I am forever fasci-
nated by how Nature repeats
herself. Like all living creatures,
flowers have their very
distinct personalities and
similar to making a portrait
of a person, when photo-
graphing flowers I am chal-
lenged to capture something
of their individual personali-
ties, moods and gestures. "

Canon's Amazing CMOS Sensor
Massive Files, Better
Detail
Canon's new 10.1-million
pixel CMOS sensor uses technology straight
from the professional EOS-1D Mark III. It's
totally re-designed, reaching new levels of light-
gathering efficiency and low-noise performance.
The APS-C size sensor has the same effective
lens conversion factor (1.6x) as the previous
EOS 30D. In conjunction with the new DIGIC III
Image Processor and this new CMOS sensor,
the EOS 40D images break new ground in total
image quality.
14-bit Depth for Greater Color Range
With the EOS 40D, analog to digital signal conver-
sion is executed by a 14-bit processor (16,384
tones), which generates digital data of fine
gradation without tonal skipping. Canon's pro-
prietary RAW and new small RAW (sRAW) images
take full advantage of this rich 14-bit gradation
and can be processed with Canon's Digital Photo
Professional software. JPEG images with 8 bits
per color derived from 14-bit data are provided
in four sizes (10.1MP, 8.0MP, 5.3MP or 2.5MP),

which also are available in the EOS 40D's RAW +
JPEG mode.
