The massive rock in the top 1/3 of the image is the Hartselle Formation. The eroded, dissolved, and narrow, fluted Monteagle Limestone is seen in the lower part of the image. Both are Mississippian in geologic age. Caver in the background for scale.

There are multiple lighting options available with the flashlight’s 3-way switch: the front light alone, both front and lower lights, and lower lights only.
Each of these shots contains a Gretag-Macbeth Color Checker classic (http://www.xrite.com/product_overview.aspx?ID=820) which is "an array of 24 scientifically prepared natural, chromatic, primary and gray scale colored squares in a wide range of colors. Many of the squares represent natural objects, such as human skin, foliage and blue sky. Since they exemplify the color of their counterparts and reflect light the same way in all parts of the visible spectrum, the squares will match the colors of representative sample natural objects under any illumination, and with any color reproduction process."

High on the success of getting the switch working, I decided to press on.
Next up, I soldered the 6V bulb to the leads: Another continuity/resistance test, and still looking good - Hey "test as you go" works wonders if you can mange it.
For strobist: Testing new Ebay triggers (received yesterday) with DigiSlave 3000 firing into umbrella high above and slightly to right. F8 @ 1 second (ISO 50) with ND filter on to allow for slow enough shutter speed to show light on. Triggers work great. Gonna have to point flash a people soon!
