I bought an infrared filter at the photokina and am heavily testing it. So, I found a good way to use my old D100. As I never wrote anything again, here a small update. During porijazz, my camera got wet and I couldn’t take pictures of the first day. Luckily that happened shortly before my birthday and my parents could give me some money to buy a D200, which is anyway far better than the old one and a necessary tool to work (faster, bigger, better, bla bla bla).The nice thing is now, that obviously my old camera is such a crap (lightmeter wise and other issues, when comparing it to the newer models) that it has the huge advantage of having a bad filter in front of the chip. And that means, that it actually detects infrared light (and far better than the newer cameras). I can thus just work with normal ISO at a normal shutter speed and take pictures. See yourself, there are more to come.
