Nikon CoolPix 2100 Infrared Sensitivity

	Camera: Nikon CoolPix 2100 Filter: none Exposure time: 1/327.80 F-stop: 5.2 ISO speed: 100 Focal length: 4.7000 White balance: Automatic EV: 13.1137
	Camera: Nikon CoolPix 2100 Filter: Heliopan 715nm IR pass filter Exposure time: 1/3 F-stop: 2.6 ISO speed: 277 Focal length: 4.7000 White Balance: Automatic EV: 2.8721 comments: Fairly insensitive as most modern cameras. But its high-ISO performance is really good for such a small camera. I guess it pays off that it is only 2MP, as this leaves the sensor elements rather large.
	Camera: Nikon CoolPix 2100 Filter: Heliopan 715nm IR pass filter Exposure time: 1/2.30 F-stop: 2.6 ISO speed: 400 Focal length: 4.7000 White Balance: Manual EV: 1.9587 comments: White balance on some leaves - pretty nice, but further decreases effective sensitivity.
The Nikon CoolPix does a pretty impressive job in IR. It's metering is ok in IR, and its white balance is pretty powerful so you can create rather good IR shots - with a tripod.

What is really good to see here is the influence of white balance in colour channel sensitivity. The visible light shot has a rather even distribution. The standard 715nm image has much stronger red channel compared to blue and green. By white balancing on IR-white leaves, the camera is set to an even RGB distribution again. Apparently, overall sensitivity is decreased, as was noted in similar cases by other people and myself.
