using Olympus C-700 camera. The amount of infrared light you would need would be pretty intense, as most all digital cameras now (unless specifically noted for that camera) come with filters right on the sensors that filter out infrared. The reason being that all digital sensors are innately sensative to IR, and without the filter every picture would have a reddish tint and exposures would be off.
There are certain cameras that are better at still seeing IR than others, even through their filters. For example, I have a Canon Powershot G6, and it can actually see IR alright. But in order to do an exposure with just infrared light, I would need an IR filter to filter out everything except IR, and I would probably need a long exposure, even in daylight. An IR shot at night would be a headache, as there really isn't much light of any kind around, IR or otherwise. You'd need some sort of IR light source.
You can test your digital camera to see how well it can see infrared pretty easily. Just use your TV remote. Point it at your camera and watch your display while you're pushing buttons on your remote. Most remotes use IR, and you'll see the little bulb light up on the front of the remote in your display if it can see IR.
I've posted a couple websites below that can hopefully help you. Not very successfully. The sensor is not sensitive to infrared light.
If you are really interested in doing this, Fuji just came out with a version of their FinePix S3 Pro UVIR that does not filter out the UV and IR so it will work in both lighting conditions. The body is somewhere near $2,000 and it takes Nikon lenses. like the last person said - almost all digital cameras have a special filter to block infrared light. the only way you should be able to do what you're talking about is to get that filter removed; there are actually places that will do that for you. check out www.lifepixel.com
i would talk to them first - they can probably help you make sure it will work before you fork over the cash. |
