    Do you mean straighten a crooked horizon, or level a bowed horizon (cause by wide angle lens)?

    To straighten a crooked horizon:

    * Open photo in CS3
    * Use the ruler tool (located under the eye-dropper tool in the pallette)
    * With the ruler tool click on the horizon, hold the mouse down and draw a line along the horizon (or the thing that should be level), and then release the mouse button.
    * Go to Image > Rotate Canvas > Arbitrary. (the degree of change will already be set from your ruler tool).
    * Click OK, then crop the newly rotated photo.

    Bowed Horizon:

    *Open photo in CS3
    * Filter > Distort > Lens Correction
    * Use remove distortion slider.
    * Click OK when done.

    I find the quickest and easiest way in CS3 is as Rick mentions .....go straight to Image > Rotate Canvas > Arbitary......too easy

    Folks,

    Just an additional note:

    The ruler tool can also be used to measure the angle that a near-vertical line, say a wall, is offset from the vertical. Photoshop is smart enough to recognise that near vertical lines should be vertical. It will then calculate the required rotation to make the line vertical.

    Cheers,

    i also find the warp tool very good(edit>transform>warp) This is especially good with a stitched pano where the horizon may go up and down after stitching.

    If its to straighten the horzon, I've tried Rick's suggestion before but find that my eyes get lazy and I'm just guessing the straightness.

    So I enable grids and rotate my image/canvas according to the lines. Much more accurate!

    I am using version 2.2 Roof. In 2.0 - 2.2 is under the crop tool in the develop module, up the right side, just under the bottom left of the histogram. In 1.0 - 1.4 it was along the bottom, under the image window, I can recall exactly where. If you still can't find it Roof, I might be able to do some screen shots to show you.

    I never knew how to straighten the photos either so what I done was use the crop tool and rotate until where you want it. I figure you have to crop after straightening so do it in one go.
    Thanks for looking....Cheers,

    Yeah same here - searched in google first and the most easy-to-follow procedure was the crop method

    Thanks for the tips!
