Double Exposure: FAQs
What is a double exposure effect?
A double exposure blends two images into one — classically, a second scene appears inside a subject's silhouette (like a face filled with a cityscape or forest). It's a striking, artistic look popular for portraits, album covers, posters, and ad creatives.
How do I make a double exposure online for free?
Upload your main photo, open the Double Exposure tool, then add a second image (upload your own or pick from Unsplash). It's automatically blended inside your subject's shape. Adjust the blend mode, opacity, and position to taste. Your first edit is free with no watermark.
Which blend mode should I use?
Screen and Lighten work best when your subject is dark (they let the bright parts of the second image glow through) — that's the classic look. Multiply works better on light subjects. You can switch modes instantly and pick whatever looks best.
Can I control how strong the effect is?
Yes. An opacity slider controls how much the second image shows through, and you can position and zoom the inner image to place the scene exactly where you want inside the silhouette.
Do I need Photoshop or design skills?
No. Everything runs in your browser with a simple upload-and-slide workflow — no Photoshop, layers, or masking required. You can download a high-resolution result.
What photos work best for double exposure?
A subject with a clear silhouette (a portrait, profile, or well-separated object) plus a textured second image (a city, forest, mountains, or sky) produces the strongest results.
