RAW image files are often described as digital negatives, because they are uncompressed, unprocessed files that accurately portray the data captured by the camera sensor. The RAW format is found in cameras, which are a little more advanced. It is meant for more advanced photographers as well requiring a little work with a computer to get the best out of the format. The problem is that all camera manufacturers support completely different RAW image formats. They keep the specifics of their formats proprietary and change the details between different camera models. We constantly update and test different cameras that support RAW image formats in addition to JPEG. If you possess one of Canon cameras that let you select storage in RAW format, such as Canon PowerShot S40, use ImageConverter Plus for further processing its files.
