What are the rules on photo manipulation in journalism?
Strict, and stricter than most people expect: news photography operates on the principle that an image must accurately represent what was in front of the camera, and the permitted edits are limited to what a darkroom could once do to a whole frame.
What is generally permitted:
Cropping, provided it does not change the meaning — cropping out context that alters what the picture shows is a breach even though nothing was added.
Global adjustments to exposure, contrast and colour balance, applied to the whole image and only to the extent needed for accurate reproduction.
Dust and sensor spot removal.
Conversion to black and white, where disclosed as a stylistic choice.
What is prohibited:
Adding or removing anything in the frame, however minor. Photographers have lost their careers over removing a small distracting object.
Selective local adjustment that changes emphasis — darkening a background to make a subject more dramatic is treated as manipulation by major agencies.
Combining frames, or staging.
Directing subjects to recreate an event, without disclosure.
Misleading captions, which is the most common failure of all — an unaltered photograph presented with wrong or implied context misleads more effectively than a doctored one, and attracts less scrutiny.
Why the rules are absolute rather than proportionate. Photography's authority rests entirely on the assumption that it records reality. Permitting small manipulations would remove the basis for trusting any of it, so agencies enforce a bright line rather than a judgement about materiality.
How breaches are detected: examination of the original raw file, metadata, and error level analysis; agencies require photographers to retain originals precisely so this is possible.
What generative AI changed. The old assumption that a photograph records something has broken. Major agencies and publishers have banned AI-generated imagery in news content, require disclosure in illustration contexts, and are adopting content provenance standards that cryptographically record how an image was captured and edited — an attempt to rebuild the guarantee that the medium itself used to provide.
Illustration and opinion contexts allow more, with clear labelling.
