I can't get there at the moment, but the keywords on candlepowerforums.com were "LED camera flash"; then there's this article http://www.ledsmagazine.com/features/2/4/1/1 covering some of the material. It's quite interesting. The bottom line was that the speedlites of this world put out around a million cd in a short space of time over a limited area.

... in German it's a "klammeraffe" - clip ape - but normally, these days, you can get away with "ät"

Regarding email addresses: read, maybe, the SMTP protocol - it's strongly space-based with information being delineated by a space in many cases. It makes a *lot* of sense not to have spaces there. This article from MS explains some more about how to test SMTP servers: http://support.microsoft.com/kb/153119
Try also using Robocopy with something with spaces in - it won't work. It supports the long paths in the filenames, but refuses to accept them on the command line. Spaces are a pain.

Slash is the international word. I don't know anyone outside the UK who uses "oblique". I write for an international audience - it's never an oblique.
Forwardslash as opposed to backslash - no, only Windows users tend to need the distinction, as on *nix the backslash is for escaping characters.

... there are some numbers around relating to just how much light a flash puts out in terms of candelas and therefore lumens. It's an *awful lot*. I calculated I'd need 200 XP-Gs running at well over 4A each (work out the power requirement!) for 1/100s to get close to a GN63 flash.

There are several nice links out there, including one from Kodak talking about foot-candles and their relationshop to aperture sizes and another one from a guy who measured the output of an EF500 in terms of speed of output at different settings (1/2, 1/4 etc). I can't find the links right now, which is annoying, but I'll go have a look later when I have the urge.

Bottom line? normal LEDs aren't much use except for really, really close work and even then, the colours aren't the best.

I got a mail today (I'm off for a week) with an invitation to "some cake", with no reasons given.... just a time. So I'll go and ask what's going on when I get back into the office

mine has a 5MP samsung but prefers the K10. I haven't given her the K5 to play with yet, she was shocked enough at the K10's burst mode

I have the Lowepro Voyager C on the K10D and the '5 needs one. They're much more comfortable than the original - far wider and padded well.

it's a "sawhorse"-style holder for the poles as jumps. It's also buried under two feet of snow so there's no real way to get rid of it....

and another example of "if it's not shown, it's not happening". Turn you brain off, you don't have to watch what's going on - they're not slowing down, or the lights would be showing... stupid, stupid.
And it doesn't work on ice, either.

... which is another reason you have to pass a skidpan test here before you're allowed out. OTOH, I'd like to send most Finnish drivers to Germany for a course in anticipation and serious traffic as here they have *no clue* - and the brits aren't much better, either.
