Raising/Lowering Pixel Density

Are there any easy ways to do this, I don’t feel like going through photoshop’s 15 thousand functions to figure out how. Obviously for photoshopping something into a picture.

Uh, do you mean opacity? Masking?

No, pixel density. Aka, how many pixels are used in an area. If you take a low-pixel density image and try to cut-paste a section onto a high-density image it looks terrible. Trying to find an easy quick fix, by either raising the density of the lower image, or more realisticly, lowing the density of the higher.

Just say resolution.


Right-click the title bar of the image in PS, and change the resolution. Default is 72 pixels/inch, I believe.
