Print Specifications

Hey all. I was wondering what resolution you print at for poster size? I have a nikon coolpix 885... it is 3.2 megapixels, so it takes 2048x1536 pics at 72 dpi... which comes out to be like... 28 inches x 21, or so. Would that come out ok, if i printed it at 28x21 at 72 dpi? Or is it necessary to print things at 300 dpi, reducing the image to roughly 6x5? Ok, well thanks in advance.

You pretty much answered your own question. There are numerous sites and tips about resampling vs resizing etc, but as you thought, in the main you will need to print near 300.

Some images may get away with a lower res, but rule of thumb is go for 310 or thereabouts.
