My Colors lets you change the tone of an image, for example to sepia or black & white, when shooting:
Vivid Emphasises the contrast and colour saturation for a vivid effect
Neutral Tones down the contrast and colour saturation for neutral hues
Sepia Changes the image to sepia tones
B/W Changes the image to black & white
Custom Color You can adjust contrast, sharpness, and colour saturation etc. to your preference.
Handheld Night Scene
This is a special shooting mode on many new PowerShot and IXUS cameras that allows you to take photographs at night without the need for a tripod. Your camera takes a high-speed sequence of shots and combines these in the camera into a single image to reduce camera shake and noise.
