Daniel is very much preoccupied with his new offspring at the moment, and also some other committments, so hasn't been able to participate recently. He is still a member of the team, perhaps on sabattical would be a way to describe the position.

He'll be back and also can always be drafted in if needed.

Thanks for asking.

It depends whether or not you need to adjust WB at all. For very precise applications maybe. For example, in advertising a Cadbury's wrapper has a very precise colour and this needs to be the same, everywhere, all the time.

For more pictorial uses I generally just use Daylight. I turn off the camera fine tune so it is a fixed value and the colour is superb. One of the Pentax strengths is the fine colour reproduction.

If you use RAW then you should be able to also choose daylight setting or, if you want a warmer result choose Cloudy.

It depends on where the point of focus was chosen. We don't know if it was centre point, somewhere else, or whatever. It's entirely possible the camera selected an inappropriate point.

back on topic please folks.

Thanks Gwyn.

Don't forget they will be very nervous and taking no chances. If they get it wrong and there's an incident it will be case of why weren't you more diligent, not a case of well photographers are OK.

Tensions could well be high.

Yes, it looked like a great idea.

Hopefully we're discussing anything that will be relevant to us thinking of shooting pictures at the Olympic Games.

Personally I won't be as it seems far too much hassle, plus my interest in sport is very limited.

Those who will be shooting images need to be aware of any likely pitfalls, so they can avoid them.

I'm not sure if there's an IR setting in the menus, but the usual method is to process in black and white in Photoshop. I would try out the black and white setting on the K-r, which might help.

If you want colour IR red images (false colour) then I'm not sure. I'd have to experiment if I wanted that effect and would probably look first to Photoshop.

That answers one question. I presume you shoot in RAW. As I shoot in JPEG I can rattle off rather longer bursts than that.
