Most DSLR cameras have an infra-red filter applied over the sensor. This is to shield the sensor from recording infra-red light which is normally invisible to human eyes.



Screw-in IR filters allow infra-red light through, along with some visible red wavelength. Bearing in mind that the camera has a filter to prevent it recording IR light...and there's your problem.



The long and expensive way to get round this is to have the camera adapted to mainly record IR light...but this makes it slightly useless for normal photography. There are also firms that can convert the camera to take normal pictures OR infra-red pictures...this involves removing the filter over the sensor and using the screw-in filter.



Some digital SLR cameras record infra-red light quite well anyway, for example the Pentax ist-d model.



About the closest to true IR photography you can get without adapting the camera at all in my opinion would be to use the screw-in filter on a bright sunny day, having the camera on 'b' setting (bulb exposure), setting up the shot you want with a tripod and have an extremely long exposure. This would get as much light in as possibly thought the IR filter, then on the computer you can remove the red from the image. It's not the same as true IR photography, but it's about as close as you can get without modifyingg the camera.

How much money didi you spend on your camera? How much are you going to save buying an aftermarket battery? The battery is the one part where saving a few bucks is not really worth it. The fisheye adapters work, but are usually not very good optically. It's cheap enough that it's not a big loss if you don't like it.

Answer 5

To get the black and white effects you often see you want to convert the image to greyscale in your editing program. It may be better to do this by channel controling the B&W conversion yourself rather than using the built in algorythms. Play with and see which looks best

Remember you need long exposures and a tripod even in broad daylight.
