Lightroom Mobile – Use the Geometry Function to Correct Distortion
Struggling with distorted lines in your photos? Lightroom Mobile’s Geometry function is a game-changer! In this video, learn how to easily correct perspective distortions, straighten lines, and achieve a polished, professional look—all from your smartphone. Whether you’re editing architecture shots, interiors, or group photos, this feature ensures your images look just right. Watch now to see how it works!
This video is from our Lightroom Mobile Course.
Video Summary:
This tutorial explores the Geometry tool in Lightroom Mobile for correcting perspective distortion, using a photo of a room with tilted lines as an example. The host demonstrates the trade-off: the Auto function perfectly straightens lines but crops the image heavily, often removing important elements (like a client’s refrigerator). To preserve content while still correcting perspective, the Guided Upright tool is introduced, allowing manual drawing of lines to define what should be straight. The video also covers other adjustments like Vertical correction, Rotation, Aspect Ratio, and Scaling to fine-tune the result. The final challenge—white edges created by the correction—can be addressed by either cropping (losing some image) or, ideally, by exporting to Photoshop to use the Content-Aware Fill tool for a seamless fix, preserving the maximum image area.
Timestamps:
0:30 – The Problem with Auto: Using the Auto Upright function perfectly straightens lines but results in heavy, undesirable cropping, removing key elements from the frame.
1:23 – Introduces the client’s perspective: Sometimes content is more important than perfect technical correctness.
2:03 – Alternative 1: Vertical Upright: Tries the Vertical correction. It straightens better than auto but leaves white edges due to perspective warping. Enabling Constrain Crop helps but still crops significantly.
3:16 – Alternative 2: Guided Upright (Recommended): Resets and uses the Guided tool. Manually draws lines along the refrigerator and door frame to tell Lightroom what should be straight. This provides a good balance of correction and content retention, though white edges remain.
4:25 – Manual Fine-Tuning: Explores additional sliders for Distortion, Vertical/Horizontal Shift, Rotate, Aspect Ratio, and Scale to further adjust the corrected image.
5:48 – Solving the White Edge Problem:
* Option 1: Use the Crop tool to trim the edges, sacrificing some image area.
* Option 2 (Ideal): Export the image with white edges to Photoshop and use Content-Aware Fill to seamlessly reconstruct the missing areas, preserving the full composition.
