The world of underwater macro is a universe of its own. It’s a realm of tiny, intricate creatures with otherworldly patterns and behaviors. Capturing this hidden beauty is one of the most rewarding challenges in underwater photography. While modern smartphones possess incredibly powerful cameras, accessing their advanced features for macro work underwater has been the biggest hurdle—until now.
The DIVEVOLK full touchscreen housing is the key that unlocks the "secret weapons" in your phone's camera app, giving you a level of creative control that rivals dedicated camera systems. Let's dive into five specific techniques that are now at your fingertips.
1. Pinpoint Focus Selection (Beyond Auto-Focus)
The Challenge: Action cameras and button-only phone housings are often stuck with system auto-focus. The camera tries its best, but it frequently focuses on the colorful coral behind your tiny subject instead of the nudibranch's delicate rhinophores or the eye of a shrimp.
The Touchscreen Solution: With a DIVEVOLK housing, you have complete artistic control. Just like on land, you simply tap the screen to select your precise focus point. This tells your phone exactly what matters in the frame, ensuring your tiny subject is perfectly sharp while the background falls into a pleasing blur. This single feature is a game-changer for creative composition.

2. Taming the Light with One-Tap Exposure Metering
The Challenge: You've got your video light perfectly aimed at a bright yellow goby. You take the shot, but the goby is completely white and washed out—a classic case of "blown-out highlights" or overexposure.
The Touchscreen Solution: When you tap to focus on your subject, your phone's camera app does something brilliant: it also automatically meters the exposure for that specific point. It instantly recognizes that your subject is bright and adjusts the overall image brightness accordingly. This simple tap prevents overexposure on your subject, giving you a perfectly balanced image with rich detail and color, even with a strong light source.
3. Crafting Dramatic Black Backgrounds with EV Control
This is a pro-level technique that the DIVEVOLK touchscreen makes surprisingly simple. A dramatic black background makes your macro subject pop and is a hallmark of award-winning images.
The Touchscreen Solution:
- Tap and hold on your subject to lock both focus and exposure (you'll often see an "AE/AF LOCK" notification on screen).
- A small "sun" icon will appear next to the focus box. This is your Exposure Value (EV) or exposure compensation slider.
- Now, simply drag your finger down on the screen. You will see the background instantly darken as you lower the EV.
When you combine this technique with a focused video light on your subject, you get that stunning, professional "black background" macro effect. The background disappears, and all attention is on your beautifully lit subject.

4. Freezing the Perfect Moment with Burst Mode
The Challenge: Your subject—a tiny cleaner shrimp or a darting goby—is constantly moving. Trying to time a single shot to capture the perfect pose is nearly impossible.
The Touchscreen Solution: Use your iPhone's Burst Mode. With the DIVEVOLK housing, you can easily activate it with a quick press and downward (or leftward, depending on orientation) slide of the on-screen shutter button. This captures dozens of photos in a split second. Later, you can go into your photo album, tap "Select..." on the burst series, and easily pick the one or two perfect frames where your subject has the ideal pose, sharp focus, and best angle. It dramatically increases your chances of nailing that "money shot."

5. The Perfect Macro Toolkit: The Right Light & Snoot
Great technique deserves great gear. For macro photography, a small, focused light is often far more effective than a large, wide one. A compact video light like our SL-20 is powerful enough to illuminate your subject without flooding the whole scene with light.
For the ultimate creative control, you can add a snoot to your light. A snoot narrows the light beam into a tight, controllable spotlight, which is the ultimate tool for creating those dramatic black backgrounds. For this reason, we've curated what we believe is the most effective and user-friendly macro kit for smartphone divers.
