Lightroom: Lens Correction and Perspective Correction
Adobe Photoshop Lightroom provides users with ways to make their photos better. Two ways that Lightroom improves photos is via the Lens Corrections panel and Perspective Correction Feature. The Perspective Correction feature allows users to fix user errors while the Lens Corrections Panel corrects any issues with user's camera lens.
Step 1: Lens Corrections Panel
The Lens Corrections panel allows users to profile the lens that they are using and fix any abnormalities associated with that lens. Users can profile their own lens via Adobe Labs' Adobe Lens Profile Creator. Users simply need to download this free software and plug in the information about their camera lens. This way, the exact profile of the lens will be created in Lightroom.
Lens can be profiled in two ways. If a user's lens is already a part of the Lightroom's lens profile, then users simply need to check Enable Profile Corrections. Then, the image will be corrected based on the lens abnormalities (EXIF data) associated with that camera lens.
If a user, however, created their own profile data, the Adobe Lens Profile Creator will add that lens' EXIF data to Lightroom. From here, Lightroom will make the necessary corrections.
Photographers can also see how an image will look through other lenses if they wish. They simply need to change the Lens Profile information to the settings for other lenses.
Users can either allow the program to automatically adjust the quality of the pictures. Or, they can use the Amount Sliders to adjust the intensity of corrections. Modifications can be made to Distortion, C. Aberration and Vignetting.
Step 2: Adjusting Perspective
Within the Lens Correction panel, there is a Manual mode. In the Manual mode with the Transform slider selections, users can further adjust lens problems. For example, using the Distortion slider, users can manipulate their photos until they bulge inwards or outwards. Images can also be rotated and scaled up or down. Users can also manipulate colors with the Chromatic Aberration sliders.
Within the Transform sliders, there are two other sliders, one for Vertical and one for Horizontal. These two sliders help users compensate for issues with lens perspective. For example, if a photo was taken at an angle, the subject of the photo could be crooked. Or, if a person didn't have a wide angle lens, and they had to take a vertical shot horizontally, they may want to flip that photo. This is where these two sliders come in handy.
Users can simply move the sliders back and forth until they correct the image's perspective. But, photographers should only manipulate one slider at a time since using both could cause the perspective to get worse, not better.
Users may have to do a lot of experimentation to get their photos in the right position and correct any issues. But, since this Lens Correction panel is located within the Develop Module, users don't have to worry about messing up their original image. Any corrections done within the Develop Module won't be applied to the original photo.
