The four habits that improve phone photos of your work immediately: wipe the lens first, shoot in open shade rather than direct sun, get closer than feels natural, and hold the phone level rather than tilted down.

For before and after pairs, the one that matters most is standing in the same place twice. Mark the spot with a cone or a chalk line or just remember the crack in the driveway you stood on. If the after is shot from a different angle, the pair proves nothing and people can tell.

Take more than you need, at the time, while the job is finished and clean. Nobody has ever gone back a week later to photograph a driveway properly.
