Crooked horizons and distorted buildings can make an otherwise great photo, look amateurish. Luckily, LuminarAI makes it easy to level your horizon and fix perspective distortion with a couple of easy clicks.


CompositionAI
Open your photo in LuminarAI, switch to the Edit tab and select CompositionAI from the Essentials tools.
CompositionAI offers several options to manipulate your photo, including ways to easily straighten horizontal and vertical lines. In this article, we’ll focus on the two options in the Perspective section: Auto Horizon Alignment and Auto Verticals Straighten.
Auto Horizon Alignment
Click the first button in the Perspective section to automatically level the horizon. If the automatic setting needs refinement, you can move your mouse pointer off of the photo canvas to get the double-headed arrow and manually rotate your image if needed.
Auto Verticals Straighten
Click the second button in the Perspective section to automatically correct distorted verticals. If the automatic setting doesn’t fully address the distortion, you can use the Image 3D Transform sliders to fine-tune the results.
Horizontal and vertical alignment issues are common but with the help of LuminarAI and the CompositionAI tool, they are easy to correct. Taking a bit of time to straighten horizontal and vertical lines in your photos can make a big difference in the visual impact of an image and the perceived quality of your photography.

Hi Angela,
are these straightening functions present also in Luminar Neo? I’m concidering to move over to Neo, but I’m hearing very contrating opinions.. and this very topic is for me quite relevant. Many thanks
Hi Stefano – Luminar Neo has the auto option for horizon alignment under the Crop tool, and manual sliders to adjust vertical distortion under Develop > Transform. I hope that they add the auto “upright” option in a future update, but I don’t have any news on that at the moment.
OK, thanks for your super-fast feedback! I’ve kind of got used to this Luminar AI auto settings, though I sometimes need to use adjustment sliders in a second phase. I also notice that auto horizon alignment was more precise in L4 than it is in LAI, while Auto upright generally works well, maybe sometimes is too “drastic” and then I prefer to cancel and use the sliders, yes.
