We don't have that many rocks in our country. Still, I came across some - albeit in a park.

Beautiful image - the ladder adds the human touch and a bit of mystery.

You are absolutelly right, Renato, that ladder, seems like going nowhere....

It's been rather a long time since I shot this (eight years, I think); I'm getting back to large format, as and when I can regain control of my darkroom and have the time to shoot and process and money for materials. Graphic View (first version, with non-centered tilts), Componon 150 mm, on Arista .EDU Ultra (Fomapan) 100, processed in Parodinal 1:50. I don't recall the exposure details and don't have them recorded with the scan, but I can see that I was able to stop down enough to get some water movement.

This was shot in the Smokies, near the Appalachian Trail and Smokey Mountains Parkway, with a rather precarious tripod setup that put the camera out beyond the wall that separates tourists from the river bed. Focusing and composing on the ground glass was a challenge.

Welcome back Donald.

A nice abstraction by Mother Nature.

I like the blurry whirlpool upper left!

The entire image seems to work as a "rule of thirds" illustration.

A bit of a different topic. This is calcite in its crystalline form. The smaller black spots are unknown to me but could be chalcopyrite and sphalerite.
This most likely came from southern Missouri or northern Arkansas. From my brothers collection.


Same crystal, different perspective.


Now for the hard part. 4 sec @ f45, TMX, d-76 1:1. The hard part is the lens. It is a Nikkor SW 4.5/90 with the rear element removed.
I haven't a clue on the focal length. Perhaps someone who knows can say. The lens is about 4 inches off the crystal with the bellows extended 170mm from focal plane to shutter.

I may try this one again as I was looking for an inner luminesce from the backlighting. I need a back cover cloth and some different angles.

nice Marty,

Theres some glow there. with that goal in mind i wonder how a dark background would be, maybe w/ a hole to allow backlighting =)

Reminds me of a lovely fluorite crystal I once saw - a beautiful pyramid.

Thanks Nicholas,
On the right side of the first image there is a face with relief from the formation process. I really would like to get that face with the inner luminesce and see if I can get some sort of light emanating from the riser portions of the stair step. You know this might be fluorite. Sadly, my brother passed nearly 2 years ago so I cannot ask. I have just a few samples from his collection. I plan to shoot these as well but they mostly are thumbnails sizes and may be difficult to get a good image with LF.

Oh, that should read 4 min not sec.
