Derivative Image
Definition
Output produced from source images by processing, which should remain traceable to those sources. A derivative should remain connected to its source files and documented operations. Cropping, correction, enhancement and compositing can affect what the image appears to show.
- Context
- Image evidence
For example, an enlarged or contrast-adjusted image should remain linked to the original file and the operations used to produce the displayed result.
Processing cannot create unrecorded detail reliably. Retain originals and distinguish analytical transformations from presentation changes.
