Make Images Have a Higher Resolution on Photoshop CS4
It may seem bizarre that an image can look one way on the playback on your camera, another way on the computer screen and yet a third way printed on paper, but all of those views are linked to something called pixels, which can affect resolution. Resolution relates to how an image looks printed; the higher the resolution, the more realistic and crisp the picture looks. On the other hand, lower resolution can cause blur and fuzz. Avoid low resolution pitfalls by increasing your image's resolution using Adobe Photoshop. With a few clicks in Photoshop CS4, you're able to tailor resolution, increasing it as required.
Instructions
1. Open Photoshop CS4, click the "File" menu and select "Open." Navigate to the image to increase resolution and double-click the file name. The picture opens in the Photoshop workspace.
2. Click the "Image" menu at the top of the screen. Select "Image Size" to open the "Image Size" window.
3. Type a new number into the "Resolution" box halfway down the window. Note that the numbers in the "Pixel Dimensions" boxes at the top of the screen change as the resolution changes. Click the "OK" button and the image in the workspace adjusts.
