RawConvert is an Automator Action for batch image conversion from Camera RAW to Photoshop or other formats. Works with most Digital Cameras that support RAW format. RAW format is the highest quality output from the camera, so by using RAW you can extract the best images, the downside is that RAW is large and requires processing into a usable format.
