Question about Olympus Camedia C-2100 Ultra Zoom Digital Camera
Does anyone have any experience with the Tiffen "Hot Mirror" filters on a digital camera? They are supposed to remove a significant amount of the infrared component of the light reaching the CCD, which, due to its extended sensitivity to infrared, can influence the color accuracy of a digital image.

The Tiffen hot mirror works fine on my D500. On some cameras it's not needed as the lens system already has some amount of IR filtering. When IR is present it causes some tinting of sky towards purple. The filter works as a mirror by reflecting the 800 - 1100 nanometer wavelengths. This is the range that causes the problem. I wouldn't just buy one without determining if the camera really needs it. Mine may not need it in most cases but many of my pictures come from the Arctic and there's no way to do some over again. I had a real problem with a previous Casio so I didn't want to take any chances.
