All digital cameras actually record the images in a JPEG format, that is, they have .jpg file extension and are compatible with computers and photediting software. But some top of the range more expensive cameras like Digital SLRs can also be set to take images in RAW format – which is often the preferred mode of professional photographers. A RAW file is comparable to the latent image contained in an exposed yet undeveloped piece of film. It can be called a digital negative and as unprocessed image lacks correct colours, contrast etc, but it can be fully manipulated and developed, and, by a professional, the final image will be superior to the JPEG. This is because the RAW images actually include more fine detail in bright and dark portions of the negative. The sun and clouds in a JPEG sunset photo are nowhere near what was seen by the naked eye, but the RAW image is capable of being processed to enhance this contrast. The real downside. Apart from the expertise needed to deal with RAW images is that the RAW files are pretty large. There are a number of RAW software packages such as
- C1 RAW workflow software
- Breeze Browser
- Bibble
- SilverFast DC pro
- Sharp Raw -
RAW files are for the specialist who may want to come back time and again to change and develop a special image as techniques and styles change.
Most people will use JPEG technology as the files are small and fit on a card, the images are more easily transmitted online and wirelessly and more photographers do not have the time or even the expertise to process their own files.
