RAW Images and JPEG Images
z RAW images are raw data from the image sensor that are recorded to
the card digitally as
1
or D (smaller than
1
) files, depending on
your selection.
You can use Digital Photo Professional (EOS software) to process RAW
images. You can make various adjustments to images depending upon
how they will be used and can generate JPEG or other types of images
reflecting the effects of those adjustments.
z If [–] is set for both the RAW image and JPEG image,
73
will be set.
z If you select both RAW and JPEG, each time you shoot, the image
will be recorded simultaneously to the card in both RAW and JPEG
at the image-recording qualities that were set. The two images will be
recorded with the same file numbers (1). The file extension (2) is .JPG
for JPEG and .CR3 for RAW.
