Think about fin wash
Fin contact is obvious, but fin wash is the quieter problem. It can bury a subject, stir silt or damage delicate life even when you never touch the bottom.

Finning Skills for Macro Divers
Calmer propulsion, less silt and better control around fragile subjects.
Good photos start with good propulsion
Finning is easy to ignore because it feels basic, but for macro divers it is one of the biggest factors in environmental impact and image quality.
Many small subjects live on soft sediment, rubble slopes, hydroids, algae and other habitats that can be damaged or buried by careless fin wash. Good finning protects the seabed, keeps the water clear, improves your control and helps you leave the subject as you found it.
Key points
Simple propulsion habits that reduce impact and improve control around tiny subjects.
Keep trim first
If your feet are low, your kick will hit the bottom. Good trim makes almost every finning problem easier to fix.
Approach and leave with the same care
Many divers approach carefully, then disturb the subject while turning away. When you finish the shot, check where your fins and wake will go next.
Practise away from the subject
Do not use live critters as your training ground. Practise hovering, turning and controlled kick styles in clear water first.

Frequently asked questions
Why are finning skills important in macro diving?
Macro diving often happens close to sand, rubble and small animals. Better finning reduces silt, protects the habitat and helps you hold position without crashing into the bottom.
What kick is best over silty bottoms?
A frog kick or a small modified flutter is often better than big bicycle-style kicks because it sends less wash downwards.
Should I stop finning when I take a photo?
Usually yes. It is normally better to stop, hover and settle before taking the shot rather than finning while you frame the image.
Why do divers damage the bottom when leaving a subject?
Many divers focus on the subject while approaching, then forget their fins and the sediment behind them when turning away. Leaving carefully is just as important as approaching carefully.
Do I need to learn technical finning skills for macro diving?
Not necessarily, but practising calm propulsion, controlled turns and good trim can make a big difference. Formal coaching can help if you want to improve faster.
Should divers use their hands to steady themselves?
No. Grabbing the bottom, reef or marine life should be avoided. Better buoyancy and finning are the safer and more responsible answer.
