Match Colors Across Photos
Align an entire shoot to one reference frame — white balance, exposure and contrast — as reproducible parameters.

Pick one frame you are happy with, and every other photo is aligned to it. This is the problem that actually costs time on a wedding, event or product shoot: not making one photo look good, but making eight hundred look like they belong together.
A common misconception is that batch grading means applying one LUT to everything. It does not work, and the reason is worth understanding: each photo starts from a different exposure and white point, so a single fixed mapping preserves those differences rather than removing them. Alignment has to be computed per photo, from that photo's own statistics.
Everything is expressed as parameters — channel gains, an exposure offset in stops, a contrast gamma — never as an arbitrary pixel mapping. Histogram-forced matching would be more aggressive, but it produces a transform that cannot be written to XMP, cannot be reproduced in Lightroom, and cannot be audited.
