Lightroom Lens Corrections


Post 22
Series: Introduction to Adobe Lightroom®

Out-Smarting Common Errors
There are common optical errors that camera lenses can create. Lightroom provides a unique resource to correct these issues and options for further creativity with Lens Corrections.
Distorted View
Distortion, vignetting, chromatic abberation, and perspective correction can be done in Lightroom without making any changes the original image. Lens corrections can also be copied from one image to another, applied to many images at once, or even set up as part of your import template. All of these uses can save a great deal of time.
Lens Correction is a great tool, but it doesn’t work for every situation, for every lens, and so on. You will need to test out what this tool does for you and your images.
Correct!
 
This tool is most useful for images with strong lines such as those found within architecture and some landscapes. Under Lens Corrections, in the Basic section, click on the box next to Enable Profile Corrections. (If you have an older version of Lightroom and do not have a basic sub-section here, look under “profiles”.)

 
Does your image change?

 This will not be easy to see, but the lines of the bricks and the window in this
 image are now straight, rather than slightly concave as in the first image.

Need to remove chromatic abberations? Check the box next to Remove Chromatic Abberation.



(See Constrain Crop below.)
The Off, Auto, Level, Vertical and Full buttons are used to apply a quick horizontal or vertical level adjustment to your image. So you know, Off is the default setting. Start by clicking on Auto. This might be all your image needs. If you want to adjust more, try the Level, Vertical and Full buttons.

Constrain Crop changes the aspect ratio of the image. After adjusting the aspect ratios, sometimes the edges of your image are pulled in, leaving white space. Constrain Crop cuts our the white edges. 


Apply the Upright and Reanalyze buttons when your image seems a bit off.

Customized Distortion

Your particular make of lens might be known for consistent visual errors. See how you can aconsistently adjust for that in the next post.
