How to straighten buildings in Photoshop using customized grids and the transform tool

 

 

If you have ever photographed buildings, you have likely had to deal with the issue of distortion and imperfect perspective in your images. There are numerous ways you can deal with this, including the method outlined by Aaron Nace of Phlearn in the video below.

The technique involves utilizing custom grids inside of Photoshop, creating custom rulers and using Photoshop's Transform tools to adjust any horizontal and vertical edge in your image. By adding a grid overlay to your image, it is much easier to see what you are doing when making transformations to the image and you have a visual aid to allow you to easily line up your edges. Below, Aaron shows how to show rulers, use guiding lines and create custom grids. If you want to use a grid overlay to straighten buildings in your shot, you will want to go into your preferences and set up the grid to use pixels rather than inches. What pixel setting you want to select will depend on the size of the image you're working with.

Once you have your guide lines or grid set up, it's time to adjust the perspective of your image. To see how to use Photoshop's built-in transformation tools to straighten the buildings in your photos, watch the full video below.
