Adobe Tutorial #4

Today, I did a tutorial over cropping with the perspective function in Photoshop. Check out the video here. It discussed how quickly and easily you can crop an image of a subject taken from an angle to appear to have been taken from straight ahead.






Here is the before image from the sample files provided by the tutorial: 

After you open the image, simply click on the crop tool and make a rough selection of the painting. Then, go up to the control panel and click the box labelled Perspective.












With this function active, you can now move each corner of the crop selection independently to make it fit the trapezoidal shape of the distorted image.











 Now, all that's left is to confirm the crop by either clicking the check mark or hitting Enter on the keyboard. That's it! Here's what you'll get!
