Do I need to mark the sky before describing?
No! Just describe what sky you want: 'replace sky with sunset' or 'change to blue sky with clouds.' The AI automatically detects where the sky is. Only use markers when you need precision around complex edges like tree branches or intricate architecture.
How do I replace the sky in a photo for free?
Upload your photo to EditThisPic, type what sky you want (like 'replace sky with dramatic sunset'), and click Generate. The AI handles sky detection and blending automatically. No Photoshop or manual masking required. Free to try with no signup.
Will the new sky look realistic or obviously edited?
The AI automatically blends the new sky with your horizon and adjusts foreground lighting to match. When you specify lighting that matches your scene (e.g., 'sunset with warm light from the right'), results look completely natural. The key is matching the sky's time of day to your photo's existing shadows and light direction.
Can I replace the sky in photos with buildings or trees?
Yes! The AI detects complex edges like building outlines, tree branches, and mountain silhouettes. For intricate details like fine branches or power lines, you may need to tap a few markers along those edges for perfect results, but most architectural and landscape photos work on the first try.
