Resolution

Resolution refers to the amount of detail an image holds and is typically measured in pixels per inch (PPI) for digital images or dots per inch (DPI) for printed materials. Higher resolution means more pixels or dots are used to create the image, resulting in greater clarity and sharpness.

Key Points:

• Digital Resolution (PPI): Determines how many pixels are displayed per inch on a screen. Common values include 72 PPI (web) and 300 PPI (print).
• Print Resolution (DPI): Refers to the number of ink dots a printer can place within an inch. Higher DPI means finer print quality.
• Image Dimensions: Resolution works in tandem with image dimensions (width × height in pixels) to determine the overall quality and size of the image.

Example:

An image that is 3000 × 2400 pixels at 300 PPI will print at 10 × 8 inches with high quality.

In summary, resolution is a critical factor in both digital and print design, directly affecting the visual quality and output size of an image.
