What factors can affect how an image is perceived on a screen versus in print?

1. Image resolution alone

2. Color representation techniques used

3. Light exposure time

4. Object distance from the lens

The correct answer is: Color representation techniques used

The correct choice focuses on color representation techniques as a crucial factor influencing how an image is perceived on a screen compared to print. Screens use additive color mixing, meaning colors are created through the combination of red, green, and blue (RGB) light. In contrast, printed images employ subtractive color mixing, primarily using cyan, magenta, yellow, and black (CMYK) inks to create a full spectrum of colors. The differences in color models can lead to variations in how vivid or accurate colors appear in digital versus print formats. When images are rendered on screens, the light emitted by the display can result in more vibrant colors and a different perception of contrast, which may not be replicated in physical prints. On the other hand, print color may appear softer or more muted due to the absorption of light by the inks and paper. This essential distinction in color representation techniques directly affects how audiences perceive an image based on its medium. While factors like image resolution can contribute to quality, the way colors are represented is a more significant aspect when comparing visual experiences across different mediums. Light exposure time and object distance from the lens also play roles in photography and imaging but are less relevant to the comparison between screen and print representations.
