| Percentage | Unit of Measurement; Commonly used in CMYK, used to determine color values based on 0-100 |
| Resolution | Resolution Choice; A measure of the amount of detail that is stored in a digital image. |
| PPI | Resolution Choice; Pixels per Inch. |
| On-Screen Resolution | Resolution Choice; The resolution that is by default on the monitor. |
| Print Resolution | Resolution Choice; The resolution at which printers can print measured by DPI |
| DPI | Resolution Choice; Dots per Inch. |
| RGB | Color Mode; Commonly used digitally, assigns an intensity value ranging from 0 to 255 for each red, green, and blue values. |

| Filters | Used to apply special effects to an image that would be too difficult to create manually. |
| Clone Stamp | Samples an area of an image and then allows you to paint over another area of the image with the sampled area. |
| Blend Modes | Change the way layers interact by determining how a layer will blend with the layers below it. |
