Hello Crazy_Cuttlefish,
Both Intova Air Lens and Intova Wide Angle Lens allow for wide angle photography underwater, thus image magnification is reduced (0.75X and 0.65X respectively). This is good for panoramic shots or in tight spaces where you want to get more of the scene area. For getting closer to your subject, use IC12's zoom feature if your subject is camera shy or macro focus capability if you can get physically close to your subject. Getting a strobe (like our Intova ISS4000) will improve color and brightness of your photography especially in lower light conditions. A red filter is another alternative that will improve color at depths below 20 ft in bright ambient light conditions. Don't use a strobe and red filter together, your pics will be too warm in color.
Best Regards,
Intova
