Experience Digital Underwater Cameras Good photography basics are different for underwater pictures than they are for typical landbased photography. Lighting, color contrast, and closeness to subject are all affected by underwater conditions. Using digital underwater cameras effectively requires some basic strategies and forethought, as, well as, different equipment.Underwater cameras are all designated as water-proof and are necessary for snorkeling or deep-water diving. They are also useful in kayaking, rafting, and rainy conditions, when components could be exposed to more than a little water. Expected conditions will determine whether the need is for a rugged waterproof housing to protect the camera or a specially designed underwater camera is necessary. Best Waterproof Cameras The GoPro HD Naked Hero Camera captures high performance 1080p video as well as 5megapixel still images. You can also set the video resolution to 960p or 720p at 30 or 60 frames per second. On a full charge, you can record up to 2.5 hours.The camera can also be set to automatically shoot still photos every 2, 5, 10, 30 or 60 seconds during your activity.With the HD Hero's higher resolution and improved low-light sensitivity, video quality is higher. A spot metering setting improves exposure levels when recording videos from inside a vehicle. Normally, exposure levels are problematic because of the differences in the lighting level outside of the vehicle and the light in the cabin.At any rate, best results are achieved when capturing images in daylight. Indoor photography is rather poor, with the color taking on a yellowish cast. This has something to do with the camera's white balance.
