Quelle vitesse de carte pour la photo RAW sous-marine ?

Minimum V60 (60 Mo/s). Pour haute resolution ou rafale : CFexpress (400+ Mo/s). Video 4K : V30 minimum.

Combien de cartes pour un voyage plongee ?

Minimum 2 cartes par jour. En RAW 24 MP : environ 200 photos par 32 Go. Pour 10 jours : 128 Go minimum sur plusieurs cartes.

La chaleur affecte-t-elle les cartes en plongee ?

L'eau refroidit naturellement le caisson. Le risque est en surface, sous le soleil. Ne pas laisser le caisson au soleil entre les plongees.

Data Flow and Storage: Memory Cards for Underwater Photography

The Buffer: The Data Waiting Room

The sensor produces data faster than the card can write it. The buffer temporarily stores this data. Its size determines how many burst shots you can take before the device slows down.

Full buffer = device freezes. The larger the buffer and the faster the card, the more shots you can take without interruption. Crucial for capturing a school of fish or fleeting animal behavior.
