Designers, production staff, and photographers will discover quick and accurate evaluation and correction techniques to speed up their workflow in the fast-paced production environment.

Okay, now that we have covered the Dimensional Resolution, Linear Resolution, Interpolation, and then saving out in proper file format, either TIFF or .PSD. If we are going to be working on the file more, let's address that whole issue of straightening up your horizons. So let's go ahead and open up this Homer Beach image, which is a nice composition but boy, that horizon line, in this case it's the water/land horizon. Because the top of the land/air horizon is not as obviously off, because the topography itself is so irregular. But clearly the water land horizon is off.
So once again as always, we'll make a duplicate copy, and in this case we'll just call this the Rotated Version. Rotating on a horizon is easy. In Photoshop CS4 there is actually a Rotation tool. Just go R for Rotate and then you can nondestructively rotate your image to say hey, what does that look like? But you can actually take a look at how you want your horizon to go and you can watch your rotation angle right up here as well. The other thing you can do is get the little scrubby tools, that you can just rotate it like this, if you prefer to do it that way, and then you can just reset the view so it goes back to the original.
To make your correction what we are going to do is actually go to our Info tool, and we are going to go to the Ruler portion of this Info tool. Remember, when there are multiple tools here, you can just keep toggling on the Eye tool until you get to the tool that you want, in this case the Ruler tool. This really is simple. You just click on one end of the horizon, and while you hold, don't click and then let go, just click and drag and just move down to the other side, and you will notice up top here, just watch the angle number right there. Just be careful, don't over do it here. Notice it's about -1.8?, and then release.
Then before you do anything else, come up on the image, and go underneath Image Rotation and choose Arbitrary, and a more accurate version, 1.77, what it actually was, will come up and then you just click OK. Now, notice when you do this, pixels are added in various places, because in Photoshop you can only work with Square Dimensional Images, or Rectangular Dimensional Images. So now you have to move to your Crop tool, C, and you have to pull this down here, make sure that you don't get any of the outside white pixels, or you have to do this again, and then click Enter.
Once you have accomplished that, then you can see that your horizon is nice and straight. If you need to go back to the original image at any point, you can, because you have done this on a copy of the image. So it works just like a champion, it's really easily done. Let's just do another one quickly just to show you how fast it can go. You just take your Eyedropper tool, drag this along the horizon, come underneath the image. If you have to do this very much, of course you can just assign a keyboard shortcut to that Image Rotation and then Arbitrary, and then just go right to the Crop tool. C for the Crop tool, this is where being able to swap tools quickly and easily really comes in handy.
Then just hit Enter, therefore your horizon line is nice and straight. All right, so that's it. That's rotating images using the freehand rotation, just so you can preview, and then the Info tool, the Rotation tool to help you get a good accurate rotation.
