Handy for people who don't know how to use good interpolation programs, to determine results before printing. But in reality a properly calibrated printer will not make a good image bad, or a bad image good.Having initially suggesting the SD9 has not a lot to offer, I have
read lots of other postings and come up with the theory we must
rate the image in 3 common ways.
1. Printing on inkjet, just to full numberr of pixel staight
through your printer driver
When viewing at 100% you crop the image to your screen size so a 2MP image will essentially have the same same quality as a 11MP image crop, There is just more of it.2. Viewing 100% on our VDU, and there are at least 3 kind out there!
This is where X3 shines and is responsible for the wow factor. It has more detail per pixel, so it looks better. Doesn't mean it contains more detail just that you see more of it at once, so it looks impressive.
A lot of detail thrown out, so this is primarily a quality judgement about color and composition, not the camera that took it. When you see people asking for more pixels, they want to see the cameras capabilities and not the photographers.3. After sizing to 800 or 1024 pixels wide and viewing at 100%
