Camera policy in Lynah?

Andy, though not up to Age's standard those aren't bad at all! Thanks for sharing!

What's wrong with taking the photographs as RAW and figuring out white balance post shot manually?

I always shoot RAW, but to at least get the viewfinder looking good, I set the camera WB.

For those, I took a WB sample using ufraw's dropper tool off of the ice.  Unfortunately I can only do single-pixel dropper or full-image automatic.  I need to request "area" WB sampling as a feature or ufraw.  :)

For the second game, taking a camera WB sample off of rough ice at the beginning of the game seems to have given good enough results even moving the shutter speed up to 1/250.  I COULD tweak things a bit more per shot, but using the same WB for everything gave acceptable results.

Friday was my first attempt at hockey photography - I have a LOT of practice (and experimentation) to do, and also really need a 70-200/2.8 lens.

Two tricks that helped a lot:
1)  With the exception of the edges of the rink, illumination was reasonably constant.  I set the camera to manual exposure at the smallest aperture used by my lens to avoid having to compensate for it being variable aperture.  Unfortunately this meant sitting at f/6.3
2)  Aforementioned WB settings

I keep forgetting to start the upload of Saturday's pictures before leaving the apartment.  :(

Forget whites, what's up with the crimson jerseys on the cornellbigred web page about NCAA tickets? Say nothing of it being last years Grand Rapids picture, maybe the color faded.B-]

http://andydodd.smugmug.com/Cornell/Hockey/ECAC-Quarterfinals-vs-Harvard2/11596081_JnqxC#817194360_3WUdu - Saturday 3/13 game.

Sharper shots in general, but I think I caught some better "moments" the night before.  As you can see, the WB is starting to vary a little at 1/250.  Worst is one of the pictures of the nearest leftmost corner of the rink, caught the light at a really reddish point in one picture.

You want better color balance, hope Cornell plays its next ECAC quarterfinals at Quinnipiac.

IMO color that's off in one corner of the photo or the background may be the lights cycling through the color spectrum at different times. One may be in its blue period, another in red.

Andy Dodd

Yup, exactly Bill.  (by the way, I saw your pictures from Albany, they were excellent!)

Fortunately at 1/250, while the color shifting with time starts being noticable, it's not horrible.  (unlike those 1/500 bursts above).

The question, of course, is how much worse it gets going from 1/250 to 1/500 in Lynah - Lynah's lighting may not shift as much as the lighting of the example given above.

I understand there are reasons for color problems, but hoped crimson wouldn't show up on cornellbigred.com, at least not if they were standing up. Flat on their back, crimson is a good color.

In that case, it's probably a combination of slight WB errors and slight underexposure (cameraperson might have used autoexposure, not manual tweaked so white was as bright as possible w/o getting blown out).  I'd have to check a histogram of the image to see for sure.  Underexposed red is probably going to look crimson-ish.

Of course. When you have something inferior to red, it's crimson.

Automatic white balance goes beyond admitting from Exeter and St. Marks.
