In photography an “undoctored” photo need not be entirely free of “manipulations.”
Even the most trusted news photos — that is, the photos that are universally regarded as “undoctored” — typically undergo manipulations like conversion from raw to jpg, resizing, cropping, and color corrections.
Fortunately, there is a worldwide consensus about what changes can be made to a photograph without it being considered “doctored.”
That consensus made it easy for TCQ to build the complete list of those allowable changes into Q2, the qualification that checks whether a photograph is “undoctored.”
