Memory Card

After the digital image sensor has captured the image, the camera employs a series of processes to optimize the image. Many of these processes are based on camera settings established by the photographer prior to taking the shot, such as the ISO setting. After image processing, the camera stores the digital information in a file.
The type of digital file created varies depending on the camera’s manufacturer. However, the camera’s RAW file contains the digital image data before it has been converted to a standardized file type, such as JPEG or TIFF. Not all RAW files are alike, but the image data produced by your camera’s digital image sensor and processor is retained bit for bit in that file.  Once the file is ready for storage, the camera transfers the file from its processor to the memory card. There are several types of memory cards, but the process by which they receive the information is the same.
