Before starting taking pictures I would consider 3 points:
The result is tipically a blurred picture of backscattered particles of sand or silt generaged by poor buoyancy tipically of a tail of a fish all of this with bluish colors, to get that the dive had to be cut short to 35-40 minutes because of increased air consumption due to task loading
Ask yourself if you are going to be in that scenario, if yes first improve your diving and second read a book on how to take pictures and practice on land before even buying a housing, if you don't like self learning do a digital photography class and check the pictures of your instructor before booking.
Two divers can go on the same dive and take pictures of the same aquatic life with the same camera and the results can look completely different depending on the factors above
- Make sure you have good buoyancy control
- Ensure you have low air consumption
- have a good idea of what is a good subject and how to take a picture
