What Does Image Quality Mean When Talking About Photography?
When talking about photography the term ‘image quality’ also referred to as ‘IQ’ is characteristic of an image that measures the perceived image degradation (typically, compared to an ideal or perfect image). Factors that affect quality include brightness and evenness of illumination, contrast, resolution, geometry, color fidelity and color discrimination of an observed image. Achieving the highest possible image quality relies not only on using the best available equipment, but also making correct photographic choices. Correct use of exposure, lighting techniques, and post processing techniques all effect the overall quality of an image.
