hi guys! every chance i get, i'm shooting in infrared, exploring, discovering, and having lots of fun doing it! it sure is THRILLING to explore the world this way!!! kemal and i have done a lot of reading about shooting infrared with our cams, and we're just experimenting. it's been frustrating seeing the results. We've found out why our images don't look the way we think IR images should look. every digital camera microchip (CCD or CMOS) has the ability to see in infrared, as well as in the visible part of the light spectrum. So digital cam manufacturers put internal filters to remove the IR part in order to get more accurate and natural colors. Some Sony model digital cams and camcorders (F-717, F-707, F-828 are the camera models for example) can move this filter out of the way and this mode is known as night vision or night shot. Since certain materials tend to become partially transparent (clothing), Sony removed manual controls in this mode which makes DAY infrared shots over-exposed. The only way to control this and get a normal shot is to reduce the amount of light and that's why we're using neutral density filters when we're shooting infrared. it's frustrating because because the shutter speed is FIXED...1/60th of a second. Also when you shoot in this mode, you can't manually focus. Arrrrgggg! a lot of people who, for example, upgrade from F-707 to better Sony models turn their 707 into a full-time infrared camera by removing (physically) the internal infrared filter (hot-mirror). Then you replace that hot-mirror with a regular piece of glass (same or close-to-the same thickness). this will allow them to have full control in manual mode, and you can shoot EVERYTHING in IR, focus manually, and shoot on ANY shutter speed with AMAZING results! We plan to eventually turn our F-717 into an infrared cam so we have more control. The other way to take IR images with our cam is to use our IR filter that we purchased. But the problem with this is that the hot-mirror is CUTTING OUT almost all the infrared part, and then you have external IR filter which cuts off almost all visible part of the spectrum, and what you have leftover is just a narrow window of IR light. They're not pure IR images. Anyway, we want to shoot PURE infrared images, and we just can't do that with our digital cams until we PHYSICALLY modify our camera. Once we do that, we will be able to take some INCREDIBLE infrared images because when we shoot, we will be capturing the ENTIRE infrared spectrum and not just a part of it!!!!!!! Check out this gallery guys. Don Ellis' IR images are made with a cam he has physically modified so he can take better IR images. We're gonna try to get our 3rd digital cam in Jan, and when we do, we will turn our Sony F-717 into an infrared cam, and i cannot WAIT!!!!
