To combat against this, the EOS Rebel XSi features a Canon-designed Self Cleaning Sensor Unit. It’s not one feature, it’s a built-in system to minimize the effect of dust in high-resolution digital images.Ī key element of minimizing dust is preventing it from clinging to the front surface of the imaging sensor.

Canon Digital Photo Professional (DPP) version 3.3 or later software can be used to manually or automatically erase the dust spots. By shooting a plain white subject, the photographer can acquire dust position data that is transmitted along with the image (whether JPEG or RAW). Dust particles can also be automatically removed via software. (It can also be manually activated.) A special collar positioned around the sensor collects the loosened dust. This Self Cleaning Sensor Unit routine is automatically activated whenever the camera is powered on or off. Dust that settles on the sensor surface is removed using ultrasonic vibration. Photographers who must change lenses in dusty environments will find the advanced Canon EOS Integrated Cleaning System a tremendous time saver. All relevant shooting information, including ISO, is displayed right in the viewfinder so it’s easy to change settings without moving the camera away from the eye. And the EOS Rebel XSi has a Display-Off sensor that automatically turns the LCD monitor off whenever the camera is at the photographer’s eye. The EOS Rebel XSi also has an improved, high magnification viewfinder that provides a larger overall view, and increased brightness and clarity. It also provides Center-weighted average metering and partial metering for accurate exposure no matter the situation. It now features a spot meter, which reads a tiny area (about 4%) of the picture for extremely precise metering. The EOS Rebel XSi’s 35-zone evaluative metering system with improved white balance analyzes light based on each zone in the viewing area, enabling the camera to choose the overall best exposure for the entire scene. Digital noise is significantly reduced in shadow areas, and color reproduction is superior. The entire electronic system is totally redesigned, giving the camera its incredible combination of speed and image quality. It’s now available in all shooting modes, including P, Tv, Av, and Manual.ĭeveloped to maximize performance between the capture and recording stages of digital photography, the EOS Rebel XSi’s latest-generation DIGIC III Image Processor works in concert with Canon’s CMOS sensor to achieve even higher levels of performance.
It can actually lighten dark areas of a scene while ensuring that bright areas maintain tonal detail. The EOS Rebel XSi’s Auto Optimization is yet another image-quality tool that comes to the rescue in tricky lighting conditions. Another huge benefit of the 14-bit conversion is the Highlight Tone Priority option, which allows critical shooters to increase the level of detail in bright areas of a scene up to one stop, without affecting overall exposure.

Even JPEG files, which are always finished at 8-bits per channel, use the full 14-bit conversion initially to generate the best possible color and tonal detail. With this rich 14-bit gradation the EOS Rebel XSi offers RAW images of the highest quality that can be processed with Canon’s Digital Photo Professional software.

Formerly a feature only present in top-of-the-line pro digital SLR cameras, the 14-bit conversion gives incredibly smooth transitions from light to dark colors, with far less risk of 'banding.' A sky at sunset is a perfect example. With the EOS Rebel XSi, analog to digital signal conversion is executed by a 14-bit processor, which generates digital data with incredibly smooth tones. It works in concert with the EOS Rebel XSi’s sensor to achieve unprecedented levels of performance in all lighting situations. Canon’s DIGIC III Image Processor dramatically enhances image quality and speeds up all camera operations for intuitive operation.
It’s an APS-C size sensor (22.2 x 14.8mm), and there’s an effective 1.6x increase in the lens’s marked focal length when attached. It offers many of the same new technologies to maximize each pixel’s light gathering efficiency that were first seen with the professional EOS-1D Mark III model. Canon’s CMOS (complementary metal oxide semiconductor) sensor captures images with exceptional clarity and tonal range, and offers the most pixels in its class.
