Glossary Of Photography Terms [1]

Image Resolution Image resolution refers to the level of detail and clarity present in a digital image, typically measured in pixels per inch (PPI) or pixels per centimeter (PPC). It represents the number of pixels or discrete units of color contained within the image dimensions, both horizontally and vertically. Higher resolutions contain more pixels, resulting in finer detail, sharper edges, and smoother gradients. Image resolution influences the quality of prints, displays, and reproductions, as well as the file size and storage requirements of digital images.

Resolution requirements vary depending on the intended use of the image, with higher resolutions generally preferred for professional printing, large-format displays, and high-quality reproductions, while lower resolutions may suffice for web publishing, social media, and digital viewing. Resizing and resampling techniques can be used to adjust image resolution while maintaining image quality and aspect ratio according to specific output requirements and viewing contexts.
