This camera records images as either JPEG images or RAW images.
JPEG image (
When pictures are taken as JPEG images, 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
original image data cannot be recovered once it has been compressed.
See Changing the Recording Pixels and Compression (Still Images)
(p. 78).
RAW image (
RAW data is the data output by the imaging element and converted to
digital data which is recorded as is.
This results in images with almost no deterioration in image quality and
a higher quality than JPEG images. To view RAW images on a
computer, you need to use the supplied software (ZoomBrowser EX/
ImageBrowser), which also lets you broadly adjust images without
deterioration in image quality. Using the software's image processing
functions, you can take the adjusted image data and convert it a JPEG,
TIFF or other type of image in line with your intended use.
You cannot use direct print or make print (DPOF) settings with images
taken with , however.
When downloading RAW images and simultaneously recorded
JPEG images on Windows XP, be sure to use the supplied
software.
