1
1 is the raw image data before it is made into 73 or other images.
1 images cannot be viewed on a computer without the use of EOS
software, such as Digital Photo Professional (p.405). However, you can
perform various adjustments on them that are impossible with other
image types such as 73. 1 is effective when you want to precisely
adjust the image yourself or shoot an important subject.
1+73
1+73 records a 1 image and a 73 image with a single shot. The
two images are saved to the card simultaneously. The two images will be
saved in the same folder with the same file numbers (file extension .JPG for
JPEG and .CR2 for RAW). 73 images can be viewed or printed even with
a computer which does not have the EOS software installed.
