Build stability through buoyancy
A steady photograph begins with a controlled position in the water. Practice neutral buoyancy with your camera secured before approaching a subject. Keep your breathing calm and use small fin movements well away from the bottom, taking care not to stir sediment. If you are rising or sinking while composing, pause the attempt and regain a comfortable position. Trying to fix camera shake while your whole body is moving often leads to accidental contact or rushed movements.
Keep the camera close to your body
Hold the housing with both hands, keep elbows tucked in, and avoid extending your arms farther than necessary. This compact posture reduces the effect of small movements and helps prevent dangling gear from brushing habitat. Use the viewfinder or screen that lets you maintain awareness of your surroundings. If a camera strap, hose, or light is swinging, secure it before moving closer. Stability should come from your body position and careful handling rather than leaning on rock, kelp, or another structure.
Use a water-column posture
Depending on conditions and training, a diver may hover horizontally or adopt another stable posture that keeps fins and equipment above the bottom. Position yourself so you can see the subject without kicking toward it. In surge, allow the water to move you gently and wait for a calmer moment instead of fighting each motion. A wider composition can tolerate slight movement better than extreme close-up. If you cannot hold a safe distance, skip the image and return only if conditions and the subject allow.
Take the photograph without bracing
Press the shutter smoothly rather than jabbing at it, and use a short sequence if the camera supports it. Review the image for blur and check that your fins or lights have not disturbed the scene. If a frame is soft, adjust your posture or timing and try again from the same safe distance. Never use the seabed or a living organism as a camera rest. A slightly less sharp image made without contact is a better field record than a crisp frame that damages or dislodges the habitat.
