I was just wondering, if I wanted to use a cap-style reflector setup, could I just mount 3 SFH485P on my monitor/TV to produce the IR to reflect back to my camera (PS3 Eye) or would I need a different kind of LED for that?

If it's for indirect IR-light you can use any other IR-LEDs you can find.
Look for the ones with high radiant intensity.

Or this kind of IR-spot:

In my opinion just three LEDs will not be enough for it.
You have to find good reflection material also.
Try and give us news.

Sorry, I don't know the right term in English.  :gene:
Kind of reflective tape you can found on safety vests.

I use this one on kites for night-flying and it's works very good. IMO it must be working for a reflective head-mount also.

Thanks for the tips. I'll look at getting something bigger/more powerful like that IR-spot then.

Bought the one from conrad.

Might be the filter, I'm using a floppydisk. I still have to try overexposed film.

If you have one of this 3d glasses with red and green plastic films (they often comes with 3d films in a DVD box) you can put the red above green in front of the webcam. This is a very effective filter. If its not enough put a third layer of green or red.
