Colour Correction
By the end you can read a histogram aloud, where the light lives, what is clipped and at which wall, what the photo needs first; correct a photo in one fixed order, white balance with the neutral picker, levels, a gentle curve, saturation last and least, each on its own named layer; write a note a client could read, wrong, did, why, with the histogram as the evidence; run an auto-correct as a rival draft and beat it by hand; direct an AI critic with evidence and verify every suggestion on the instrument; and export a before-and-after pair under one stem with the XCF beside it.
