Hi all,

I have few questions here:

For a DC with 4 megapixel,

Q1.
what is the max. size of photo that it is able to print without any quality degradation?

Q2.
If I use this camera to take a photo with only 1900 x 1600 (i.e. the max. pixels of 3 megapixel DC), does the photo quality will be same as the one taken by 3 megapixel DC?

For a DC with 3 megapixel,

Q3
what is the max. size of photo that it is able to print without any quality degradation?

Thanks.

For acceptable print quality, divide pixel width/height by 150(ppi).
For best quality, divide by 300ppi.
