Hello Everyone,

I'm using CS 2. How do I tilt the horizon so that it's straight in a photo? I looked at the "Help" file in CS 2 but yet to find an answer.

Thanks a lot.

There are a variety of ways, but this tutorial will give you a good place to start.

Basically, with "image>rotate canvas>arbitrary" from the menu, and type in the amount of rotation.

But there's a neat trick for this: in your tool palette, see the eyedropper tool? Click that to get the flyout, and choose the ruler tool. Now use that tool to draw a line along the horizon, and then go to "rotate image"; the amount of rotation will be in the box already, just click "OK" :-)

To be unhelpful, I don't use this method any more, because you have to crop after the adjustment.

Now I typically drop a guide line in and use the perspective skew tools to drag one corner enough to straighten out the horizon.
Assuming I hadn't tilted at a crazy angle, this doesn't do much to soften out the pixels that are stretched and at the same time
preserves the image at the corners (because you don't have to crop in to the image with this method. I'm quite fond of the things
I compose in the corners, myself so like to keep them around.

This is what I do most of the time as well, but as you're implying it works best for incremental adjustments, plus it's not legal in basic editing. My sense of the OP, from other threads he's contributed to, is that he's an eager-to-learn neophyte, so it seems best to steer him down the convnetional paths for a bit.

Thats what I love about Lightrooms align tool - you draw a line along the horizon and it rotates and crops to the edges in one click.. job done. Not sure why CS4 hasnt implemented this, surely the Photoshop guys could walk down the corridor to the Lightroom guys and say..

"Hi, could we borrow the code that does that rotating/cropping thing.. cheers... oh and whilst we are here, can you show us how to do that `dragging the histogram` trick, because thats kinda neat as well".

Hello freakin_hilarious,

Thank you so much! Now my horizon is leveled!

Hello Bear_Music,

I'm learning so much from this photo site! I still have a lot to learn about Photoshop and it's capability. I hope to learn how to use layer one day.

Thanks!

And so you dont spend ages getting the PERFECT degree measurement using the 'arbitrary' method, you can do it a whole lot easier by using the 'measure' tool.

Zoom in on the horizon (or any other straight reference point) at about 300%, get the measure tool and draw a line over the horizon with it, then go to image>rotate>arbitrary and it will have already filled in the degree amounts for you and the direction also. This way Photoshop straightens the line for you. I get measurements like 0.713 degrees with this and it works perfectly when something doesn't look quite right.

That's what I told him to do in the third post :-) Although not the zoom part, actually...
