3:2 resolution setting
 
The camera I have can do 2560x1920 and there is another setting which is called 3:2 ( which = 2560x1704 ) What is the purpose/benefit of using the 3:2 setting? Is it better for prints?

Thanks!

The 3:2 setting has same aspect size as 35mm film(ie 24x36 mm) rather than the actual size of the CCD. The benefit is the stored files size end up smaller which most people end up doing anyway cropping a 2560x1920 size to fit a 5x7 or familiar with film format.

Thanks NHL,

Setting it to 3;2 (2560x1704) for all photos as I'll be doing a fair amount of prints...increased the amount of storage on my 256MB CF from 105 to 117 as well ;-)

That's what I used to do on my CP990 as well...

The 3:2 aspect ratio produces perfect 4x6" prints with no cropping necessary. In the regular 4:3 aspect ratio you always end up cropping out some of your picture when making 4x6" prints. The vast majority of prints that people make are 4x6" so ...

If you're shooting specifically for tube TV screens, or Power Point full screen, they are better suited to 4:3. BUT the world is changing with plasma/lcd's and you'll need 16:9 - which is 1.8:1!

Thanks again for the help everyone. However, I have another question...
Everyone has mentioned using the 3:2 ratio for 4x6 prints, what about other sizes such as 8x10, 11x17, 13x19, etc.?

3:2 ratio is better for all the sizes you mention above, except for 108, which is closer to the camera's normal 4:3 ratio.

is there software that does this in "bundles"? i use 4x6 prints and it's infuriating having to crop them on eby one. if i leave it to the processing company they often crop the wrong part of the shot.

Why the hell digicam's are 4:3 i will never know ... very annoying.

CCDs start life as the receptors for video camera as displayed for 'tube TV screens' as voxmagna righly described... Only lately has company like Kodak or others in the camera industries have started to catch on and make CCDs with the 'correct' aspect ratio for the cameras instead of videocams. However, what is a correct aspect ratio...

Has anyone ever heard of the upcoming 4/3 systems from Olympus and Kodak?
