Grunnmynd

Grunnmynd is an Icelandic term that translates roughly to base image or master image. It denotes the original, unmodified image file from which other versions, edits, or derivatives are created. The concept is commonly used in photography, graphic design, digital archiving, and geographic information systems (GIS), where a central source image serves as the authoritative reference for all subsequent work.

Etymology and scope. The word combines grunn- meaning base or foundation with mynd meaning image or picture. In practice, a grunnmynd is the primary file kept for provenance and quality control, against which changes and restorations can be measured. It is typically stored in a secure, high-resolution, and well-documented form to preserve its integrity.

Usage in workflows. In creative workflows, the grunnmynd acts as the master copy. Editors produce derivative versions, such as cropped, adjusted, or compressed copies, while the grunnmynd remains unchanged. In GIS, a grunnmynd can refer to a base map or orthophoto that other spatial layers are aligned to. In digital archives and publishing, maintaining a grunnmynd supports authenticity, reproducibility, and rights management.

Rights, preservation, and metadata. Because a grunnmynd often constitutes foundational intellectual property, organizations emphasize proper rights management and version control. Metadata accompanying the grunnmynd typically includes creation date, source, equipment used, and provenance to support future access and verification.
