Besides the .raw suffix, there are many other Raw file formats. Raw files usually contain a vast amount of data that is uncompressed when shot on the digital camera or other photographic image capture device. As the name suggests, they’re raw because they’ve not been processed and therefore cannot be edited or printed until opened in an application such as Adobe Photoshop or Lightroom, Apple Aperture, Corel AfterShot Pro and Phase One Capture One Pro.
Capturing Raw files when shooting ensures you maintain greater control of your final images as Raw doesn’t just permit a greater scope for post-production due to the higher amount of data in the file, but also allows sharpness and image noise control that, if shooting in JPEG-only mode for example, may otherwise be compromised given the camera’s often limited internal processing capabilities.
Other Raw file formats include: .3fr, .ari, .arw, .bay, .crw, .cr2, .cap, .dcs, .dcr, .dng, .drf, .eip, .erf, .fff, .iiq, .k25, .kdc, .mdc, .mef, .mos, .mrw, .nef, .nrw, .obm, .orf, .pef, .ptx, .pxn, .r3d, .raf, .raw, .rwl, .rw2, .rwz, .sr2, .srf, .srw, .tif and .x3f
