Superimpose for iPhone

App snapshot

Superimpose is a mobile image editor that merges two photographs by placing one image subtly behind another. It gives you a range of blend options and editing controls so you can control how the two pictures interact. The app is feature-rich but typically works best when used with a deliberate, step-by-step approach.

How the merging works

• Use masking and selection tools to isolate the foreground or background elements before combining.
• Pick from several blending styles and adjust opacity to get the desired visual mix.
• Export your final composite directly from the device once you’ve tweaked colors and edges.
• Access layer controls and refinement tools to polish transitions between the two images.

Practical workflow tips

Start with high-contrast subjects and clear edges for easier masking. Work non-destructively when possible (save intermediate copies) so you can revert if a blend or mask doesn’t look right. Take advantage of zoom and soft brushes to smooth seams where the two images meet. Because the app offers many options, following a consistent routine will save time and produce cleaner composites.

Free options and alternatives

• Snapseed — a free, straightforward editor that handles many touch-ups and quick composites.
• GarageBand (Free) — listed as a top free alternative; note that it’s primarily an audio production app, so it’s only relevant if you’re assembling multimedia projects that combine sound with imagery.
