3 Setting the Image-recording Quality
¡
The number of possible shots and maximum burst (p.54) apply to a Canon
512MB CF card.
¡
The single image size, number of possible shots, and maximum burst during
continuous shooting are based on Canon’s testing standards (ISO 100 with
[Parameter 1] set). The actual single image size, number of possible shots,
and maximum burst will vary depending on the subject, shooting mode, ISO
speed, parameters, etc.
¡
In the case of monochrome images (p.65), the file size will be smaller so the
number of possible shots will be higher.
¡
On the top LCD panel, you can check the remaining number of images the CF
card can record.
¡
A different image-recording quality can be set separately for the Basic Zone
modes and Creative Zone modes.
The RAW assumes that the image will undergo post-processing with a
personal computer. Special knowledge is required, but you can use the
bundled software to obtain the optimum effect.
Image processing refers to adjusting the RAW image’s white balance,
contrast, etc., to create the desired image.
Note that RAW images will not work with direct printing or DPOF.
