Squaring tutorial..


Original Image
 

Select Measure tool
 

Pull a line that should be horizontal, or vertical.

Choose rotate, arbitrary
 

Photoshop figures out how much to rotate to make your pulled line ortho. (either perfectly horizontal, or vertical)
 

Done!
I dunno how common this knowledge is, But its one of the more obscure tools I use in Photoshop, and Id like to share it with you, hopefully it may come as new information to some of you.

Okay.. Going from the top of the images, First.. A nice shot of the Eiffel tower, but its a little crooked. This tutorial will tell you how to have Photoshop decide best adjustment angle (eliminating all the guesswork.)

First, you need to choose the measure tool..
Then use the tool to pull a line on your drawing that follows what should eventually be either a vertical, or horizontal line.

Photoshop will take this measure line and rotate the image to make the line either perfectly horizontal, or vertical.

Choose Image - Rotate canvas - Arbitrary

PS will give you a number (this is the amount, and direction PS will rotate your image to make your measure line square)

Apply the rotate, crop out the exposed canvas, and Viola! Your image is now perfectly square and even!

Hope I wasnt too confusing.. This is the first tutorial Ive done.

Cheers!

Good one!

Probably the only thing I would have done differently is pick my line. While the tower is the longest vertical line, it isn't well defined. I would recommend using one of the well defined horizontal lines...like the curb, or one of the horizontal levels on the tower itself.

A couple of things...if there aren't any defined lines, how do you know it isn't straight?

Next, make one up.

Or, rotate it a degree or two at a time until you get what you want.

Great tip. It's something I use so often I don't even think about it, and I remember when I first learned it that it wasn't obvious.

By the way, you stopped just shy of "Done". Don't forget to crop.

Thanks for putting that together Jason. I know I've got quite a few tilting horizons that need to be fixed on my pictures.

Great tutorial. I always just rotated by eye, and try to get my images as squared as possible.

Here's a little program that can come in real handy for lining things up. It's external to image editors but is always on top so it works well.

Great tut, A small tip to add:

A lot of times, when zoomed out a fair amount in photoshop, the edges of the crop tool will "cling" to the edge of your canvas. This can be frustrating if you want to do a quick crop, leaving out just the slight rotated portions. You can use the rectangular marquee to make a selection around the parts of your image (this will not cling), and then crop by going to 'Image >> Crop.'

new info to me, I always did it by dragging out a guide line, and then rotating based on that line =P This is a bit easier.

And cletus, you can turn off the "cling" which is called snap by going to view>snap, or pressing ctrl+shift+; =) Sometimes snap is your best friend and sometimes your worst enemy

Thanks so much-new to me, and I was also wondering why I was having so much trouble cropping, so have enjoyed all posts!
