Do you want to ensure that your photos are as accurate as possible? Then you may want to take the extra step to remove lens distortion. The technology is built right into Adobe Camera Raw so you can access it when developing RAW files. It can also be run as a filter in Photoshop (Filter > Lens Correction).
The tech is pretty easy and relies upon profiles for specific lenses and cameras. But where do these profiles come from? It turns out you can create your own or rely on the Adobe community to do the work for you. Here are two resources to check out.
Adobe Lens Profile Creator
The Adobe Lens Profile Creator is a free utility for creating your own lens profiles.The process involves shooting a test chart, then entering in some data about your lens and camera. The profile describes the types of optical aberrations that exist in a particular lens (such as distortion, vignettes, and color fringe). It then takes steps to correct the lens distortions in an image captured from the same lens. For more information read the following guide. Read more here (PDF, 1.64 MB). Download: Mac, Win
