What is the difference between blend modes?

Blend modes determine how two layers are mathematically combined. Multiply darkens by multiplying pixel values. Screen lightens by inverting and multiplying. Overlay combines Multiply and Screen based on whether pixels are lighter or darker than 50% grey.

Can I blend more than two images?

Yes. You can stack unlimited blend layers. Add as many images as you need, adjust each layer's position, size, rotation, opacity, and blend mode, then reorder them to control which appear on top.

Which blend mode should I use for a double exposure effect?

Screen blend mode is the classic choice for double exposure. It keeps bright areas visible from both images while dark areas become transparent, producing the characteristic ethereal look.

Do all images need to be the same size?

No. Each blend layer can be resized independently. You can adjust the width and height of each layer as a percentage of the base image, allowing you to blend images of any size.

Are my images uploaded to a server?
