How to Straighten an Image in Photoshop

[Kampar]

I know there are a couple of these on-site already (and very good they are!) but I thought for the sake of completeness I'd put one together too in the same PDF format as my other tutorials.

Note that this shows just one method of straightening an image (it works perfectly almost every time for me) but there are others. Also, I believe PS CS/CS2/CS3 have slightly different looking toolbar options for the measure tool but you should be able to use this guide in each of them.

Have fun (well, as much fun as you can when straightening something up anyway)!

Nice tut, you haven't mentioned that you created a copy layer to work on, so it confuddled me when I saw the rotated image later on. :)

Is it worth mentioning also that each part (back,front,spine) should be checked independently before re-assembling into the template as often distortion can throw one side out more than the other?

[Kampar]

That's in the next tutorial ...

I think there is a mention in there of duplicating the background layer to do the rotation ... check it out!

Another nice tut but one trick I learned in PS is instead of having to type in the value using the transform function, just use the rotate, canvas, arbitrary and the angle of rotation will already be there. I think CR actually taught me that one...d*mn b*stard actually used to know a few things before becoming a shout wh*re!

>>just use the rotate, canvas, arbitrary

Yep - you could do that too. But even in the method in the tutorial you don't have to type the rotation angle in, the measure tool still puts it in automatically for you you just have to change the plus/minus sign. So its a question of which route you prefer to get the rotation done!

[Edit] - actually, thinking about this more, maybe the reason I do it this way is that I sometimes use the same method in a layered file and you only want to rotate the one layer rather than the entire canvas. So I guess it's too difficult for me to remember two different ways of doing this!

CR also has a nice trick where instead of duplicating the background layer you just turn it into a normal layer and rotate it ... but it was easier for me here just to say duplicate layer (as you're going to throw the file away later anyway!)

Yeah, I guess I was just referring to working with a raw scan image with no layers (since I usually straighten the cover just after I change it to 300 dpi).
