General forensic principles apply when examining digital evidence. Different types of cases and media may require different methods of examination. Searching for keywords in videos, annotating specific portions of an image for detailed investigation, sharing evidence with other officers, magnifying, rotating, evidence, etc. are those features that can speed up the entire investigation process.
