The RAW format preserves more of the original information from the camera than the JPEG files. Many photographers shoot in RAW mode which outputs a file format that is proprietary to their camera models, that's why special universal RAW image processing software is required. ImageConverter Plus has worked with the major camera manufacturers to view, convert and edit RAW files. If high image quality is your priority, choose the RAW format of Canon PowerShot G9 and maximize the potential of your images.
