RAW format is a record of the original digital camera CANON EOS Rebel xsi Charger sensor information, without processing also without compression file format, it is the biggest advantage of save the most original CCD data, for post-production left more space.
RAW in the strict sense, it is not the image format. RAW file is in the camera image data information storage all produced when, the image of shooting without doing any data processing, keep the picture of the original state. Any a digital SLR cameras can be shot and storage RAW files,Canon EOS Kiss digital Charger it relative to JPG format or TIFF format benefit is that any mistake could have exposure later in computer fixed, but also will not affect the quality of the picture itself. But, if the image has been locked in JPG format or TIFF format, that is impossible. A disadvantage of the RAW itself is its rely on on the computer in the treatment of time may be slightly longer, there is a serious problem, that is there is no unified standard can perform.
The RAW file save from camera photographic elements the original information, such as white balance, exposure correction, sharpening, contrast this kind of late adjustment, to a program or a RAW image editing program is better able to complete. Digital cameras in JPEG and TIFF conversion program can only a few parameters according to the established by digital camera Canon EOS Kiss digital Charger itself automatically convert work, and provides the RAW file more control options and adjust space, so the photographer can casually in one computer adjusted, more important is, JPEG is a lossy compression format, RAW and is nondestructive format.
RAW files can be seen as not after rinse of digital film negative, in flushing process of film and can be a little influence of control and optimized. But to us for the photographer, as technology update, Canon EOS Kiss digital x Charger digital RAW is also constantly updated, colour reduction, sharpening, such as noise reduction is in constant improvement law, its for the same RAW files of the treatment effect of more and more is also better.
Different RAW processing software processing ideas will be very big difference, this difference is not only Canon EOS Kiss F Charger reflected in the results come out, also reflected in different project specific adjustment options, batch mode, the user interface and guide to the process.
In RAW format with filming, except GanGuangDu outside of the parameters set meaning is not big. The proposal with the camera itself of the RAW format to shoot.
