How to Straighten Crooked Images Fast Using Lightroom

06 Jun

If you’re like me, it’s so easy to get focused on trying to take great shots that you forgot to make sure your images are straight, and not crooked. Not some crazy tilt, mind you – just a slight tilt. So slight that when you notice it in your images, it just looks weird. A more dramatic tilt and we’ll just call it art. But this slight tilt is just enough to drive you crazy and cost us a lot of extra time editing your images.

Well I am here to report that I have found a quick and easy way to fix this tilt fast using Lightroom. So easy, that you can even automate it so that Lightroom fixes it for you.

So if this tip interests you, keep reading to find out how:

Image01

Take a look at the image above. Good shot, right? Photographically I think I did well with the image, but it’s crooked! I can’t give this image to my client like this, it needs to be straightened first.

Lens Corrections Panel

Beginning with Lightroom version 5 the Basic tab was introduced inside of the Lens Corrections panel. This tab gives you the easy to use Upright Mode buttons, which are powerful tools used to fix perspective issues with your images. The perspective issue that I always seem to be dealing with is crooked images.

Image02

There are several Upright Mode buttons, but the one I want to show you in this article is the Level button. When clicked, this button works to straighten your images based on the lines present inside them. Obviously if there are no strong vertical or horizontal lines in the image, this button won’t work. But if there aren’t strong lines, who’s to say it’s crooked in the first place, right?

Images appear crooked to our eyes because of the strong lines within an image, therefore the Level button works great at straightening those images quickly, without much difficulty. Instead of going into the crop tool and manually rotating the image slightly to straighten it, I can go to the Lens Corrections Panel instead and click the level button to straighten this image very quickly.

I also like to have the Enable Profile Corrections check box checked as well as the Constrain Crop check box. These make sure Lightroom is straightening with as much information as possible.

Automating Your Upright Adjustments

Now here is the trick. When done properly, you can create a Lightroom preset, or sync your Level adjustment across any number of images, and have Lightroom analyze and adjust each image independently based on each image’s needs and requirements.

What this means is you can have Lightroom straighten all of your crooked images with the click of a couple of buttons!

Syncing

In the Sync dialog box under Lens Corrections check box, there are three check boxes you want to be concerned with: Upright Mode, Upright Transforms and Transform.

Image04

These three boxes determine how Lightroom is going to handle your straightening – whether to analyze each image independently or simply copy the same settings from one image to the next.

If all three are checked, Lightroom will simply apply the same setting to all of the images, something you do not want because each image requires specific straightening based on its own lines. You’ll notice that Upright Mode is grayed out, telling you that it isn’t active.

Image05

To do what you want, which is to have Lightroom analyze each image independently and straighten it based in its own needs, you want to ONLY have a check mark in the Upright Mode box. The other two are left blank (see below).

Image06

By doing it this way, Lightroom will fix your crooked images, according to the amount of straightening that each image specifically needs.

How cool is that?

Take a look at the images below. I took many shots in a sequence of the couple walking, and I want to straighten each one individually. Before learning this technique, I had to straighten each image individually – but not anymore.

Image07

Once I fix the first image using the Level button in the Lens Corrections panel, I can then sync the Upright Mode across all of the other crooked images, and each will be analyzed and fixed according to what it needs (even if they are all different amounts).

Image08

Look at that. All of my images were fixed with a few clicks. I don’t want to belabor the point here, but I constantly shoot crooked and this little trick saves me hours of tedious straightening over the course of a year.

Making a LR Preset

You can also automate this process by creating preset. You do this by first straightening an image with the Level button found in the Lens Corrections panel of the Develop Module.

Then, at the top of Presets panel clicking the (+) plus button to create a new LR preset.

Image09

This will bring up the New Develop Preset dialog box where you choose which settings you want in your preset, the folder you want to store it in, and what name you want to give it. Name your preset something that you will remember, put checkmarks in the Upright Mode checkbox and the Lens Profile Corrections checkbox and hit Create.

Image10

Now, when you have crooked images you can hit this preset and almost magically, your images will be straightened compared to the strong lines in the image.

Image11

Give it a shot, I think you will find yourself using this technique quite often to straighten your images quickly.

How to Straighten a Crooked Image in Photoshop

Straighten an image in Photoshop

While most photo editing programs have a dedicated and easily discoverable Straighten tool, Photoshop does not and never has had. Instead, prior to Photoshop version CS6, it was notoriously difficult to straighten a photo.

This all changed with the new Crop tool in Photoshop CS6 and CC, and it is now much easier to straighten an image – even if it isn’t easy to determine that the Crop tool is how you do it.

I’ll show you how to straighten a crooked image in Photoshop, but before we look at Photoshop CS6 & CC let’s take a trip back in time to see how to straighten an image in Photoshop CS5 and earlier. Of course this process still works in later versions of Photoshop as well.

Straighten an image prior to Photoshop CS6 & CC

With an image open in Photoshop locate the Ruler tool which shares a toolbar position with the Eyedropper tool.

Click and drag along some element in the photo that should be either truly horizontal or vertical. The longer the line you make, the more accurate the adjustment will be.

Once you have the ruler line positioned along the line you wish to straighten, choose Image > Image Rotation > Arbitrary and the dialog will show the angle of that ruler line – in other words the angle to rotate the image to straighten it. Press Ok to rotate the photo and straighten it.

Choose Rotate Canvas to rotate the canvas to the selected angle.

In Photoshop CS5, the process was streamlined slightly by the addition of a Straighten Layer option which appears when you select the Ruler tool. Once you mark out the line to straighten to you can then click this icon to straighten the image (see image below).

Click Straighten Layer in Photoshop CS5 and later to straighten using the Ruler tool.

Straighten using the Crop tool

In Photoshop CS6 and CC the Crop tool now has a Straighten tool built into it. So, to straighten a photo, click the Crop Tool (or press C) and click the Straighten icon on the toolbar.

Click Crop and then click the Straighten icon on the Tool Options bar

Now drag a line across the photo, along an element which should be horizontal or vertical.

When you let go the mouse the image will be rotated automatically using the line as a guide and the resulting uneven edges of the image will be cropped away.

Press Enter to confirm the crop

Press Enter to confirm the crop. If you have the Delete Cropped Pixels checkbox enabled then the excess image will be permanently removed.

The Delete Cropped Pixels setting lets you choose whether cropped pixels are deleted or not

If the Delete Cropped Pixels option is unchecked, the canvas will be reduced in size to match the crop rectangle and the extra image pixels will disappear from sight but will still be accessible.

At any time you can reinstate these hidden areas of the image which lie outside the canvas by choosing Image > Reveal All.

Use Reveal All to display contend hidden when  you crop
