Nikon D60? "I can mod my Self Help is IR light?
I want to change my AF Illuminator infrared for two reasons. 1. chamber IR can be seen, of course, 2. Assist AF light is blinding to other people in dark situations, is it possible, has anyone made you have a tutorial?
Just to add to what Caoedhen said, the approach helps external flashes have some advantages: first usually glow red instead of white, which makes * much * easier on the eyes. They work with all AF points (not only the middle one). And since the lamp is further from the saddle of his light is less likely to be blocked by a big lens. Now the real problem with a IR assist light (as opposed to red light) is that it could throw off the focus. The light in these wavelengths interact with the optical system in a slightly different farmhouse visible spectrum. That is why manual focus rings are traditionally marked with an independent indicator of infrared film. Also not all lenses perform well with infrared, regardless of how they are concentrated.
