Blue videos.

Sorry dont know anything about camcorders, but with stills u adjust the white balance depending on the lighting, and if you are sensible and shoot in raw then you can adjust the white balance at the editing stage, not sure if some digital camcorders work in this way, would only work if the scene was consistant, ie, all snow or none at all.

 

Yep it's that ol' white balance for camcorders as well as stills.
Auto usually works very well (in my experience), if you have manual WB .... even better, but take a sheet of white paper with you to hold in front of the camera while you adjust - all a to bit fiddly really.
If video looks a bit blue then they've probably got it on a WB preset for indoor setting .... I think!
Most video editors should be able to adjust the hue in post though.

 

The auto white balance on most digital cameras tends to struggle with snow and artificial light (street lights etc.). I found one of THESE quite useful at times. It folds into it's own small bag and it won't break the bank.

 

When I did stills I found that if the colour balance of a scene &/or the exposure was a bit uneven and I couldn't expect the camera to do automatically what I wanted it to do, I would change to manual and get a reading off the trackbed for both exposure and colour balance. The trackbed is around the same as a 'grey card' for exposure purposes and the colour balance is about right too.

Snow, horrible stuff! Not only is it cold and wet and slippery but it will fool a light meter like nothing else! If the trackbed is pretty well clear of the stuff then my advice given in Post 5 is still true, but if not then a reflective light reading can all too often be wrong. Try, if you have a hand held light meter, to do an ambient meter reading - one where you add the white thingy to the meter and measure the light falling onto the scene rather than the light being reflected from it. Two other choices are to try experimental shots of the scene while you're waiting for the train (they can easily be deleted off a dslr) and choose the right one. The only other technique I know of is to do what professional photographers were doing at the wedding of a friend's son which I attended about two years ago. They had an attachment to their cameras which looked for all the world like an old fashioned filter, but it was actually the equivalent of a 'grey card'. They pushed the 'grey card filter' onto the front of the lens, took a reading and then, having removed the device, took their shot. They told me it was very effective and certainly the pictures were very well exposed in what was a tricky lighting situation, ie low, but bright, November sun in the partially heavily shaded walled garden of a Winchester hotel. Might be worth trying!
