I have an 8 megapixel Canon EOS Rebel XT. It is a very good camera, but I notice that when I open images in my editing program that the resolution of the images is always 72 pixels. The size of the image is huge - 3456 X 2304 - but how can I increase the resolution? Any tips on getting sharper images would also be appreciated. Thanks.

The EOS 400D, called the Rebel XTi in North America, is a single-lens reflex digital camera. Canon introduced this unique looking camera in 2006. It’s the successor of the EOS 350D.

Canon considers the Rebel to be the best entry-level digital single lens camera of its kind on the market. It’s a priced below $1,000.00 which makes it affordable especially when the lens is included. It produces some fine images with pure, sharp colors. It’s also very quiet.

They upgraded the CMOS sensor to an impressive 10.1 megapixels. Among the other added features we get a larger continuous shooting buffer, an integrated image sensor, vibrating cleaning system and a more precise nine point auto focus system.

Canon didn’t stop there! They even improved the grip of the unit and gave us a nice 2.5” LCD with 230,000 pixels and a larger viewing angle which replaced an ill-conceived top status screen. The changes Canon made to the newer model has a tendency to underexpose the subject whereas the older versions overexposed.

As a user of this model I’ve come to find out that if you remove your glasses or cover up the view finder it greatly limits the light from entering the unit and giving you an unwanted look. Sort of like a filter for the light. This is a fault in the calibration of the product and can’t readily be fixed by upgrades.

I was personally impressed by the censor as the camera boasts 10.5 million pixels, RGB filter array, built-in low-pass filter and a nice 3:2 aspect ratio.

It outputs in three image sizes that can meet most photographer needs:

3888 x 2592

2816 x 1800

1936 x 1288

The camera allows you to save files in jpeg and large form raw files giving you the ability to connect via USB, video and remote to take your photos from the camera to your computer for printing and/or editing.

Rebel XTi retails at around $800.00 but if you want the optional lens kit that comes along for the ride you’ll be paying roughly $100.00 more. This lowers the bar for other $1,000.00 10 megapixel cameras like the Nikon D80 which was also showcased in 2006. I’m looking forward to upgrading to the 5.6 IS USM lens which is Canon’s fastest standard lens in production to date.

Change Summary And The White Sheet

In the end it all breaks down to the features. The Canon white sheet is impressive! The listing of features, the changes from the older camera to this version, is vast which makes this camera one of the best buys.

* -10.1 megapixel CMOS sensor with improved microlens array, fill factor and lower noise.

* -EOS Integrated Cleaning System

o .Anti-static coatings on sensor surfaces plus anti-dust materials in the camera body

o .Separate low pass filter with ultra-sonic vibration

o .Software based dust mapping / removal

* -Nine point Auto Focus sensor (same as EOS 30D) with F2.8 support

* -Continuous shooting burst up to 27 JPEG and 10 RAW images

* -Single large, bright, 2.5″ LCD monitor with 160° viewing angles (horizontal and vertical)

* -Camera settings and adjustment on LCD monitor

* -Proximity sensor below viewfinder eyepiece to disable the LCD during composition

* -New viewfinder view includes 9 AF points as well as EOS 30D style status bar

* -Picture Styles, larger range of image parameter adjustment (same as EOS 30D)

* -Improved user interface

* -Image magnification available in record review

* -Histogram available as brightness (Luminance) or RGB (Red, Green, Blue)

* -Three settings for long exposure noise reduction (adds Auto option)

* -Auto rotation with three options (not recorded, record don’t rotate, record and rotate)

* -Automatic storage of setting adjustments (no longer requires a press of the SET button)

* -Improved print / share / direct print features

* -Lower introductory list price ($100 lower)

One feature that is revolutionary is the way the camera handles dust on the sensor! Dust, unfortunately, is attracted to electronics. Canon, after years of denying the existence of dust being able to get on the camera sensor, finally admitted it and fixed it!

Dust pretty much shows up from several sources but typically it’s from fragments released by the moving components inside the camera. Before you had to take the camera apart to clean it or use some sort of blower or mini vacuum.

Canon took care of this issue by implementing the following:

* Used materials in the mirror box and shutter chamber which are less likely to generate dust.

* Improved the body cap, again to not generate dust.

* Used anti-static coating on the sensor surface.

* Created a new separated anti-alias filter which vibrates to shake off dust.

* Added a Dust Delete Data feature which can map stubborn dust to be removed in software.

This all helps keep your camera healthy for prolonged use. You can smile as your fellow photographers take time out of shoots to try and swab out their cameras while you continue to snap gleefully away.

As I’ve mentioned earlier there are two separate versions of the Rebel XTi but what comes in the box? And what doesn’t?

* The 10.1 effective Megapixel Digital Rebel XTi camera body

* 18 - 55 mm F3.5 - 5.6 Mk II EF-S lens [lens kit only]

* NB-2LH li-ion rechargeable battery pack

* Battery charger

* Neck strap

* Eyecup

* Body cap

* USB cable

* Video cable

* CD-ROM featuring EOS Digital Solution and software instruction manual

* 179 page camera manual (printed)

Unfortunately the one drawback I found was that the camera did not come with a memory card. This can hinder your potential. So when you’re going out to buy keep that in mind. CompactFlash cards are fairly inexpensive these and depending on your needs I’d do what I did and pick up a 1GB card. For tech heads out there the XTi supports Type I and II cards and even the microdrive. You might also want to pick up a 50X or better CF card.

I love photography and my work dictated the need for the lens kit so I sprung for it. When you get the kit you also get Canon’s second gen 18-55 mm EF-S in the box. It’s not the best and aperture can vary to small and unclear. I had little use for this one since the other lenses are quite nice.

The Rebel XTi uses the same lithium-ion battery as its predecessor. The energy value of the batter is right in the middle of the pack with the life of it about 10% less. Bigger LCD takes more power.

Personally I love this camera. I use it as a back up to my professional setup. If you want quality for price and reliability then I suggest the Rebel XTi. It makes a great mid-range camera for everyday photography needs such as real estate agents, car dealers and family vacations.

I have a Canon EOS 350 D. Today I bought a Opteka 500 mm 8.0f lens. The instructions with the lens were not enough for an amateur photographer like me.

Canon, which is well known throughout the world for its quality cameras, released the Canon EOS Rebel digital camera on August 20th of 2003. At this time there were other well known digital cameras on the market but the new features of the Canon EOS Rebel digital camera made this digital camera well worth looking into.

The various camera experts who have reviewed this Canon camera state that the price tag of $900 makes this a moderately priced digital camera that you can buy in various countries around the world.

If you are looking to buy your camera outside of the United States you might want to be aware of what the Canon EOS Rebel digital camera is called in other countries. For instance the Canon EOS Rebel digital camera will be called the Canon EOS 300D in Europe and in Japan you will hear it being referred to as the Kiss Digital.

For the digital camera enthusiast there is also a Canon EOS Rebel digital camera kit that can be bought. This kit contains an EF-S 18-55 mm 3x lens. The price of the entire digital camera kit is $100, more than the single camera.

The various specifications of the Canon EOS Rebel digital camera include a 6 megapixel CMOS sensor and image processor. The sensor and image processor are housed in the inexpensive plastic body of the digital camera.

To help their customers buy this camera the people at Canon have given the Canon EOS Rebel digital camera a pentamirror instead of a pentaprism. These various modifications have helped to reduce the cost of this camera, which therefore makes this digital camera more affordable.

There are a host of new features that you can find in the Canon EOS Rebel digital camera. These features include contrast, saturation and sharpness settings which can be adjusted for your various needs. There is also a new default parameter setting on the Canon EOS Rebel digital camera which is referred to as Parameter 1.

The Canon EOS Rebel digital camera was the first digital camera to support the use of a new lens called EF-S. The S in the lens’s name stands for short back focus. This lens can only be used with the Canon EOS Rebel digital camera as the other Canon Rebel series cameras will not have the necessary support for this lens.

For the enthusiastic novice or professional photographer, the Canon EOS Rebel digital camera is for you. The many great interesting features and functions to be found on the camera coincide very nicely with the reasonable price tag on it which only makes the camera more appealing.
