Do I need to mark the sky before replacing it?
No! Just describe the sky you want: 'add a sunset sky' or 'replace with blue sky and clouds.' The AI automatically detects where the sky is in your photo and replaces only that area. Use markers only if the AI has trouble with complex edges like trees or unusual horizon lines.
Will the lighting on my subject match the new sky?
For best results, include lighting instructions: 'with matching sunset light on the scene' or 'midday lighting on the ground.' The AI can adjust foreground lighting to match the new sky mood, but being explicit about this in your prompt ensures better results.
Can I use a specific sky photo I have?
EditThisPic generates skies from your description rather than accepting reference images. However, you can describe skies very specifically: 'dramatic orange sunset like Arizona desert sky' or 'soft pastel Hawaiian sunset.' The AI creates beautiful skies matching your detailed description.
Why do tree edges look rough after sky replacement?
Tree branches create very fine edges that are challenging to separate from the original sky. Use the refinement step with markers on problem tree areas. Try adding 'blend naturally through tree branches' to your prompt for better edge handling.
Does this work with photos that have no visible sky?
The photo needs some visible sky area to replace. If your photo is entirely indoors or has no sky visible, consider using the 'extend photo' tool to add sky above the current frame, or the 'add background' tool for complete scene changes.
