Underwater photography is much different than land photography. Light and color loss, water clarity, currents and housing condensation are all elements that affect underwater photography. The large Dive Certification organizations have complete classes dedicated to Digital Underwater photography. Digital cameras are complex and need to be understood and set properly to obtain best results.
SPOTS IN THE PICTURE: This is called backscatter and is usually caused by particles in the water reflecting back from the flash. This will happen with ANY camera that has a flash close to the lens. The flash goes out in a straight beam and particles in the water reflect the light back into the lens, causing spots. The best solution is an external strobe. With a strobe, the light reflects back to the strobe and away from the lens. It is not recommended to use the internal flash underwater. Another helpful item is a flash diffuser. The diffuser will help but will not eliminate backscatter.
