Quality refers to the production standard of an image. When assessing the image quality of a print, the following elements may be considered:
- Image content
The content is an essential element in quality. A minimally acceptable image should be in focus and properly exposed. A high quality image would be well composed, original or innovative, and have a story to tell.
Color is a factor both in the content of the image (is there a color theme that fits with the content of the image) but also in the final presentation of the digital or print image (is the color reproduced faithfully to the artist's intent).
How long will the image last in it's current format? A cheap print, for example, may discolor after a few months where as a higher quality print is expected to last 100 years before significant degradation is observed. Some print formats, such as printing on metal, may even extend print life up to an estimated 200 years. The longevity of digital images is dependent on the way in which the image is stored - CDs, for example, may degrade after 10 years - and how quickly technology changes and evolves.
