Any of the Sony 1-CCD camcorders can be modified to prevent the
IR switch from also forcing the camera to widest aperture and too
slow a shutter speed for daylight IR video (first installed in late TRV9s
due to Sony's silly prudery and the myth of "x-ray" vision for the
camera - but fortunately, mine is an earlier version, and not hobbled
by this nonsense). One day I tried it outdoors, and it worked fairly
well, so I added a red filter, and it worked better yet. A polarizer
improved the results further, and finally replacing the red with an IR
filter worked very well. I use the camera in B&W mode to lose the
"tooth paste green" look...;-) BTW, I prefer IR in motion to stills
(it is just plain more fun - and somehow less "hokey" looking...).
