These files are sometimes also called digital negatives, because they serve same purpose as negatives  in film photography.

There are many different RAW formats, most of them based on TIFF format. Major digital camera manufacturers assign different extension for their RAW formats. One of the most known RAW formats include:

  • KDC (Kodak)
  • CR2 (Canon)
  • ERF (Epson)
  • NEF (Nikon)
  • ORF (Olympus)
  • RW2 (Panasonic)
  • SR2 (Sony)

CD/DVD image file

Usually binary image of CD, DVD disc. Some CD/DVD burning applications not support CD/DVD images with .RAW file extension, but sometimes can help rename the .RAW to the .ISO. Be careful and be sure, that the .RAW file is the CD/DVD image. Often is the .RAW file a picture file in the RAW format or sound in the RAW format.

HP V41 program files

The RAW file extension is associated with HP V41.

From its introduction in 1979 until final production in 1990, the Hewlett Packard 41 Series Programmable Calculator reigned supreme as the trusted companion of professionals and students worldwide.

Its instant success was due to innovation, quality and a well established base of loyal customers. The HP-41 became the object of fascination to a vast following of dedicated enthusiasts which sprang up to explore its intricacies and possibilities.

Even today, its classic design makes it a useful and collectable tool with yet a few surprises left. This site is dedicated to documenting and preserving this amazing machine.


ISIS RAW file format files

The RAW file extension is associated with the ISIS. ISIS pulsed neutron and muon source at the Rutherford Appleton Laboratory in Oxfordshire. Data collected during an experiment on an ISIS instrument is saved to disk as an ISIS RAW data file.

Nicolet Summit DaStar data files

Nicolet is a worldwide leader in high performance data acquisition systems, transient recorders and digital oscilloscopes for the physical, mechanical and electrical marketplaces.

Typical product specifications feature high digital resolution, deep sample memory, synchronous sampling, and complete “sensor to report” integrated systems.

A wide range of software supports data analysis, automated operation, and remote control over a PC network. Recently, Nicolet introduced a new line of high performance dynamics analyzers for spectral measurements.


Nimbus 7 data file

The Department of Atmospheric Physics has accumulated a valuable archive of atmospheric infra-red radiance measurements from its satellite experiments which started with the Nimbus 4 SCR in 1970.

Originally data was recorded on magnetic tape. The old tapes became unreliable and data was copied to optical discs in 1990.

The optical disc media in turn became expensive and unreliable to support. In 1997 a NERC SEEDCORN grant was awarded to move the data to CD-ROMs which could make the data available on a wide variety of hardware. This opportunity was also used to catalogue and publicise the archive.

This archive is intended as a supplement to that at the British Atmospheric Data Centre which concentrates on retrieved geophysical parameters (Temperatures, volume mixing ratios etc) rather than the radiance data available here.

Low level radiance data is less in demand not least because its interpretation requires more knowledge of the details of the instrument making the measurements.
