The Promise of Perfect Images

EOS Integrated Cleaning System
Photographers who must change lenses in dusty environments will find the advanced Canon EOS Integrated Cleaning System a tremendous time saver. Dust that settles on the sensor surface is removed using ultrasonic vibration. This Self Cleaning Sensor Unit routine is automatically activated whenever the camera is powered on or off. (It can also be manually activated.) A special collar positioned around the sensor collects the loosened dust. Dust particles can also be automatically removed via software. By shooting a plain white subject, the photographer can acquire dust position data that is transmitted along with the image (whether JPEG or RAW). Canon Digital Photo Professional (DPP) version 3.1 or higher software can then be used to manually or automatically erase the dust spots. It's not one feature, it's a built-in system to minimize the effect of dust in high-resolution digital images.


Self Cleaning Sensor Unit
A key element of minimizing dust is preventing it from clinging to the front surface of the imaging sensor. To combat against this, the EOS 40D features a Canon-designed Self Cleaning Sensor Unit. The low-pass filter at the front of the sensor shakes off dust automatically with ultrasonic vibrations, removing dust from the sensor assembly.

Dust Delete Data Detection
Dust that may still remain on the front of the sensor can also be erased with software included in Digital Photo Professional (DPP) Version 3.1 or higher. A simple test shot of a plain, white object can be taken, using a menu setting. This Dust Delete Data image is analyzed in-camera, and the location and size of any remaining dust is added to any subsequent pictures taken. This data is transmitted along with the image, whether JPEG or RAW, and can be either manually or automatically erased in Canon's DPP version 3.1 and up. This added software option ensures the cleanest possible image, perfect for printing or archiving.

"Picture Style" settings
With Picture Style technology and the EOS 40D, photographers can recreate characteristics of their favorite films. Color, saturation, sharpness and contrast settings create noticeable variation in the saved image. In addition to six preset Picture Style settings (Standard, Portrait, Landscape, Neutral, Faithful and Monochrome), users can create three additional settings for their particular photographic style.



Landscape


Setting Description Saturation Sharpness
Standard (default setting) Vivid, sharp images; usable in a wide variety of conditions; optimal for direct printing without post-processing. high slightly high
Portrait Warmer skin tones, with slightly more contrast than Neutral. slightly high slightly low
Landscape Extremely bright, saturated and sharpened images, with emphasis on blue and green color saturation. high green-blue high
Neutral Low sharpening, contrast and saturation:  the ideal starting point for image-editing in the computer. low none
Faithful Accurate reproduction of the subject's colors based on colorimetric data; assumes 5500K light source. low none
Monochrome Black & White images; adjustable contrast, sharpening, as well as color toning and effects of traditional color filters. none (monochrome) slightly high

Spot Metering
The EOS 40D also includes a spot meter function that measures roughly 3.5% of the center of the image.This new metering function, added to Canon's impressive Evaluative, Center Weighted averaged and Partial-metering modes, gives the photographer even more choices for custom-tailored shooting.


Highlight Tone Priority
This vital Custom Function lets photographers get even better detail in bright highlights, even in contrasty lighting conditions. It's beneficial for nearly any type of picture, from mid-day shots on a safari to portraits in sunlight, where a user may encounter bright highlight areas where he or she wants to preserve details. Finally, there's no impact on the camera's shooting speed or burst rate when Highlight Tone Priority is engaged. It takes full advantage of the EOS 40D's new 14-bit per channel conversion, meaning there are 16,384 distinct tones from darkest to lightest in each color channel.
