GIMP

GIMP has been the free answer to a paid image editor since the nineties, covering retouching, compositing, painting and format conversion, with scripting for the jobs you do a hundred times. Its colour management is strong enough for print work. The interface is its own rather than a copy of anyone else's, which is the real cost of switching to it.

There is no pricing page because there is no price. GIMP is free software under the GPL, funded by donations and volunteer work, and every feature is in the one download with no paid edition above it. Support is community forums and documentation rather than a company, which is the practical difference from a paid editor. It works alongside Scribus and Inkscape for layout and vector work, which the project recommends as the free equivalent of a design suite.

Anybody who needs a full image editor and either cannot or would rather not pay a subscription for one. Somebody whose muscle memory is built on Photoshop should know the interface is its own, and that relearning it is the actual price here.
