The Finnish Caving Association was having a course on basic caving. I've been on that course... but it seemed like a fun thing to do and a nice visit to Turku. And I ended up doing more practice with cave photography using multiple flashes and radio triggers.
My previous attempt was not entirely successful, the back light not being very visible. I think I got the idea now, having increased the flash level on the back flash -- even on a small area and with just half a meter, I used 1/4 or 1/2 flash output on a Nikon SB-910, and the front/side flash was set at 1/8 on a Nikon SB-25. For bigger spaces I may actually need more powerful equipment.
Looking forward to trying this out even further.
I was also inspired by two other things on this trip, first off, fed up with garbage on the cave sites, I decided to bring all that I could find back to a trash can and do it on all my future caving trips as well. And secondly, we got to witness Dare Talvitie's new book's (Valkea Liekki) release event. Looking forward to reading it!
Here is Ralf and Jukka holding lectures:
Here are some of the pictures taking with the multiple flash setup:
And here we are practising chimney technique on the crack next to the cave. And Ralf levitating.

Grand Canyon National Park — Biologists were shocked, and a little disturbed, Thursday after a rafting party in the Grand Canyon reported the first-ever confirmed sighting of the elusive, often-rumored, Flaming Land Shark. Up until Thursday's discovery, numerous rafting parties had reported sightings of the rare species, but none had captured photographic evidence documenting the elusive, drunken animal in its native habitat.
