K-7 and reduced pixels

Probably for the k20d as well, but for pics that I won't be printing larger than 8x10, what happens quality wise when I drop the pixel size down for raw? In theory nothing should happen (presumably if I leave the quality setting high), but how does the camera drop the recorded setting down? Do fewer pixels on the sensor get used or does in camera firmware drop it down?

I'm chewing through disk space like there is no tomorrow and I'd like to drop the size down for quite a few of my shots...but wasn't sure if there was a drop in quality due to the technology used to make the change.

Thanks!

You can't shrink the size of the RAW file - its always captured as a 14MP file on the K-7.
Which gives you a clue to one question - all pixels on the sensor get used.

When you record JPEG at lower megapixels, the camera reduces the amount of information recorded by averaging information from adjacent pixels.

So you always lose detail when you reduce the MPs recorded, but it is immaterial if you match it to the size of the print you will be making.
..e.g. 6MP prints very well on A4 paper, or viewed fullscreen on an average PC monitor.

Thanks Kittykat46......I've set my camera to raw since the k10d and haven't thought of shooting jpeg.....I forgot that raw is just..well raw. The K-7 seems to mainly have fixed the white balance and other issues....but every once in a while it's nice to rescue a screwed up shot which means it needs to be in raw....

I'll buy another set of disks...lol

External HD's are very reasonable these days and value-wise versus the quality of your photos, is a no-brainer.

Check this one out, 500gig HD for under $90...should take quite some time to fill that one up!

Thanks Jasvox. I have a RAID setup for storage....I just don't trust it so I always want two copies. Just are transferring my laptop photos to a bigger drive..
