Once had the intention off putting them all down on paper, I think I got most of them link

ED Glass - extra-low dispersion glass – Reduce the amount that light disperse when leaving the glass thereby reducing chromatic aberrations.

AL - Aspherical Lenses - a lens whose surfaces profile is neither a proportion of a sphere nor of a circular cylinder, is used to decrease various optical aberrations

I'm more worried about the internet connection, what are you're upload speeds???
I doubt you can stream real time HD with a normal connection.

Can you tell me around what time off the video since I've no idea what you mean with noise or what kind of noise.
I went through the first 3 points.

I think you mean the light grey part or not?
But this all about white balance and not exposure.

It's true more information is captured at the right/brigth end of the spectrum so you actually need to use a darker card because the camera will over expose that to make it grey.

But not anymore with the K7 since that one compress the DNG files, I believe they are now roughly as big. The K10D, K200D, K20D ect. didn't compress the file and that's why they are so large.
I've no idea what the K-X does.
Just found it, the K-X compress them as well.

Found some filesizes on the US forum for the K7.
PEF: 12.1 MB (12,669,434 bytes)
DNG: 12.2 MB (12,743,732 bytes)

Difference: 74 KB (74298 bytes)

If you're using Adobe software DNG is the easiest way to get compatibility, other converters/software might not like DNG though.

Well no because the card is darker your camera overexpose relative to the 18% grey card. And since 12/13% seems to be what the camera meters you get the right exposure actually

The question is are those cards presented as 18% grey for photography exposure truly 18% grey are do they simply use the name since everyone thinks you need 18% grey?

The 3.2 Beta is out but not the final version

Indeed when shooting I only think about the photo but at home processing the photos things sometimes gets complicated

About the grey card, I wonder if there aren't two versions around there.
One according the ANSI standard so 12% and the other neutral grey so 18%
Would need to check out various card at the shop I think ^^

Indeed like book or film titles, it's a bit off a teaser.

Or simply shoot in DNG.
DNG isn't bounded on camera models like how PEF off the k10D are differnt then from the K20D. All DNG are sort off equal so no need for updates.

That's the thing, I don't know how keen Samsung is on giving cash back offer since you didn't had a contract with them but I don't know the UK law.
