• JPEG images / / / / /
When JPEG images are recorded, the images are processed inside the camera
for optimum image quality, and also compressed to allow a larger number of
images to be stored on the memory card. However, the compression process is
irreversible, meaning that the raw data cannot be recovered once it has been
compressed. Moreover, the image processing results in a deterioration in
quality.
• RAW images
A RAW image is raw data recorded with nearly no deterioration in image quality
resulting from image processing inside the camera. This data cannot be used as
is for viewing or printing on a computer. The supplied software (Digital Photo
Professional) must first be used to convert the image data to a JPEG or TIFF
file. When converting the image data, you can adjust the image with minimal
deterioration in image quality.
Simultaneously Recording RAW and JPEG
Images
Two images, a RAW image and a JPEG image will be recorded with each
shot.
Since a JPEG image is also recorded, you can print the image or view it on a
computer without using the supplied software.
The file extension for RAW images is “.CR2”, and the extension for JPEG
images is “.JPG”. The JPEG images will be recorded with
recording
pixels with image compression.
