Cave photos in UV and IR

Corehead

Well, it turns out that, last night, Zog the caveman also had a UV penlight (the kind used to detect counterfeit currency, not that cavemen HAD currency back then except for maybe some clams) and an infrared LASER. OOOOO!

Let's see how Zog fared with this stuff. But you know what? Zog really does need to "get a life" (or at least some mastadon steaks and fern ale)!

Zog used a beat-up old Canon A520, set at ISO 400...Aperture f 2.6...shutter speed 15 seconds..UV illum for 1 second AND laser IR "painted" oon the rock specimen for 14 seconds (digicams are generally not very sensitive to even laser IR illumination, with those darned IR cut filters anyhow).

Now Zog had some corn cobs laying around. Here's one with a 1-second UV illumination:

Zog wasn't really impressed with how that corn cob showed up under UV, so he tried his whiz-bang IR laser and "painted" the cob with it for 15 seconds:

Still not impressed, Zog decided on a 1-second UV illum AND 14-second IR laser painting.

I think Zog had a little too much of that fern ale he managed to find (and drink on an empty stomach--still no mastadon steaks to be had):

Hey there Corehead,

The laser on the corncob make it look like it's made out of stone.
Picks up a lot of detail doesn't it.... that's pretty cool.

Thanks for sharing .... Skippy
