#17 in a series of background briefs

How smartphone makers established a worldwide consensus on what constitutes a “doctored” photo — naturally leading to TCQ’s Allowable Changes list.

TCQ’s Allowables Changes list reflects
“A worldwide consensus”

In order to make their products appealing to buyers, the manufacturer of any camera or device will want to bake in in to the device as many automatic features as possible —

— but they will not want to make automatic any actions (in a device’s away-facing camera) that would be regarded as “doctoring” by users who just want to “take a photo to show what something looks like.”

That balance — embraced by all device manufacturers and billions of users — conveniently creates a list of seven allowable actions.

Those seven actions are #4 through #10 on the Allowable Changes list.

(For #1 through #3 on the list, see #1206.)

Seen another way, that list represents a worldwide consensus about what can be done to a photograph without having it be regarded as “doctored.”

That worldwide consensus explains why the Allowable Changes list is at the heart of TCQ’s definitions of “undoctored” and “doctored”—

— and why the Allowable Changes list is the centerpiece of Q2, the qualification that determines whether a photograph is “undoctored.”
