Photoshop Tutorial- Fixing Perspective

Filed under: Landscape,Photoshop Tutorial — Tags: , — Harold Stiver @ 7:00 am

Original with "tipping" Boathouses

Yesterday I posted some images of these boathouses from Port Rowan. I mentioned that I had fixed the prospective. Above is the original with buildings on a slant towards the edge of the frame. This is due to the nature of how light hits the sensor or film through a standard lens. There are Tilt/Shift lens designed to correct this problem but they are not in most people’s camera bags.

While often the whole image is selected for correction, we are just going to work with the buildings. First we give ourselves room to work with by adding canvas all around the image (Image 2).

Then we use the Rectangle Marquee tool to select the portion above the post. If we right click on the selected portion, we can choose “Free Transform” from the menu, and another right-click allows us to choose “Skew”. We now grab the corner handles on the selection at each top corner and drag them inward, and drag the bottom handles outward,  until the side of the buildings are vertical (Image 3). When satisfied, double-click or press enter.

We crop the image to eliminate the border and do a bit of touch ups like cloning in the small empty triangles from the corrected portion and are image is ready (See final image below)

  4. […] This Ukrainian Catholic Church with its complex patterns seemed a good candidate for a HDR (High Dynamic Range) treatment. It also required a Fix in the Perspective. […]
