Correcting Keystoning

Learning

Dec 17

Keystoning is the term used to describe the "Leaning Tower of Pisa" effect of converging lines in architectural renderings. it's a very common result when rendering with a wide-angle lens. Photoshop can oftentimes straighten those buildings for you, correcting this perspective problem in a matter of seconds

Open your rendering in Photoshop, select the Crop tool from the toolbox, and drag the cursor from the top left corner to the bottom right corner and release. You will see the "marching ants" around your entire rendering. Go to the lower menu bar at the top of the screen and check the small box next to Perspective. Now, using the cursor, drag the top left corner of the marching ant border into the rendering so that the border is parallel to the tilting structure in the rendering. Do the same thing on the right side of the rendering. Then, double click in the rendering just to the right or left of the small center circle that appears on the rendering. Photoshop adjusts the image so that any tilting lines appear truly vertical, as they do when the human eye views the actual scene.

Hey there, thanks for visiting my online portfolio. My name is Bobby Parker and I’m a Minnesota based illustrator who specializes in photo-real architectural renderings, and I’m not afraid to turn my hand to animation if the job requires it. While growing up in Illinios I always had a childhood interest in drawing and artwork that has stayed with me throughout my career in architecture. I received my architectural education working for some of the most talented architects in Chicago. I’ve worked on a wide range of projects, and pride myself on the ability to deliver a valuable and visually-appealing end product, no matter what the scope. For me, it’s essential to achieve a balance between quality and speed. 24 years after working professionally, I am still combining the fundamentals of art with the most current industry technology, to create incredibly realistic 3D architectural renderings. I love what I do, and I hope that it shows in my portfolio. Please take a minute to visit my work page and drop me a message if you have any questions
