The 2848 x 2136 setting (6 megapixels)
is a good setting for 8 x 10 prints.
For 14 x 17 I would use the same 6 megapixel setting.
The 4048 x 3040 setting is a six megapixel shot that is interpolated into 12 megapixels.
This is the same as using software to increase the size of a photo.
It results in degrading the quality of the photo.
Using the 12 megapixel interpolated setting to print a 8 x 10 photo would not be a good idea.
I don't know of any good use for the 12 megapixel interpolated setting for any reason.
I know you can't convert sparsely recorded pixels into a fabulous photo, and that you should select the highest quality camera mode for your particular purpose when you take the photo.
My object is family and nature closeups I'd like to reproduce as cleanly as possible and save forever. My camera (Fuji FinePix E550) has 6 quality options. I'm using the setting recommended for printing up to an 8X10 = 2848X2136 pixels. Is that OK for my purposes?
I've hesitated going to a higher pixel count because there's a caveat in the manual that says there's a greater chance of speckling with the higher settings. But would a higher quality setting be worth chancing that problem to enhance an 8X10 further, or just be overkill? Higher setting options are 4048X3040 - normal and fine - for printing up to a 14x17 size, which I don't find the need for now.
Thank you again. (The answer to my last question solved downloading.) zippykp
