Scream of the Crop how to resize and crop photos - The Adobe Photoshop CS6 - page 139

So, since you saw earlier how much resolution you need to have to create a

decent-sized print, how do photographers get those huge poster-sized prints

Resizing for
Poster-Sized Prints

without having super-high-megapixel cameras? It's easy—they upsize the images

in Photoshop, and the good news is that unless you need to resize your image

by more than 300%, you can do this all right in Photoshop without having to

buy a separate resizing plug-in (but if you need more than a 300% size increase,

that's where those plug-ins, like OnOne Software's Perfect Resize, really pay off).

Step One:
Open the photo you want to resize, then
go under the Image menu and choose
Image Size . When the Image Size dialog
appears, in the Pixel Dimensions section
at the top, to the right of the Width field,
you'll see a pop-up menu where Pixels
is chosen (if this section isn't active, turn
on the Resample Image checkbox at the
bottom). Click on that menu and choose
Percent (as shown here). Both the Width
and Height will change to Percent, be-
cause they're linked together by default.

Step Two:
Now, type in either 200% or 300%
(although there is some debate about
this, it seems to work best if you move
up/down in 100% increments) in the
Width field (again, since they're linked,
the Height field will automatically change
to the same number).
