The solution is simple: with all my Sony camcorders, I
get the best daylight white balance with the DWB preset
selected (and then it is quite good...). IR has nothing
to do with it, and "hot" objects will not expose the
tape due to temperature. It is possible to shoot IR with
these camcorders, though, with "night shot" and with
enough ND filtration + a red or no. 87 IR filter added
(see: www.David-Ruether-Photography.com/ir.htm for samples shot
with the daylight-IR enabled older TRV9 camcorder).
BTW, if the color is still too blue for you with DWB
selected, add a "skylight" filter (it is slightly
salmon-colored, and can be had in various strengths).
(Some people prefer red bias in their video images, a
mystery to me... - but, many TVs are blue-biased,
perhaps explaining this...;-)
