Scanning for big file

Say you want to scan an image for a print size of 11x14. Would you set the res for 300dpi and put the image size in the box or pixels and how big would you want to scan at ?:confused:

first of all i really can't understand what you wants to ask?

ok
what we normaly do is..........

if i have a small image and i wants to use that image for the
printing of poster of a big size.........

in this case we scan that image whith having option for the sacning is

100% image size and we normaly givies the DPI 600 or 300 (depends image qulity).........

because of that when you open that image into the photoshop and increase the image size at that time the image will remain same as like before incresing the image size.............

just follow this procedure this will help you ....
