[Wall-E]

Being a newbee and all that has been said, I need to ask a few basic questions.
When resizing is used, is it a reduction in the size of the finale print or is it reduction of the pictels. I shoot in raw and jpeg because I don't know what the end result will be. I know, in time I will understand, however, in the very beginning, I am confused with the terminology.

Print size is not 'directly' related to the number of pixels (not pictels).

Most printers have ratings of 200-300 DPI (dots per inch).
So, for a 640x480 PIXEL image, a good quality print can be had up to about 3.5" x 2.4".
You COULD print bigger, but the print quality would go down.

Resizing that image to, say, 320x240, would make it so GOOD prints would only be 1.6" x 1.2".

Remember that the image size (in pixels) divided by the DPI of the printer only gives you the MAXIMUM size for a maximum resolution print. You can print smaller than that with no problems.
