The EOS 20D camera has professional level white balance controls. In addition to Auto, it has six presets, a Custom setting and direct specification of color temperature. White balance can be corrected for blue, amber, magenta or green; white balance bracketing, up to +/- 3 whole stops, can be performed for magenta-green as well as blue-amber.

Flash Forward: Canon Speedlite 580EX

When the EOS 20D digital camera is used with the built-in flash or the new Speedlite 580EX, color temperature data transmission is enabled. The camera has an extensive complement of white balance controls, processing parameters, bracketing options, shooting modes and custom functions that permit the camera to be configured for any situation; the revised menu format, simplified control layout and clever new Multi-controller make the camera easy to use.

Evolved E-TTL II Flash Exposure Control

Though still compatible with all EX-series Speedlites, the “smarter” E-TTL II system captures the subject as a “plane” and ensures that images containing various colors and levels of reflection are captured accurately and optimally. The system compares the ambient light with the reflected pre-flash off the subject reported in all 35 metering zones and selects the areas with a small difference to be weighted for flash exposure calculation. This system also eliminates or under weights areas with large difference recognizing them as an extremely reflective object in the background or as a highly reflective subject, smartly ensuring it by considering the distance information data provided from compatible EF lenses. The system similarly prevents over-exposure when photographers lock focus and recompose the shot by considering the flash output level calculated according to the broader distance. The camera also allows users to select an average metering pattern by using its custom function settings.

New CMOS Image Sensor and DIGIC II Image Processor

The EOS 20D digital SLR includes Canon’s latest CMOS image sensor technology as well as the new DIGIC II Image Processor. The CMOS features high-speed 4-channel data reading, brilliant new microlens technology, a 2nd generation, on-chip noise-reduction circuit, and low-noise, high-speed amp, which produces accurate color, extremely low noise and fast recording even at ISO’s of 400 and above. Canon’s DIGIC II image processor is without question, the most powerful imaging processor that the company has ever put into a digital camera. It boasts improved color reproduction of high-saturation, bright subjects, improved auto white balance precision, and wider dynamic range in highlight areas. In addition to its image quality improvements, the DIGIC II chip is also responsible for speeding up camera performance in areas such as start-up time, autofocus calculation, card-writing speed, direct printing and data transfer speed through the new USB 2.0 High Speed interface.
