Plan a decompression dive by matching your training, gas supply, team procedures, exposure protection, and contingencies to a conservative written dive plan. Advanced certification alone does not qualify a diver for planned decompression diving, so use formal decompression training and local guidance.
For underwater photography without a red filter, shoot RAW and use a custom white balance at subject depth whenever your camera allows it. A Kelvin setting is a useful fallback, but it needs adjustment for depth, water color, distance, and whether you use strobes.
How to shoot macro photography underwater starts with stable buoyancy, a patient approach, close focus, and controlled light. These practical settings and field habits help you photograph small critters without stressing them or damaging the reef.
To reduce camera shake underwater, stabilize your buoyancy first, keep the camera close to your body, use slower and more deliberate movements, and match camera settings to the available light. Small changes to trim, grip, finning, and shot planning can make underwater video look far smoother.
Learn how to photograph divers underwater with practical posing, composition, lighting, and camera-setting advice. These tips help you direct a buddy, reduce clutter, and get stronger images without disrupting the dive.
Use a clean bathtub, oral inflation, and a slow bubble check to find common BCD bladder, dump-valve, and inflator leaks at home. A bathtub test can identify a problem, but a leaking BCD needs inspection by an authorized technician before diving.
Most fast dive computer battery loss comes from an activated wet contact, Bluetooth connection, backlight setting, or a battery compartment problem rather than age alone. Use this troubleshooting sequence to find the drain, protect the seal, and know when professional service is the safer choice.
A regulator free flow usually comes from water, debris, an incorrect control setting, cold conditions, or a first-stage pressure problem. Learn what to do underwater, what you can safely check on land, and when the regulator needs professional service.
A small clean tear in neoprene can often be repaired at home with neoprene glue if the edges still meet cleanly. Careful cleaning, dry fitting, thin glue coats, and full curing matter more than using lots of adhesive.
Rinse the zipper with fresh water, remove trapped grit with a soft brush, then apply a zipper-specific lubricant only after it is clean and dry. Do not force a BCD zipper, especially if it is part of the bladder cover or an integrated-weight system.
