You can remove the background or backdrop behind an object in a picture with a process called background removal. This process can remove the background in its entirety, or you can choose sections or parts that you desire from a backdrop to be removed.

The advent of digital photography and its accompanying technologies has made background removal an easy editing fix. Before such capabilities were available, background removal of a photograph was a more difficult process.

It was once done in a darkroom under all of the proper temperature and ambient conditions. The film was watched closely while submerged in a working solution. By overexposing the film to the solution, the background was blurred and has a decrease in resolution.

Today, background removal is possible with any digital photo editing software like GNU Image Manipulation Program, or GIMP. GIMP is a special type of graphics editing application that is able to support some kinds of object-oriented (or vector) graphics.

Many online printers offer online storage of your photos which is a great way to back up all of your images. An advantage of storing online is the automatic simplicity and speed it will take to send the printing service an order.

And of course if you store your photos online you have the ability to access them anytime, anywhere from your cell phone. This service comes at no charge from the higher quality online printing services. Not only can you view your pictures through your phone, you can also place an order.

A good printing company will offer an endless array of options to you. Anything from customized postage stamps with your photos on them to cell phone ringer IDs is a possibility. Take the time to see what different companies have to offer different from their competition.

The Canon PowerShot SD500 allocates your pictures to SD memory cards for storage. There’s also direct link to Canon CP Printers and select BJ Printers. This in fact means that you do not need a computer to print pictures.

The Canon PowerShot SD500 makes use of proprietary lithium batteries. The marketed battery life is about 160 shots with the LCD on and about 550 shots with the LCD off. If a long battery life is a necessity, extra batteries are available for purchase at your local camera store so you can take along extras.

Another unusual feature is an elective DC coupler, supported by a flap on the battery/media compartment door. This lets you operate the camera from AC power (by the use of an optional adapter) while you charge the battery in the included external charger.

Overall, the Canon PowerShot SD500 is a smart little camera for the value. A few notes however are that it has some difficulty finding the intended focusing point in Macro mode. Macro mode also has the fault of overexposing pictures when the flash is used except for the bottom area of the image that is dark due to the extended lens blocking the flash.

Be sure however that the Canon PowerShot SD500 is a great ultra-compact camera. From its looks to its capabilities, this camera is impressive. Then once you add on its remarkably unique features, the Canon SD500 stands out among the rest as a contender for a top seller.

One camera to watch available on the market today is the Canon PowerShot SD500 Digital Elph. Coming with an impressive 7.1 megapixel resolution this camera provides superior image quality.

The SD500 executes well on speed and sharpness tests. It also got a fun My Color feature that will be sure to please many kinds of users.

As far as design, the Canon PowerShot SD500 is delightfully comfortable to hold and control. One thing to watch for is that the compact layout of the buttons on the back can be easy to accidentally press during one-handed shooting.

The LCD is a large 2 inches and the optical viewfinder located just above is nice and maintains a smooth, bright and clear image when panning.

All the standard modes are accessible through the mode dial as well as through the menu system, including Playback, Auto, Manual (which lets you adjust white balance, ISO, EV compensation, and color effects), Macro, and Movie.

The Movie mode lets you capture VGA video clips at 30 frames per second. Other modes offered only by way of the menu system include Stitch Assist (for panoramas) and nine preset scene modes.

It also offers a very remarkable shooting mode called My Colors. You can make blues, greens, or reds more animated, or lighten or darken skin tones.

The Color Accent and Color Swap choices generate some out of the ordinary effects.

Color Accentt lets you isolate the color of one object, while the color information for the rest of the photograph is discarded. The product might be a bright red rose in the middle of a black-and-white wedding shot.

Color Swap mode, you select a certain color in a picture on the LCD, and then choose the color you want to switch it with. For instance, you could isolate the rich purple from a flower and swap it with the dusky rose color of the dress ion the person holding the flower. You have to make your color choices before you shoot, so be certain you’re not going to miss the shot.

When it comes time to print your digital photos, you have the choice between matte or glossy. The difference is simple, glossy photo prints have a shiny finish while matte prints have a softer, more subtle finish. The choice between the two is up to you with both finishes having pros and cons.

What chemicals are used when the digital photos are printed will determine what the resulting finish will look like.

Again the difference is easy to tell. Glossy prints reflect light well, are shiny and are very animated in their color. Matte finish however does not reflect much light and colors tend to be more muted than lively.

Glossy photo prints: Glossy photo prints are shiny and are more tempting to the eye. They look fancy and present a high quality feeling to the photo. Glossy photo prints have vibrant colors. Colors also look rich and deep on glossy photo prints.

A disadvantage to glossy is that the ‘shiny’ finish can make viewing the photo in intense light difficult due to the light reflecting from the photo print blinding the viewer. Glossy paper is also more apt to draw dust and fingerprints making the photo dirty over time. Black and white photos do not work as well with a glossy finish as those with a matte finish.

Matte finish: Matte photo prints do not reflect light resulting in them being easier to view in almost any light condition. Matte photo prints are also less likely to attract dust and fingerprints and are less likely to get soiled over time.

Black and white matte photo prints look better than black and white glossy photo prints. On the downside matte photo prints do not have the fancy high quality look that glossy photo prints have. Colors in matte photo prints are less effervescent and less rich than on glossy photo prints.

Following on from Monday’s Post…

It is clear that the optical system of the Canon PowerShot A520 has been thoroughly thought out to make great photos simple. A 4.2 megapixel resolution along with the 4X optical zoom is provided and the Canon PowerShot A520 also features an ISO range of 50 to 400 and a shutter speed range of 15 – 1/2000 sec. making it an impressive choice.

The Canon PowerShot A520 preserves the exceptional level of manual control of previous A-series models, including Program, Shutter priority, Aperture priority, and Manual modes, available via the top-mounted mode dial. The dial also offers five universal shooting modes (Portrait, Landscape, Night Scene, Slow Shutter, and Fast Shutter), as well as Stitch Assist and Movie mode.

A comfortable ease of use with many options is still found in the unchanged menu system. The only improvement to be found here is perhaps to illustrate the scene modes with some on-screen help and sample images along the same lines as what you would find on the Casio Exilim Zoom EX-Z55 for example.

The Canon PowerShot A520’s battery life using the two included alkaline double-A batteries is admirable and the camera is rated for up to 300 shots according to the CIPA standard (using NiMH double-A batteries).

Pictures are stored in SD memory cards with the Canon PowerShot A520. Most cameras today come with at least a 512 MB memory card, some even a 1 GB card. You can also transfer pictures from the camera to the PC with ease using the USB 2.0 interface.

As with almost anything, there is at least one notable issue with the Canon PowerShot A520. Confirmed reports have stated the A520 controls are not responsive enough leading to the camera to being quite slow. A button frequently had to pressed more than once to perform the chosen function.

One of the latest editions to the Canon family is the 4-megapixel Canon PowerShot A520. This nice little camera is smaller and lighter than the PowerShot A85 that came before it. By adding a longer zoom lens and additional new scene modes, this camera is nicely equipped.

Those both experienced and new to photography will be pleased with what the Canon PowerShot A520 has to offer. What’s even tougher to beat than this camera’s features is its great value-for-money appeal making it a camera to consider if in the market for a camera purchase.

Other than the size, the only other noticeable design differences are that the AF assist lamp on the front has moved to the opposite side of the viewfinder and you may notice the microphone has shifted.

The LCD is still the same 1.8 inches diagonally but does have some differences. The LCD is now an f/2.6 to f/5.5, 5.8- to 23.2-mm (35- to 140-mm, 35-mm equivalent), 4X optical zoom lens.

More about the A520 on Wednesday.

For a photographer, there is little worse than the bad feeling that you’ve just missed a fantastic shot because the digital camera battery went dead. It is necessary to bring another replacement battery with you if you are planning to take a lot of photos.

We must know batteries first before we choose one. There are 3 kinds of digital camera batteries that we often use, alkaline battery, Ni-MH battery and lithium-ion battery.

1.Alkaline battery

Alkaline battery is the most common battery in our daily life. There are many brands of alkaline batteries we can find, like Duracell, Energizer, Sony, Samsung, Maxell, etc. Unlike rechargeable batteries, alkaline batteries are not able to circulation use. Once it is drained, you have no option but throw it away.

Advantage: Easy to buy, Cheap (only for who need it temporarily,) and more choice of brands.

Disadvantage: Irrechargeable, Cost too much if often use. Low energy conversion efficiency.

2. Ni-MH battery

Ni-MH battery is a kind of rechargeable battery. You can find it in retail stores in size AA. As the same as alkaline batteries, Ni-MH batteries are not expensive, either, and the voltage and performance is similar to standard alkaline batteries in those sizes. You may pay more money than alkaline batteries when purchasing Ni-MH batteries, however, the ability to recharge 1000 times can save a lot of money.

Advantage: Rechargeable, Great compatibility

Disadvantage: Its durability is less than alkaline battery that has the same specification. Cost too much if use only once. The Memory effect will causes them to hold less and less charge.

3. Lithium-ion battery

Lithium-ion battery (sometimes abbreviated Li-ion batteries) is also rechargeable. Nowadays, most digital cameras use Lithium-ion battery as power supply. It is lighter and more powerful than alkaline battery and Ni-MH battery. Lithium-ion batteries do not suffer from the memory effect. They also have a low self-discharge rate of approximately 5% per month. (which is 30% for Ni-MH battery).

Advantage: Rechargeable, Less weight, Great energy

Disadvantage: Expensive. Its life span is dependent on the number of charge/discharge cycles and the age from being manufactured. It is not so safe as other batteries in some situation.
