SRW to FITS Conversion: FAQ

What are SRW files?

SRW is a proprietary format for RAW photos shot with some models of digital Samsung cameras. Shooting in RAW mode is usually preferred by professional photographers because it allows them to take advantage of all the info captured by the camera's sensor, and to edit the photograph in their desired way during post-processing. However, for amateurs or for photographers who are not familiar with using advanced image editing software, SRW files might prove difficult to handle. Converting to a more accessible format, such as JPEG, TIFF or PNG, provides easier access and smaller file size.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
