Auto Straighten is now 5x more precise in Photomator and Pixelmator Pro
Photomator and Pixelmator Pro have significantly improved the Auto Straighten feature, making horizon detection 5 times more accurate in both apps. This powerful enhancement allows you to straighten photos with a single click, saving you time and effort, especially when editing large batches of images. Whether you’re a professional photographer or a casual user, we believe you’ll find the improved Auto Straighten tool essential in your photo editing workflows.
5x Better Horizon Detection
Good composition is essential for creating beautiful images – even a slightly tilted horizon can make a photo look less professional. That’s why automatic photo straightening is so important. To make it even better, we developed our own AI-powered Auto Straighten algorithm from scratch. Now, Auto Straighten is 5 times more accurate in detecting the horizon and straightening photos, ensuring your images look their best with just a click. We are thrilled to celebrate this significant improvement, making it easier than ever to achieve perfect composition effortlessly.

Auto Straighten powered by AI
Auto Straighten is now 5 times more precise, thanks to our completely redesigned horizon detection algorithm. Previously, we relied on the horizon detection technology provided by the Apple Vision framework, which worked well for images with a clear horizon line. However, it often struggled with more complex images, leaving them unlevel even when they were visibly off. This limitation highlighted the need for a more accurate solution, leading to the development of our custom machine learning-based horizon detection technology.

Traditional approaches
The Hough Line method is one of the most widely used techniques for straightening photos. It works by recognizing shapes in an image, such as lines, making it effective for straightening images with a clear horizon. However, this method has limitations – when the horizon is obscured by objects like mountains, hills, or trees, the algorithm often fails to straighten the photo accurately. This highlights its lack of precision in more complex scenarios.
The new machine learning approach
To develop the Auto Straighten feature, we trained a machine learning model based on the EfficientNet architecture. Instead of searching for shapes like lines, the model considers the entire image when determining the horizon. It was trained on images depicting complex scenarios where the horizon is not easily identifiable as a straight line, as well as those taken in dark settings. This approach enables the tool to straighten photos with clear horizons and those with more complex compositions, such as images featuring mountains, trees, and other elements.

To prepare Auto Straighten for even tougher scenarios, we trained the model using photos with varying noise levels and high compression. This enhances the tool’s versatility, enabling it to effectively straighten noisy and compressed images. As a result, Auto Straighten now delivers consistent results even with lower-quality photos.

Batch editing in Photomator
You can use the improved Auto Straighten feature for individual photo editing, but it’s especially valuable for batch editing. Straightening photos, even from a small photoshoot with, for example, 50 images, can quickly become tiresome. Now, batch auto-straightening is also 5 times more accurate, delivering more consistent results. When batch editing in Photomator, make sure to include Auto Straighten in your workflows to enjoy automatic, precise results in seconds.
