What is File formats?

TIFF (Tagged Image File Format)


TIF, as it is mostly referred to, is the industry standard for digital images. TIF files can be compressed or uncompressed and come in a PC and a Mac version, both of which can be accessed on either platform. You can view and manipulate TIF files on all computer platforms and in almost any image editing software.


RAW

  • RAW files come in many shapes and forms, but they all have some things in common:

  • · G A RAW file is the ‘raw’ untouched file which comes straight from the camera’s CCD or CMOS sensor.

  • · G RAW files can be compressed or uncompressed.

  • · G Each camera manufacturer has its own version of the RAW format. Canon digital cameras produce CRF (Canon Raw Files), Nikon cameras produce NEF (Nikon Electronic Files) and Adobe has been trying to establish an industry standard called DNG (Digital Negative).

  • · G Headroom is the dynamic range that you can push in post-production either to show more details in the high-lights or shadows.

  • · G With a RAW file you can adjust your white balance and other properties in post production, which can otherwise be extremely difficult with TIF and JPEGs unless you use the newer version of, for instance, Photoshop.

  • · G The RAW image file also contains metadata about the photograph, such as the camera used, lens, exposure, aperture and sometimes location data if the camera has GPS built-in. This information can be useful for cataloguing purposes and online presentations.


Image software such as Adobe Photoshop and Adobe Photoshop Elements is shipped with a plug-in called Camera Raw that can open almost all RAW file formats. RAW files are about 1/3 smaller than TIF files and you can therefore store more images on your card with RAW than with TIF.
