## What is UnderBlue?

UnderBlue brings believable colour and clarity back to underwater photos and videos.

Choose a photo or video, pick a look, and compare it with the original. Adjust the look's intensity, or use Custom to set brightness, contrast, saturation, clarity and temperature yourself. Behind the scenes, UnderBlue uses depth-aware underwater restoration to reduce colour loss and backscatter while keeping the result natural and temporally stable.

Features:

• Natural Dive, Tropical and Deep Dive looks
• Custom look with five adjustment sliders
• Depth-aware photo and video restoration
• Temporally stabilized video correction
• Original-resolution and 4K video export with UnderBlue Pro

• HDR photo export with a gain map, with UnderBlue Pro
• Import from Photos, from Files (camera RAW included) or from the share sheet
• Original frame rate, timing, orientation and audio preservation
• Fully on-device processing with no account or cloud upload

Try one photo export and the first 10 seconds of one video for free. UnderBlue Pro is a one-time purchase that unlocks unlimited photos (up to 10 at a time), full-length video, 4K and supported HDR export.

### 5/5 — What an app

*2026-10-20*

Wow i didn’t expect my underwater pictures have such a potential. After filter applied, it turns the raw photos into the real amazing scene that i captured with my eyes. It’s amazing

### 5/5 — Amazing

*2026-10-19*

This site is great. After you go through all the trouble of diving and trying to capture exactly what you see under the water, it’s often disappointing when your pics come back lacking that same clarity or color that you saw under the water.  Light refractions and glare can interfere with the actual photos. But this app really makes your photos come alive. All the detail and colors you see under the water can be rendered in this app. Perfect when showing off your dive trips!  Highly recommend it.
