Converting RAW Images

The RAW format records the image data as captured by the camera’s image sensor without further processing by the camera. Although the data is compressed when recorded, the original data can be completely restored without any loss of quality, making it possible to obtain high-quality images. Moreover, the RAW image file format is extremely compact, creating files that are approximately one-third to one-quarter the size of an uncompressed file (RGB TIFF). Please refer to your Camera User Guide to learn how to set the camera to shoot in the RAW format.

The process of obtaining high-quality RGB signals from RAW format images (hereafter RAW images) is called “conversion.” Since the Plug-In Module can be used to adjust the attributes of the original data, you can achieve the effects you wish while maintaining high image quality. In contrast, image data recorded in the RGB TIFF and other standard uncompressed file formats is irrevocably processed in the camera and must be further processed irrevocably by retouching software to change the attributes, which reduces the image quality.

Please note that ImageBrowser or the Plug-In Module are required to load RAW images onto a computer.

•ArcSoft PhotoImpression is not a Plug-In compliant program, and this function can not be used.
