How to Set General Preferences in Photoshop CS6
The General Preferences pane in Photoshop CS6 is where you select some options that are, well, general in nature. You can select some choices from drop-down lists, and others are check boxes you can select or deselect to activate or disable that option. Here’s a rundown of options in the upper part of the pane:
Color Picker: Use the familiar Adobe Color Picker to select precise colors or work with the Windows or Macintosh system color pickers, as desired. You might want to use the Windows or Apple color picker, for example, if you’ve previously defined some custom colors outside Photoshop and now want to make them available for a Photoshop project.
HUD Color Picker: The HUD (heads-up display) Color Picker lets you quickly select colors within the image window without having to access the Color Picker. Choose whether you want a strip or wheel of color.
Image Interpolation: When Photoshop resizes an image, it must either create new pixels (when making the image larger) or combine existing pixels (to make the image smaller). To do this, the program examines neighboring pixels and uses the information to derive the new or replacement pixels.
You can select the type of mathematical algorithm Photoshop uses to do this, though you likely want to stick with the new default option, Bicubic Automatic. This algorithm automatically detects what algorithm will work best for what you are doing with your image.
Note that you can also now choose your desired algorithm from the Options bar when transforming your image.
