Step 1: Materials & Tools
Step 2: Check Your Camera
So how do you know if your camera has an IR blocking filter? Turn the camera on, get a remote control of some kind (TV, DVR, etc...), point the front end of the remote with the IR LEDs in it towards the camera lens and press any button. You should see them light up if your camera is sensitive to IR light (they'll look purplish). Congrats!
If you don't see anything, make sure the remote isn't dead. If you still don't see anything, then you have a good camera and unfortunately the only way to continue is to take it apart, which is outside the scope of this project.
