Riechert • Jung Model #1177 (dual fiber optic outputs stereo microscope light) run at approximately 80 watts, Nikkor 105 mm Micro, Nikon D200, White Balance – Incandescent, No Flash, Shutter Speed 1/30 s, f-stop 7.1, set on a Bogen 190PROB tripod system.
This quick project was put together in response to a recent discussion with another Panoramio User to try and illustrate the visual effects of doing something as simple as wetting a subject (in this case rocks, minerals, and fossils) can change effectively what the camera sees in details and color saturations.
I will leave this up for a while as there seems to be a little interest in viewing this.
Thanks – Tom Askew (HazMat @ Panoramio)
Hey there Tom,
Nice job. I had a difficult time trying to get my stones to capture correctly! I have noticed that it is polished surfaces as well that appear to look wet and will show a great aspect of color saturation. I will certainly look for some microscope lighting in the future. As for now, I will be stuck with the equipment available to me and will struggle to keep up quality.
Memphismike...The binocular lab lights are nice in the sense that you can control the amount of light and with the fiber optic Outputs you can control where, how, and the angle of the lighting. Just remember to set your white balance to compensate for the type of lamp used in them or you may get some other weird off colors from the light itself.
Haven't forgotten about your other UFO. The info you provided tells a lot of what it is not. I'll do a little more research on green minerals (most likely either Fe or Cu giving it the green coloring with a slight chance of Cr or Ni).
Glad you enjoyed the demo. Sometimes it is easier to "show" than to "explain". I was trying to get the point across that the water acts like a polished surface sometimes infilling the minute scratches and uneven surface to refract and reflect the light a little different.
Thank you again for the info.
Added info on UFO "through a small powered magnification the green strands appear to be condensed plant like material. On the polished surface at top you can look down into this piece and it will appear to look like veins or tunnels in an almost honeycomb fashion. Only one of the three curators who have got to actually hand hold this piece slightly suggested it a limb cast of extinct species and then dismissed the idea for some reason."
I will do my best to invest in some mineral and gem test equipment or find resources locally and see if I can find anything more about it. Would you be interested in some gamma ray test results? Is there an accurate test I might be able to do to help solve the mystery in this piece?
Thank you again,
