Setting General Preferences

Photoshop's General preferences help you configure some of the more common features of the program. Image quality settings, as well as the new History log are setup in General preferences. Other options such as showing Tool Tips, beeping when an operation is finished, and using Smart Quotes, can all be turned on or off in the options area. The new History Log lets you save all the History States performed on a particular document. For example, when you open an image, all the adjustments and actions performed can now be saved in a document file. This gives you access to valuable information, and lets you reproduce the steps performed on one image, to correct the contents of another.

    History States impact Photoshop's performance by holding the History States in RAM memory. The more History States used, the more RAM memory is required. Using an extensive number of History States can impact Photoshop's performance.

Working with Image Interpolation

When you change the resolution of an image, Photoshop adds or subtracts pixels to comply with the new settings. For example, when you change the resolution of an image from 72 PPI (Pixels Per Linear Inch) to 144 PPI, Photoshop must add more pixels. Conversely, if you reduce the resolution, Photoshop must remove pixels. The image interpolation method determines how Photoshop completes this process. You can use the Nearest Neighbor method for the fastest way, but it produces the poorest visual image. Or, you can use the Bicubic Sharper method which takes the longest to perform, but produces the best visual results.
