Billedteknik

Billedteknik refers to the methods and processes used to create, capture, process, and reproduce images across media. The term encompasses both the technical and artistic aspects of still photography, film, and digital imaging, as well as related disciplines such as graphic design and medical imaging. It covers decisions made at capture, during processing, and at output to print or display.

Capture and optics: The capture phase relies on lenses, sensors, and lighting to determine image quality and mood. Choices of shutter speed, aperture, ISO, focal length, and illumination influence sharpness, depth of field, motion portrayal, and dynamic range.

Processing and post-production: Digital workflows involve converting sensor data, often in RAW format, into final images. This includes color correction, white balance, tonal adjustments, noise reduction, sharpening, and, when needed, retouching or compositing. Aesthetic goals and technical constraints guide edits.

Color management and output: Accurate reproduction requires color management, calibration of cameras and displays, and appropriate output profiles for print or screen. Decisions about resolution, file formats, bit depth, and media characteristics affect final appearance and longevity.

Archiving and metadata: Images are organized with metadata, including rights information and creator credits, to support reuse and long-term preservation. Standardized formats and backup strategies help ensure accessibility over time.

Applications and evolution: Billedteknik is central in journalism, advertising, portraiture, landscape photography, cinematography, broadcast graphics, and scientific imaging. The field continues to evolve with digital sensors, computational photography, and AI-assisted workflows.
