I have gotten a ''bad'' camera and had to manually remove my IR filter by hand with a needle. Before, there was no differance beetwen normal and IR LEDS, now it works like a charm. Is IR filter removing a must? no. Is it ideal? YES. Bye good PS3, you mean the old one? In old PS3 eye, the just had to unscrew the lens and you could remove the filter. as simple as that. if you took an old eye (wich is ''the good one'' for me) than just look up a tutorial on how to do that, if you really can't find any, say it and i'll send you one, i've seen some. Now, if you meant something else by ''good one'', you will have to remove the filter by other means like me. It isn't hard, its long and require precision, like de-liding, you just don't waste hundreads of $$. You will spot the IR filter easilly, it is a blue piece of glass that has red reflection, you can't miss it. If you have more question, ask and i'll answer, i've made A LOT of reschearch before modding my cam, so i might have answers.
