Fotoblekkaus

Fotoblekkaus is a technique for obscuring parts of an image by blocking, masking, or replacing regions with solid colors or patterns. The term is used in Finnish media and image editing to describe a controlled redaction of visual information while keeping the overall composition legible. It is commonly applied to protect privacy, sensitive locations, or classified content in photographs and video frames.

Common methods include pixelation or mosaicing, where the affected area is replaced by a grid of enlarged picture elements; blurring, which softens detail; and masking with solid color blocks or patterned overlays. More advanced approaches substitute the obstructed area with a synthetic patch, such as a neutral color or an asset from a stock image. The choice of method depends on the need to hide exact identity, the desired aesthetic, and the publication's standards.

Fotoblekkaus is used by news media, courts, research institutions, and social platforms to comply with privacy laws and ethical guidelines. It is distinct from simple retouching in that it prioritizes non-reversibility or controlled concealment, though many methods are reversible if not applied carefully. Best practices include documenting the alteration, avoiding over-blocking, and ensuring that essential context is not compromised.

Ethical considerations emphasize consent, especially with minors, the public interest, and avoiding misrepresentation. Authors should balance transparency about edits with respect for privacy and safety.
