Now this an awesome school project Students Help Crash NASA Satellite Into Ocean

And the new nVidia cards are out now link

My English isn't perfect either

I hope that Pentax has some news about a TC on Photokina, I saw one the 1.4x TC SDM the last time their.

Never had that problem Don because I've build my own system and so am not at the mercy of the manufacture of the PC to provide the correct firmware.
I've successfully without problems upgraded RAM, the CPU, GPU, Harddsik, and put in a blu-ray burner separately over time.

The only problem I had with upgrading the RAM or the CPU was that I've overclocked them and they are connected to each other so if you change one you need to adapt the other for max preformance but that's only when you've it overclocked.
For the rest, if you the software or the hardware is not older than 3 to 4 years all should work without a problem.

If you want to upgrade a 6 year old PC to windows 7 that can be problematic indeed with some hardware.

No you're right photoshop doesn't need a fast card but more and more programs are capable to use the graphics card to make calculation and with the laptops I've looked at the graphics card was the lowest scoring hardware component so in time it might be useful to upgrade that together with the RAM and maybe a SSD drive.
Also the windows laptop use Ati cards and nVidia now has cards that can completely shutdown automatically when you don't need the card so you extend battery life quite a bit when surfing the web or writing a letter.

Same here with the PC around the two years, too bad the sockets in my current PC aren't used any more or else I would have upgraded it again because everything runs still fine but it's getting slow now.
Software gets update when the new one comes out since the price hardly drops for the upgrade version.

Metering mode is like the word say the mode in which the camera meters.
I believe there is in the menu the option to change that.

Pentax use 3 metering modes.
- spot metering
- centre-weighted
- Matrix

With spot metering the camera meters a very small spot on the photo and because that spot is small the exposure can change relative mugh when you move the camera a little bit. Something like this.


centre-weighted use almost the whole photo where it looks at the centre for the most accurate exposure and the "priority" get less the further it gets from the centre. It looks something like this



Matrix mode is a special variation.
The camera has several exposure meters across the screen and matrix tries to select the most important ones and try to get the best exposure based on that.
I believe it looks where the focus is locked on, if the focus is locked on the left than the matrix mode will give that part of the photo the most priority to get the exposure right.

Thank you layingback, Shaky already talked about that and that might indeed be an idea if must from the school use Mac but that isn't the case but still it might be better.

A different question, the graphics card with laptops are they baked in into the motherboard, I believe that isn't always the case so if not can you than upgrade them?
I know you can upgrade the hard-drive, optical drive and the RAM with little problem but I've no idea about the CPU and the GPU.

Indeed but I liked the series though.

The DFA from one member here took a tumble for the top of the stairs all the way down and it still worked.
Don't know who it was though who was that lucky.

No problem, I only said that the AF 1.7x TC from Pentax is the only one that makes from a SDM a screw-driving AF focus because it intercepts the digital information off the lens.
