Boyden Cavern

First time taking images inside a cave. I was the only one on the tour so the guide agreed to turn all of the lights off and just use our flash lights. The Lumix was set for flash with an ISO of 2500, my first problem was without any lights no AF, the second problem was the 14-140mm lens and the tight quarters. Solved the first by using my flash light to get the AF to work and then in PS removed the flash light circle with fill content aware. Anyone else have any experience shooting in a cave without the aid of slave lights etc.?

If you enlarge image #6 you will see what appears to be dust spots, but in fact the whole cave has calcium crystals that pick up any reflected light. Quite impressive.

Dan, doesn't the GH2 have a focus-assist lamp? --WT

Yes, it does, but in complete darkness, it does not have enough brightness to trigger AF.

When we used to shoot wedding parties in dark churches, we used a flashlight to assist our manual focusing on the Hasselblads :).
