, this has happened in under a century.

The size of the stopes (mined out areas), are huge compared to most metalliferous mines. Chambers in slate mines are easily this big, (and often far, far bigger), but mostly grey/black and more uniform.

What impressive colors!! Guess it wasn't easy to light that...

A couple more.

Just a note - I am terrified (In the literal sense of the word) of heights. There are some big drops in here (The abseil is 120ft, and the drop down the big stope from where I am standing is 50-60ft). If I can do this, anyone can, it's more about common sense and minimising risks, and less to do with having a large set of testicles.

Anyway, Pictures...

How weird! You'd never get me down that mine, but I have no fear of heights at all - I've done climbing, abseiling and gliding in my time. And don't ask me about ladders and scaffolding! We'd make a great team! Smile

What is the basic rock containing the zinc ore? If it's slate I'm quite surprised so much water can percolate though it.

It's not Slate, although in a Slate mine, water does get through, sometimes in great quantities. I think it's normal Country Rock, albeit with very large veins in it. It's actually hard to tell underneath all the Calcite that is over it.

Thanks for the explanation,I don't know if I would ever go in a mine like that,I appreciate the fact you do and take these amazing pictures...the minerals/colors remind me of the volcanic parts of NZ ie Rotorua and the minerals that can be seen around geysers.

I've been several times in mines, natural caves and old bunkers, but not a single one looked so dangerous Smile Stunning

Which flash did you use? / How did you light that?


Bye the way NEX-3 and 5 are nice till ISO1600, for a comparable nice ISO3200 you need the newer sensor from NEX-5N/C3 or upwards
