Macro Shots: 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

Wide angle Shots: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
.
Panorama Shots: 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 breathtaking panorama on your computer.
