I also have such adjustments, ATI Radeon here. The difference in opinion
about usability may simply be what I cionsider a dark room? I've tried using
it in a typical basement rec room (12'x20') at night with only two 60 watt
lamps illuminating the room, e.g. typical gamers illumination

It fails
where-as my cheap webcam and it's automatic brightness and contrast feature
provides a "good enough" image. I feel the Fuji would work extremely well in
a well lit room (e.g. ordinary house/apartment with daytime sun coming into
room) or pointed outside during daytime. However, my "webcamming" tends to
be in the middle of the night in said "dungeon"
As far as the overlay goes. That'll only work if/when the capture software
is using "overlay" (often called preview) mode. Not all software uses this
including, I believe, NetMeeting and the newer Messenger. Also, changing the
overlay brightness would affect both the "other" webcams/video-in capture
devices I have, DVD playback and as well avi/divx etc. and as they're just
fine as is, a brighter overlay would "wash them out".
I have three "webcams", a cheap Creative Webcam (USB), camcorder connected
to video-in on video card and the Fuji S602. By far the best image is the
Fuji, the worst is the cheap webcam. However, the most versatile and usable
is the camcorder's (turned on, no tape, no timeout) composite out connected
to the Radeon's video-in. Reason is because the zoom as well as the
automatic brightness and contrast control a camcorder typically features all
work. For example, if it's setup some distance away from subject (far corner
of room), said subject can more or less freely move around room and stay in
focus, camera will adjust for shadows and other lighting changes etc. etc.
Also I'll note, given that most webcamming is person to person video, a good
camcorder captures a more than adequate pic Give me a nice view out the
window at some mountains or some jagged ocean coastline and then I'd use the
Fuji
Only problem I have is ATI doesn't provide a VFW driver but only a WDM
driver for the Radeon hence camcorder can't be used in some software.
