Technically, as I've noted already, the TV lights made things a bit easier than the amateur tournaments I've done up til now. These are often in very gloomy school sports halls with the ISO jammed against the upper reaches of even a D3. Here at Glow, with the TV lights, ISOs were a slightly more sensible 2500/3200, which is well within the capability of the D3S bodies I have now. Exposure was 1/640th at f4 on the 24-70, for just a little helpful depth of field. I also used my 70-200, but this lens, truth be told, is a little darker than the nominal f2.8, so I used f3.5 and the higher of the ISO settings.
White balance was also fairly simple, though I still tweaked the raw files for skin tone. A couple of quick snaps of my hand suggested the Tungsten preset, with a little extra warming (A2?) dialled in. This gave me reasonable Jpegs out of camera, though a fully-custom white balance is the way to go if shooting 'peg exclusively.
The AF setting was Continuous, with a point set which is off-centre, and used this way from previous experience. I'm not sure if this is the way the boxing "regulars' work, but it's what seems to do for me. What you do is keep the off-centre point over the boxer on that side, assuming they are broadly parallel to you, and let the camera do it's thing. 9 or 21 Point selection was active here. I might try the 3D option at the next amateur bout and see how that will work. But for now I stuck with what I was familiar with and knew did work OK.
I'm still not sure I rate Pro boxing very much. It's not a sport I seek out on TV, for example. The much longer bouts of the main events, 12 rounds, seemed to drag and just give shot after shot that looked, well, the same. Although I had over 2300 images by the end of the evening, I found I was shooting much more sparingly by the final headline fight. Amateur boxing, with its head-guards, short bouts and less "cuddling" between boxers (less blood, too...) seems much more interesting to me. It doesn't attract the big bucks, of course...
