K
Kelvin Kelvin is a unit of measurement used to quantify color temperature, which refers to the hue of light emitted by a light source. In photography, color temperature is measured on the Kelvin scale, with higher values representing cooler (bluer) light and lower values representing warmer (redder) light. The Kelvin scale is based on the theoretical color of light emitted by a black body radiator at different temperatures. For example, daylight typically has a color temperature around 5500-6500 Kelvin, resulting in neutral or slightly blue-toned light.
Indoor tungsten lighting, on the other hand, has a lower color temperature of around 2700-3200 Kelvin, resulting in warmer, yellow-orange light. Understanding color temperature and Kelvin values is important for photographers as it allows them to adjust white balance settings on their cameras to accurately reproduce the true colors of a scene under different lighting conditions. |
Keywording Keywording is the process of assigning descriptive keywords or tags to digital images to facilitate organization, search, and retrieval of images in digital asset management systems, image libraries, and online galleries. Keywords are descriptive terms or phrases that describe the content, subject matter, location, or concepts depicted in an image. They help photographers and image users quickly find and identify relevant images based on specific criteria or search queries.
Keywording is a crucial aspect of digital asset management and metadata management workflows, allowing photographers to efficiently organize and categorize large collections of images for easy access and retrieval. Effective keywording involves selecting relevant and specific keywords that accurately describe the content and context of each image, using standardized vocabularies and controlled vocabularies whenever possible to ensure consistency and improve searchability across image databases and platforms. |
