    Ok, can someone please help me with this? It drives me nuts. I have an occasional crooked photo and want to straighten it. I rotate it until it looks good, which of course means it needs to be cropped to look straight. But when I try to crop, the crop is straight in reference to the photo (as in, it just follows the photo's angled side) so it's useless. I click on the side so I can angle the cropping frame, but often this does not create a perfectly straight line and leaves a little bit of a jagged edge. Is there a way to just make the cropping field straight, regardless of how turned the photo is? Thank you for any help, this annoys the hell out of me.

    Use the tape measure tool (it's shared with the eyedropper) and drag along the line you want to be horizontal. Then select Image>Rotate Canvas>Arbitrary Then just press ok. Tada. Done.

    I don't usually use photoshop for that, but when I did, that's how I did it.

    I think the OP is using the multi touch Trackpad to turn the picture, but he is not turning the Picture but the canvas!

    duoble click the picture layer , press Ok blah blah (so its not background layer anymore)

    select "show tranformation blah" , rotate the picture the way you want it (you can press cmd+r and drag down a guidline to help you) then use the Crop tool

    Done

    Do you mean Free Transform? I'm using CS3. How does rotating the canvas and cropping differ from rotating the Crop frame? You're still stuck with that pixel to pixel jump that gives not just what I want results.

    I Think what the OP is reffering to is that when he turns the pictures to straighten it, the Crop selection also moves... when you use a Multi Touch trackpad to turn the Picture, you are not not turning the picture itself but just the view.. its weird to explain :rolleyes:

    How to Straighten a photo.

    Too straighten a photo :
    Take the Ruler tool , draw a line on your photo that lines up with the element in the photo that you would like to straighten. Such as the horizon or a fence post.

    Then go to Image, Image Rotation, Arbitrary and click. Your photo is now straight !

    Next use your crop tool to crop to size and crop away edges.

    I cannot hold a camera straight , thats how I know this !

    Just to clarify (after looking) ^^^ The path is Image/Rotate Canvas/Arbitrary.
    That's in CS3.

    didn't want to start a new thread,

    but when i crop a picture using preview, the file size gets smaller, and isn't the same as the original. is it better to crop the photo in photoshop or it doesn't matter.

    i just want to make sure i get the same image quality.

    thanks!

    Most certainly better in Photoshop ! Photoshop will take care of up sizing the photo for you when you use the crop tool.
