Notes:
When taking a picture with Tiff option or Email option, the camera takes a picture
at whatever resolution the camera is already set to, and additionally takes
either the 5megapixel tiff, or the small jpeg suitable for email use. Test of Sony DSC-F707 5 Megapixel Digital Camera by Brian B. Burton

More thoughts:
According to my friend, who is a printer, you need 266ppi (pixels per inch)
to do 133lpi (lines per inch) professional printing.
At 3 megapixels, you could print out at about 7.7" x 5.8".
At 5 megapixels, you can print your photo at 9.6" x 7.2".
From personal experience with an Epson 2880dpi inkjet printer, you can take
a 3 megapixel picture and print it out at 8"x10" (on photo grade paper)
and most people will not be able to tell it isn't a normal photograph. 5 megapixels
is better (and maybe to the most discerning eye sharper) but the big advantage
is that you can crop out the bad parts of a picture and still be left with enough
pixels to print out a photographic quality picture.
