Default Fluorescent Mineral

Hi, this is my first posting. Just got my Rebel XT a couple of days ago and have been trying to figure out all the buttons...
Here is a shot of a fluorscent mineral under shortwave UV light and also incandescent light.

wow, that is really interesting how that light affects that mineral. So is that how you actually saw that mineral with your eyes as well?

Hi, Yes that is how the rock actually looked under shortwave UV. Most of these rocks you would just pass over in natural light, but under long or shortwave UV they do wonderful things...

Do you have to wear protective eyewear when using those lights?

You do for the shortwave UV but not the longwave UV (blacklight).
It's interesting just how much plastic and glass block UV light. In the photo below, on the left is a plastic cover from a CD case and on the right the UV safety glasses. The shortwave UV light is off to the right and low shooting onto the rock. You can see the shortwave UV light reflected in the safety glasses. One interesting note, all of these photos were shot through a UV Haze filter
f4.5 1/4sec ISO400

About as basic as you can get. The UV shots were done in darkness with a handheld Superbright 2000 UV light about 12 inches from the mineral. The incandescent shots where done by just turning on the room light (2 or 3 60W bulbs overhead).
