Photoshop Chapter 7

The standard resolution for on-screen graphics is 150 ppi.

Images that are going to be professionally printed should have a resolution of 300 ppi

A bitmap image is basically a grid of thousands of pixels.

To change the resolution of an image in the Image Size dialog box, the Resample check box must be checked.

In the Image Size dialog box, if the Resample check box is not checked, you cannot add or remove pixels, even if you change the resolution.

Cropping an image can help the viewer focus on what's important in the image.

The Crop tool has a built-in straighten option found on the Options panel.

Photoshop actions are recorded on the Animation panel.

An action can be stopped at a specific step to open a dialog box.

Snapshots are another name given to actions on the Actions panel.
