Today’s digital photography equivalent of a film negative is the RAW format image file. RAW images are the most accurate photo record that your camera can produce. Because RAW files can’t be modified, they are a kin to a negative and must be processed to use them effectively (please read articles for a description of some common image file types). JPEG format files should not be used in the field for photo-ID photos. The JPEG format does not capture the reality of the image nearly as well as the RAW format. It does not contain detail that can be edited if the lighting is poor or the animal is distant, and JPEG compression algorithms can tend to add digital artifacts (erroneous markings) that show when the image has been enlarged.Recent advances in photo editing tools allow us to work directly (and efficiently) with RAW files rather than having to pre-process RAW files using the digital camera’s software tools. Photo editing tools now allow users to view, edit and “Batch Convert File Format” to convert RAW files (7-15 Mbytes on average) to “best compressed” JPEG files (about 300-600 Kbytes on average). These compressed JPEG files show an amazing amount of detail even when enlarged over 200%. And if the quality of the compressed JPEG is not sufficient, the RAW file can be edited and re-converted to compressed JPEG.
Here are some guidelines to follow when using digital photography for photo-identification studies:
-Always shoot at the highest resolution of the camera, e.g., RAW. Use fast flash cards (>80x writespeed).
-Think of RAW as your original negative and archive the RAW files the same way you’d archive your negatives
-Convert the RAW images to compressed JPEG to use as your working images. If you need to edityour compressed JPEG image, go back and edit the RAW file and then save a new, edited compressed JPEG file.

Do you need information about Car Company or dealer cost car? Here is about general motors. General Motors was founded on 16 September 1908 by William C. Durant. It is founded and acquired in the same year the company’s Buick and Oldsmobile. During the 1920s and 1930s took on General Motors, the company Yellow Coach, helped create Greyhound bus lines long, and replaced interurban streetcars by buses. GM formed subsidiaries to other companies, the trams manufactured to buy and replace the paths used by buses. 1930 GM bought the car engine manufacturer Winton engine and put the production of electric to diesel engines. With the Flint strike began at the turn of 1936/37, the large-scale unionization of workers at GM. During the Second World War, it was supplying General Motors and its affiliates both warring parties. This alone comprised one-tenth of total U.S. war production. The company serves both the U.S. Army and the armed forces of the German Empire with trucks.
After the Second World War, General Motors and Ford claimed reparations from the U.S. Government, as its factories had been damaged in Germany by the Allied attacks. In public, the belief is widespread that General Motors was convicted in the 1950s because of a conspiracy. Have been object of the conspiracy intended to buy up the network of electric trams and destroy, so that public transport on GMC buses had been instructed. This should be the reason why trams today rarely found in the USA. This conspiracy theory contradicts that General Motors was convicted only for the pressure applied to the acquired bus companies to use these buses from GM should.
On 31 General Motors announced in December 1955 as the first American company has an annual sale of over one billion U.S. dollars. GM posted 1981 sales of about 60 billion U.S. dollars and employed 657 000 employees. In 2003, GM reached a turnover of 185.52 billion U.S. dollars, 51.63 billion abroad. Worldwide, 294 000 employees, of which employs 104 000 outside the U.S.. After Kirk Kerkorian, who had failed so far the largest single shareholder, favored alliance with Renault / Nissan 2006, this sold most of its shares.
