Scanning Resolution for Book Use or Canvas Poster Use?

External Since: Apr 25, 2006 Posts: 9

I have a load of mostly 10" x 8" B&W photos I want to scan. I may want to
include them in a proper published book at a later stage, or maybe even blow
then up to poster size, perhaps even on canvas.

Bearing this in mind, how many DPI should I scan at? I believe 300dpi is OK
for magazines, books etc, but if I want the option to blow them up poster
size what should I use?

And if they're B&W, am I best scanning them in grayscale or B&W?

Thanks,

Fred.

Hmmm..You say photos, so is this film or digital? This being a digital
group, I had to ask. If you possibly have the negatives, that would
be a better option for scanning.

Yes to 300 dpi. that is what is used for printing. Your scanner
should create .tiff files which are good for prints. Make sure and
run the photos through photoshop to check levels,contrast,etc. before
printing... I would scan them in B and w. as opposed to grayscale. As
for blowing them up poster size, I use a photshop plug in from Alien
Skin called Blow UP.

I hope that helps...
