shooting at 1600 X 1200 =1920000
File Size = 1920000 X 3 =5.76MB
Image dimension = (1600 / 72) X (1200 /72) = 22.22 Length X 16.6 Breath
If u wanna print e pic wif a printer having 200 DPI output-resolution, change yr image of 72 DPI to 200 without re-sampling e image n e picture dimension will change to:
(1600 / 200) X (1200 / 200) = 8" X 6"
Of cos U can print a larger pic by re-sampling or interpolation but in throry, it will degrade e pic.
wif gd re-sampling software, e degradtion is negligible but work within the range of 6 to 6 times e original pix dimension. Thus. u could hv a print size up to 18" X 24" taken by a high end consumer camera n a print size as big as 36" X48" taken by a professional high end camera

At the risk of sounding like a show-off....
Go down to Kim Tian Color Centre and see the cat prints they put up lor. Those are 2mp shots (up to 10R).

Ask for Kelvyn or Alfred
Ask to see Azure's prints. Easy way to settle, no?

With all the camera manufacturer's marketing flak, now every other person think that you need a 6mp++ camera to do 8x10/A4 and that 2-3mp cameras are useless at achieving that. ;p
I still remember in the good old days, the marketing flak of 2mp cameras say "Print up to 8x10"
The proof is always in the final print. A well captured and processed 2mp shot can indeed be printed to at least 8x12" (I've been there done that). I've also successfully printed 10x15" from a 3mp camera.

Yup, CK, that's why I loved my late 950 so much.
Of course, basics of a well-taken pix will have to be there lah. If one gets a 6Mp cam and takes a bad shaky shot, even 3R size may not hide it.... Then again, a good 2Mp shot can suffice even for offset printing. Have seen some of my clients use 2-3Mp shots and they turn out better than re-scanned 4Rs in their annual mag.
