Where do I find DPI?
Photoshop is a great software program to quickly look up the DPI on any image. 1) Open your image up within Photoshop 2) Click on Image and then Image Size 3) A small box will pop up on the screen and show you what the Resolution is.
How can I change the DPI?
In the box that popped up within Photoshop, you can change the DPI next to the text that says 'Resolution'.
