For those drunk photos where the horizon skews for no artistic purpose, this is a quick and sure way to straighten the horizon.

1. In the tools pallet, select the ruler tool (it’s under the eye-dropper tool box).

2. Click and drag the image horizon that should be straight.

3. Edit > Rotate

Photoshop will automatically calculate the angle the image needs to be rotated, so just click OK.


Now just crop.
