A product catalogue that wanted left-facing shoes
You've just shot fifty pairs of running shoes for an online store. The template the design team gave you wants every shoe facing left, but half your shots came out facing right because of how the lighting was set up. Re-shooting is out of the question.
You drop all twenty-five right-facing photos onto the page, toggle Horizontal, and watch the grid flip in unison. The previews update instantly so you can sanity-check that nothing went strangely orientated, then you click Apply and grab a single ZIP of flipped JPGs.
The shoot stays on schedule. The template fills up with cleanly oriented product shots. Nobody can tell you didn't redo half the day.
