When photographing underwater, there are three shooting techniques you will find particularly useful as they enable you to produce remarkable and appealing pictures without elaborate set-ups.
For small underwater subjects, choose the Macro Mode. Move to within minimum focusing distance of your subject and depress the shutter button halfway. Then using the LCD monitor, move the camera to sharpen your image. Finally, press the shutter button all the way to take the picture. Utilize the flash diffusion plate on the case to ensure even underwater flash lighting.
The first thing to master with wide-angle shots is keeping the water color blue. To keep water looking blue, first set the White Balance*: choose "Daylight" in shallow water and "Cloudy" for greater depths. Then, get below your subject. Aim upward towards the sky to create dramatic silhouettes. *If your PowerShot digital camera has Underwater Scene Mode, select it for the best results when shooting underwater.
First, select the Stitch Assist Mode on your PowerShot digital camera. Shoot a series of overlapping images. Then use the PhotoStitch Software, supplied with your camera, to automatically combine images into a breath-taking panorama on your computer.
You can also use your Canon Waterproof Case on land ? in environments where snow, sand, excess humidity or dust could lead to damage. Ideal for skiing and many other activities, a Canon Waterproof or All-weather Case provide an added measure of safety for your PowerShot camera on land.
