2010 Emerging Pro Tech

Canon Camera Technology

Canon’s full-frame DSLR cameras use the proprietary, world-renowned CMOS imager. They deliver superior low-light, high-ISO performance and sharp, richly detailed images in all shooting situations. Large RAW image files captured by Canon CMOS allow you to express your creativity and unique vision at the highest quality.

Canon’s Integrated Cleaning System assures that your best shot won’t be spoiled by lingering dust on the CMOS imager. Sensor cleaning the EOS way is fast, silent and thorough. It’s another example of the way Canon provides the best experience for professional photographers and makes your workflow easy.

Canon’s Picture Style feature allows you to preselect image effects matching your photographic expression or the subject’s unique characteristics. Choose Standard, Portrait, Landscape, Neutral, Faithful or Monochrome—or customize your own style by adjusting parameters like Sharpness and Contrast.

Canon EOS cameras and printers are fully compatible with the latest versions of Window and Mac operating systems. Look for the official Windows and Mac symbols—your guarantee of compatibility.

The brain of every Canon digital camera resides in an ASIC (application-specific integrated circuit) called the DIGIC Processor. The latest version, the DIGIC 4, offers faster image processing, improved high-ISO performance, Face Detection during Live View and enhanced video-capture features, including 1080p HD recording capability.

While most Canon EOS camera users transfer images to a computer for electronic distribution or for printing via an image-editing program, Direct Print System makes it possible to enjoy the convenience of computerless printing. This function works with many Canon printers, including the compact, portable 4×6 snapshot models.

Perhaps the majority of  Canon EOS camera users transfer images to a computer for electronic distribution or for printing via an image-editing program. PictBridge, an industry-standard protocol, enables the convenience of computerless printing. This function works with any brand of printer that incorporates PictBridge technology.

Don’t waste time with slow transfer protocols. Canon EOS cameras offer Hi-Speed USB connection, so image transfer, camera control and other tethered functions happen faster.

Several Canon EOS camera models sport large, bright three-inch LCDs. The EOS-1D Mark IV and EOS 7D offer ClearView II technology, which combines more than 900,000 pixels, a 160-degree-wide viewing angle and exceptional brightness. It also consumes less power and has a smaller overall footprint compared to conventional LCD types.

HDMI (High-Definition Multimedia Interface) allows transfer of any uncompressed video format, including full HD, via a single cable. Canon utilizes HDMI to assure fastest possible transfer rate and maximum compatibility with other types of devices.

You can capture images while viewing them on your camera’s LCD monitor. The feature is called Live View, and it can be used when shooting still images or movies. Remote Live View, a similar feature, allows you to connect your camera to a PC and shoot remotely while viewing the capture screen. Remote Live View requires Canon EOS utility software, which is included with EOS cameras.

Full HD, which is sometimes called “1080p,” features a frame size of 1920×1080 pixels and is the highest quality currently available. The Canon EOS 5D Mark II, for example, offers full-HD, 1080p video capture. The “p” signifies “progressive” scan and means that each image is captured as a full frame of video. This system is preferable to the alternative “i” or “interlaced” video in which two consecutive fields are captured and reassembled into one full frame.

Think of shooting 100 images each and every day for more than eight years and using the same camera shutter throughout. That equates to shutter durability of 300,000 cycles. What that means to you is utmost reliability. It signifies that your camera has been built to exacting standards using the most durable components possible. Your Canon EOS camera won’t quit until you do.

The 63-zone dual-layer metering sensor found in the Canon EOS 7D  utilizes both autofocus and subject color information for optimizing exposure and image quality. Part of the EOS 7D’s 19-point AF system, this advanced metering sensor minimizes exposure errors and focus errors caused by different light sources because it has color-measurement ca

The Canon EOS-1D Mark III can capture at a rate of up to 10 frames per second. At this blistering speed, you can create an extended sequence of a moving subject instead of just one single image. This rapid image processing relies on an image buffer that can handle more than 100 megapixels of image data per second.

The Canon EOS 7D features an all-new cross-type, 19-point autofocus system with improved AI Servo AF subject tracking and user-set AF area-selection modes. Any of the 19 precision, cross-type AF sensors can be selected automatically or manually. Combined with Canon’s light-source detection AF, the system automatically adjusts focus as needed to compensate for variations in light sources. Subject tracking even works when shooting close-ups.

For maximum shooting comfort, Canon’s Intelligent Viewfinder delivers 100-percent field of view, a wide viewing angle of 29.4 degrees and a high magnification of 1.0x. It features a glass pentaprism, user-defined dioptric adjustment and an electronic level. It also features a newly designed transparent LCD display, which allows a number of viewfinder displays to be overlaid (or hidden) by simply touching one button.

Canon Lens Technology

Full-time manual focus is a feature common to all Canon lenses that have ring-type USM. Once autofocus has been achieved in AF mode, photographers can fine-tune the focus by slightly adjusting the focus ring. This is useful when the subject is complex or when the photographer can’t decide exactly which spot to focus on.

Canon began producing USM (Ultra Sonic Motor) autofocus motors because they’re nearly silent and highly responsive. USM is powered by efficient ultrasonic oscillation energy, and since the motor can be placed in the ideal position for a particular lens, focus is fast and accurate. USM autofocus motors also allow for full-time manual focus, so photographers can fine-tune the focus if they choose.

Lens elements are ground and polished using a rotating technique that produces an unavoidable spherical shape. This shape isn’t ideal for every situation, so some lenses are built using harder-to-make aspherical elements that can focus parallel rays of light on a single point. Manufacturing tolerances as strict as 0.1 micron (1/10,000 of a millimeter) must be observed, which explains why aspherical surfaces are so hard to produce. Canon uses aspherical elements in certain L-series lenses for superior results.

Ultralow-dispersion glass elements possess many of the characteristics of Fluorite elements (low refractive index, low dispersion and exceptional partial dispersion compared to regular glass). The highest-grade UD glass, called Super UD, is so potent that a single Super UD component can produce the same optical corrections made by two conventional UD elements. Super UD glass significantly reduces chromatic aberration and helps reduce overall lens size.

Certain Canon lenses feature a circular aperture diaphragm unit. It has curved aperture (CA) blades that provide a more rounded opening when the lens is stopped down. This method delivers pleasant bokeh (out-of-focus images) and makes defocused highlights appear round. Canon lenses that feature CA also are equipped with Canon’s Electromagnetic Diaphragm, which enables accurate aperture control and nearly silent operation.

Calcium fluorite is a naturally occurring mineral with exceptional optical characteristics. It has a very low refractive index, causes low dispersion and excels at transmitting UV and infrared light waves. Fluorite produces exceptional images, particularly when used in super-telephoto lenses that might otherwise fall victim to chromatic aberration. Canon was the first camera manufacturer to incorporate fluorite elements in lenses.

Floating construction preserves optical quality over a range of different focusing distances. When used in lens designs that employ aspheric elements and rare-earth glass, floating construction helps Canon lenses produce excellent corner-to-corner sharpness from close-up to infinity.

Unsharp images spoiled by camera movement are the number-one cause of bad pictures. Camera shake causes light from the subject to bend relative to the optical axis, producing a blurred image. Canon’s in-lens, optical image-stabilization system stops the effect of the shakes via the shift method in which a lens group parallel to the focal plane is moved slightly. Canon’s image-stabilization system allows steady handheld shots at speeds up to three stops slower than otherwise possible.

Image stabilization compensates for angular camera shake. For Macro photography, it’s desirable to compensate also for shift camera shake (movements parallel to the imaging plane), which have greater detrimental effect when shooting close-ups than during other types of photography. Yet another Canon first, Hybrid IS effectively compensates for both angular and shift camera shake simultaneously during close-up shooting.

An inner focusing lens has the focusing lens-element group in front of the diaphragm, whereas a rear focusing lens has the focusing lens group behind the diaphragm. Both systems allow lens designers to keep the focusing groups small, and they reduce the load on the focus actuator. The result is faster AF speed and small
er lenses. Also, since the front element of the lens doesn’t rotate during focusing, it’s much easier to use a polarizer or special-effects filter.

Canon Print Technology

Print edge to edge or add a border of your own. Canon PIXMA professional printers offer full borderless printing, whether you’re producing large masterpieces or simply knocking out a few 4x6s.

Speed counts—when shooting, when working in the digital darkroom and when making inkjet prints. Canon professional printers are designed to suit your workflow. They keep you working instead of watching and waiting. Some models can print an 11×14 (on 13×19-inch paper) in less than a minute and a half.

Canon professional printers are fully compatible with the latest versions of Window and Mac operating systems, so you’ll be up and running instead of looking for missing drivers and absent DLLs. Look for the official Windows and Mac symbols—they’re your guarantee of compatibility.

Don’t waste time with slow transfer protocols. Canon printers, like Canon cameras, offer Hi-Speed USB connection, so image transfer, camera control and other tethered functions happen faster.

Ambient Light Correction
Fine-tune your prints with Ambient Light Correction3. This feature optimizes color output to match  the specified lighting condition you would display in.

Auto Photo Fix technology automatically analyzes images and categorizes them into one of five types: Portrait, Scenery, Night Scenery, Snapshot with Scenery, and Snapshot with Night Scenery. It then applies optimal image and multizone exposure correction. As a result, your print is optimized, area by area. Faces that are backlit or underexposed are automatically brightened with corrected color that delivers more accurate skin tones.

Canon printers use FINE (Full-photolithography Inkjet Nozzle Engineering) to provide stunning detail, fine gradation and resolution of up to 4800 dpi (dots per inch)4. The result is professional, high-quality prints that surpass even the highest standards.

With the High-Performance Individual Ink System, Canon printers use eight or 10 individual ink tanks to ensure that the colors in your digital image are represented as accurately and faithfully as possible. By adding additional Gray, Black, Photo Cyan, Photo Magenta and other intermediate colors, Canon professional printers extend the color gamut well beyond the normal boundaries.

The revered 10-full color pigment LUCIA Ink system includes gray, black and matte black inks that collectively produce monochrome photographs of unrivaled quality when using the professional finish and texture of Canon Fine Art Photo Papers. These genuine Canon papers combined with LUCIA Inks provide phenomenal photo vividness and longevity.

Inkjet printers spray tiny droplets of ink to form the image. The printhead heats ink that’s confined in a tiny cavity to extremely high temperatures until it literally explodes and blasts itself through a tiny opening as a microscopically thin stream. The volume of ink is measured in picoliters (pl), and naturally, the smaller the volume, the tinier the dot. A picoliter is one-trillionth of a liter (in other words, one-millionth of one-millionth). Canon’s patented printheads can fire ink droplets as small as 2pl on the PRO 9000 MKII and 3pl on the PRO 9500 MKII.

Avoid paper jams—Canon’s Straight Paper Path increases printing speed, keeps paper flat and helps enable the use of print stock of varying thicknesses. It’s just one more way Canon facilitates the workflow for professional photographers.

You don’t even need a computer when your Canon printer is matched with a PictBridge-compatible digital camera, DV camcorder or camera phone. In most cases, you’ll want to download your image files, sort and process them using professional browsing and editing software, and so forth. But being able to knock out a quick proof without turning on a PC can be a real time-saver.

The ChromaLife100 system2 combines the benefits of genuine Canon dye-based ink and photo paper with FINE print head technology to produce long-lasting, beautiful prints with a wide color gamut for vivid coloration and high glossiness. Prints are estimated to last for 100 years or longer when stored in an archival-quality photo album, providing outstanding fade resistance.
