About the Dust Delete Data
After the Dust Delete Data is obtained, it is appended to all the JPEG,
RAW, and sRAW images captured thereafter. Before an important
shoot, you should update the Dust Delete Data by obtaining it again.
For erasing dust spots automatically with the bundled software, see the
Software Instruction Manual in the CD-ROM.
The Dust Delete Data appended to the image is so small that it hardly
affects the image file size.
