DPOF

Digital Print Order Format is a standard format for ordering prints of digital camera images from photo lab printing services, as well as printing from household printers. The Canon EOS D30 is DPOF-compatible. You can specify printing from the camera itself and store the order information on the CF card. Photo printing services or household printers using the DPOF format can then produce prints easily using that information.

Exposure

Exposure refers to the amount of light striking the imaging element to produce a photograph. The amount of light appropriate for the ISO speed is called the correct exposure. The correct exposure is adjusted by changing the combination of the shutter speed and aperture value.

File Numbering and Folders

The pictures you take are automatically assigned file numbers from 0001-9900 and stored in folders of 100 images each. Each folder is numbered from 100 to 998 and recorded on the CF card. Because pictures taken using continuous shooting must

be stored in the same folder, there may in some cases be							~
				100	0001	0002	0099	0100
more than 101 images in a folder. Folders with 99 as their
last two digits are not created.							~
Images stored in formats other than RAW format have the				101	0101	0102	0199	0200
				•
file name Img_ and the extension ‘jpg’, and images stored				•
				•
in RAW format have the file name CRW_ and the extension							~
‘crw’. Images with the extension ‘thm’ are thumbnail
				198	9801	9802	9899	9900
images for index display.							~
