Zoner Photo Studio includes a professional module for processing RAW files. These files, obtainable from many cameras, contain unprocessed ("raw") values directly from the camera sensor. To obtain a picture from these values, the data must first be converted ("developed") into a standard picture format like JPEG or TIFF. The RAW module lets you edit numerous settings like lightness, white balance, and sharpness before developing a picture.
The RAW module offers several groups of settings to help optimize the how the RAW is converted. These groups are Exposure, White Balance, Sharpness, Tone Curve, Color, Noise Reduction, Rotation, HDR, Color Correction, and Grayscale. A histogram can be shown in the module, and a history list for settings changes is available, so you can compare what effects individual edits will have.
The RAW module also lets you put pictures into a processing queue. This is especially useful with large picture batches, since it prevents long waits during that long process. You can give each picture (or several selected pictures) its own conversion settings and then add it to the queue. The whole queue is processed at once, and processing can be paused and continued at any time.
Zoner Photo Studio normally uses what are called WIC codecs to decode RAW files. In some situations it uses an external program named dcraw, which enables loading of previews and EXIF information from the following RAW formats:
|ARW/SR2/SRF||Sony RAW Image|
|CRW/CR2||Canon RAW Image|
|DNG||Adobe Digital Negative ("Adobe RAW")|
|ERF||Epson RAW Image|
|KDC||Kodak Digital Camera Image|
|MEF||Mamiya RAW Image|
|MRW||Minolta RAW Image|
|NEF/NRW||Nikon RAW Image|
|ORF||Olympus RAW Image|
|PEF||Pentax RAW Image|
|RAF||Fuji Camera RAW Image|
|RAW/RW2||Panasonic RAW Image|
|RWZ||Rawzor Compressed RAW|
|X3F||Sigma RAW Image|
|3FR/FFF||Hasselblad RAW Image|
Adobe, Inc. has made a commendable effort to standardize the chaotic world of RAW formats, with its creation of the universal DNG format. And Zoner Photo Studio uses DNG to obtain pictures from the RAW formats it supports directly. But nearly any RAW format—not just these few—can be converted to DNG. The Adobe DNG Converter, accepts over 200 RAW formats… and Zoner Photo Studio cooperates seamlessly with Adobe DNG Converter.
