Canon Digital Camera Guide

Filed under:Photography Hall — posted on November 2, 2009 @ 9:37 pm

Canon digital camera innovations have always been at the forefront of photographic innovations and their compact digital cameras package a variety of functions into a deceptively small Canon digital camera body. These are particularly attractive to a wide range of users because of their light weight, ease of use, high image quality and high functionality. Canon digital camera experts are highly experienced in camera manufacturer, leading-edge optical technology, ultra high-precision mounting technology, electronic device technology and color management technology amongst others. All of this experience and expertise is combined to produce the Canon digital camera PowerShot series and the PowerShot DIGITAL ELPH/DIGITAL IXUS series.

Throughout their continuing research, the Canon digital camera development team has collected a large amount of photographic data and also made broad statistical analyses of the frequency involved in taking photographs. This data led to the creation of the Canon digital camera Photographic Space which is a graphical database of information relating to the relationship between surrounding brightness and distance between a Canon digital camera and the subject relative to the focal length and position of the zoom lens when pictures are taken.

The Canon digital camera Photographic Space led to the development of a new scene-recognition technology called “iSAPS” (intelligent Scene Analysis based on Photographic Space) Technology. Canon digital camera iSAPS Technology analyses the scene to be photographed and makes optimal adjustments of a number of key functions, including auto-focus, before the shutter is pressed.

The Canon digital camera iSAPS Technology closely estimates the camera-to-subject distance based on the lens focal length, zoom position and surrounding brightness which guarantees the most accurate exposure and white balance settings for the overall conditions.

At the high end of the Canon digital camera range are their single-lens reflex, or SLR, cameras. The Canon digital camera company has created ultra-high-precision imaging elements and high-performance digital imaging engines so that their digital SLR cameras possess the same ease of operation as their 35mm film counterparts but produce exceptionally high-quality images.

The Canon digital camera imaging engine, or DIGIC II, creates image data from signals output from a CMOS, or complementary metal oxide semiconductor, sensor. The CMOS sensor is really the brain of any digital camera. Canon developed the Canon digital camera DIGIC II high-performance imaging engine directly due to the increasingly high resolution CMOS sensors. With the help of a high-capacity DDRS DRAM (double data rate SDRAM) as the buffer memory, the Canon digital camera DIGIC II processes high-resolution images at ultra-high speeds.

That Child Is Your Photographic Friend

Filed under:Photography Hall — posted on February 2, 2009 @ 3:57 pm

Your child is your friend. Yes. Your friend.

Forget, for a moment, about all the sleepless nights, tantrums and constant demands over the years. Forget about the lack of authority you seem to have and the way in which your child can manipulate you at will. Forget also about the costs to your health and bank balance that your child has caused since birth.

Your child IS your friend.

Why?

Because children love having their photograph taken. They never tire of it. Daytime, night time. Indoors or out. They will always be ready and willing. Whether it be a few snapshots in the garden or a formal portrait session, they will be there to help you.

They will strike any pose. They will sit, stand, lay, jump. They will have a multitude of expressions to share - smiling, laughing, sad, serious. It’s all there waiting for you.

They love props - something to hold, something to shake, water, material, sand. And dressing up is all in a day’s work for the average child.

And, when the images are taken, they won’t criticise your efforts even if you, yourself, consider them to be substandard. But if the images you produce are lacking in that certain something, then your child will be there once more, to help out and pose again.

Yes, make friend with that child.

When a Digital Zoom is Needed

Filed under:Photography Hall — posted on January 5, 2009 @ 9:59 pm

You’ve been told that you should disregard claims of
large digital zoom ratios and have been warned that to use
a digital zoom is to ruin the picture with visible artifacts and pixels. To a certain extent, these statements are true but they don’t tell the whole story.

Digital cameras that feature an optical zoom and a digital zoom offer the option of using one or the other or even both together. An optical zoom lens of 28 to 200 mm may not be enough in some situations. This is where the digital zoom comes in handy.

Say you are at a football game and want to get a close up of your son in action. A 200mm lens setting would probably include three or four football players in the scene, making it difficult to recognize faces. A two times digital zoom makes the focal length 400 mm, cropping the scene into a two football player picture. A four X digital zoom setting will garner a head and shoulder close up of one football player.

At two X digital zoom, the number of pixels are cut in half but digital processing and interpolating between pixels will smooth out the image with very little loss in quality. If your digital camera starts out with 8MB of pixels, the final result of 4MB will still enlarge to over eight by ten size without losing quality. At four X digital zoom, the pixels are reduced to 2MB which will visibly degrade the image somewhat. This sacrifice in quality is often acceptable if you capture a fantastic shot of action.

Other subjects that would benefit from the use of the digital zoom are bird photography, wild animal photography, candid people shots and sport events of all kinds. While most photographic images are covered with the normal optical zoom range, sometimes the digital zoom can save the day.

Digital Cameras: The New Generation

Filed under:Photography Hall — posted on December 30, 2008 @ 9:24 pm

With the advent of modern scientific tools, life has become highly sophisticated. There has been a significant evolution in the technology and the lifestyles of the human beings. One of the fine examples of evolution is the advent and craze for digital cameras. A digital camera is equipped with an electronic photosensitive sensor. The photographs are stored digitally in the in-built memory of the camera and can be directly uploaded on a computer for viewing and printing. There is no need for buying films or getting them processed with these modern gadgets.

The craze for using the cameras can be traced back to the 16th century. Man has used the cameras to capture the history or larger-than-life-events. As the science has expanded in this ever-shrinking world, the expansion of camera technology has soared to new heights. From the normal camera, the world has stepped into the era of digital cameras. These cameras have brought in a complete revolution in the camera industry.

The features of digital camera are so unique and advanced, that handling the camera has become a child’s play. Before you go and buy your digital camera, you should know some basic information on these modern weapons. You must pick the right camera to capture your precious moments.

How a Digital Camera Works

The basic difference between a digital camera and normal camera is that a normal camera uses a film to store the photographic images, while a digital camera uses an in-built memory to store the photographs in digital format. The lens of the digital camera focuses the light directly on to a semiconductor device. This device records the light electronically. The computer then breaks and stores this electronic data into digital data, which gets stored in the memory of the camera and can be transferred on to a computer.

Charge Coupled Device (CCD) is employed as the image sensors in the digital cameras. These charge coupled devices are responsible for converting the light into electronic forms. The CCD is made up of light sensitive diodes which accumulate electrons when hit by a beam of light. The prominently used CCDs are the triple CCD cameras. The product of these cameras is superb as the three CCDs react separately to the three basic colors such as red, blue and green. The end result is fantastic. These electronic symbols are then stored as digital data in the digital camera.

Buying a Digital Camera

The modern market is booming with various types of digital cameras. Digital cameras vary in function and most of all their mega pixel quality. If you plan to buy a digital camera, prior information about digital cameras would be an added advantage.

First of all you should figure out your need for buying a digital camera. The need for a digital camera helps you narrow your search for the best camera, suited to your requirements. You might want to buy a digital camera for posting photographs on the net, using photos for professional graphics work, to get a better-quality photographs and much more.

Next thing you should determine is the resolution you require in a digital camera. There are broadly 5 classifications of resolutions for digital cameras. These resolutions are expressed as mega-pixels. The higher the resolution of a camera, the better quality photograph it will produce. There are cameras available with 6 and 7 mega-pixels however, anything above 4 mega-pixels will produce really great photos.

Now buying a digital camera should be easy!

A Guide to Underwater Camera Cases

Filed under:Photography Hall — posted on December 28, 2008 @ 6:21 pm

If you are buying a new underwater camera or video camera, you will need an underwater camera case. And this case needs to be watertight, airtight, dustproof, crush resistant and designed to keep your valuable equipment safe from all the elements. It may also be rustproof, pest-proof, and chemical resistant to oils, fuels and solvents. It may have flame retardant included and be molded with a UV stabilizer, making it ultraviolet resistant. (This will prevent the plastic from becoming brittle if left in the sun for extended periods of time.)

Some of the best cases are subjected to a 24 hour submersion tests, manufactured to exceed of 400 lbs of stacking, and a drop test at 48 inches.

Some have a “”pressure release purge valve”" that guarantees a perfect seal by incorporating its own O-Ring under one of the latches. And you will never forget to set the valve since it automatically activates when closing the case. Pressure is released as you open the latch.

Removable Accuform foam may be included with your underwater camera case. This is vertically pre-scored, high-density foam that is easily formed to provide a snug fit to protect your equipment from the abuse of your toughest adventure.

Digital Photo Printer Reviews - Which Is Best For You?

Filed under:Photography Hall — posted on December 22, 2008 @ 10:48 pm

The old days of sending your film out to be developed and waiting days to see what they looked like are quickly fading into the past as today’s photo printers make everything so much easier and quicker. Now all you have to do is just snap your photos, hook up your camera to the photo printer and in seconds your beautiful prints are pouring out before your very eyes. It’s really that simple!

Of course, you can also upload your photos to your computer and edit them before printing too. With all of the photo editing software that is available for use today, there is no reason that your photos can’t look like like they came straight from a photo lab as they come out of your printer. But which photo printer should you buy?

The term photo printer is often used for just the small specialized snapshot printers that only produce 4 X 6 photos and no enlargements, but these days even their larger brethren are being called photo printers since that is the main use that many folks are putting them to at home. Here are a few digital photo printer reviews to help you find a high quality printer for your needs:

If a snapshot printer happens to be all that you really need, a good unit to look into is the Epson PictureMate Deluxe Viewer Edition that comes with a 2.4 inch LCD preview screen and is really economical to operate, producing great 4 X 6 photos that only costs on average a little over 20 cents each.

If a larger inkjet photo printer is needed, the Canon Pixma iP4000 is almost universally agreed to be one of the best in it’s category. It uses four separate ink cartridges for improved image results and a special black ink that makes photos just pop off the page with contrast. It is also a great multi-function printer, but it makes an excellent photo printer as well.

For those who want even more professional results, and capability to print enlargements on up to 13 X 19 inches, the Canon i9900 would be a great selection. It uses 8 ink cartridges with 2 picoliter droplets to produce outstanding photo results, and can even print a 13 X 19 borderless print in under three minutes, making it blazing fast too.

Any of these digital photo printers would make a great choice, but we tried to select a printer for each level of photography from that of just wanting to print snapshots alone, to those who are more serious about their photography, and then even to the most demanding of serious photographers. All of these three printers have received very high marks from online independent and consumer reviews, so a selection of any one of them should be a very wise choice.
