To take this one step further, Nancy

In Adobe Photoshop CS2 there is a new tool Filter->Distort->Lens Correction that not only lets you set the rotation to straighten a picture (and fix barrel/pin corrections etc.), but lets you re-scale the rotated photo to fill in the "lost" corner areas that result from the rotating process. This is now my tool of choice for fixing crooked photos.

1. The original photo

2. The rotation tool (upper left), used to draw a straight horizontal line (bold red center) showing the resulting loss of pixels in the corners. The picture automatically rotates as soon as you finish drawing the axis (in this case horizontal) line.

3. Use the SCALE tool (bottom right of the sliders area) to scale the photo back up to fill the lost pixel areas (red borders).

There is a LOT of flexibility and manipulation capability in this new filter tool. I love it!

Brilliant! Is there anything comparable in PS6?

No, Maureeno. The filter is new to PSCS 2.

Have you checked out the thread below. It may be that the Lens Correction DOODAH Thingy wotsit, is not the best way to straighten images.

Thanks, Peter. I did see the post about problems using lens distortion filter to align. I can see a slight difference in the results of the two techniques.

An even easier way is to do the first step (measure tool) go to "Image/Rotate/Arbitrary" and it will have the exact measurement in there - no correcting +/-.
