Smarter Image Upsizing (Even for Low-Res Images)
Another thing I love that Adobe's engineers do in each new version of Photoshop is that
they go back and make existing features even better. In Creative Cloud, they came up with
a new option for upsizing images (making them larger using the Image Size dialog) with
a new mathematical algorithm for upsizing your image while maintaining more detail and
sharpness than ever before (and this includes better results from upsizing a low-res 72 ppi
image).
Step One:
Here's a low-resolution 72-ppi image we want to resize to a high-enough resolution to
make a print of it. Go under the Image menu and choose
Image Size
to bring up the Image
Size dialog (by the way, the Image Size dialog is resizable). You can see our image has a

is turned on and then choose
Preserve Details (Enlargement)
from the Resample pop-up
menu. When you do this, a Reduce Noise slider appears beneath the menu that might come
