It seems that every month, if not every week, different manufacturers are coming up with the latest digital cameras to entice potential clients. And it’s just not working for us!

After spending sizeable amount of time at the mall figuring out which is the best digital camera for us, we finally have enough money to buy for that eye-popping, 7 mega pixel, 10x digital zoom, potable, candy colored, up to 512MB expandable memory of super hi-speed SD memory card and not to mention very portable, (that will be the envy of almost everyone we know). We march to the mall armed with our life savings and lotsa pride in ourselves, when we pass by a new display - an eight mega pixel, up to 1G expandable memory, with built it mic and stereo surround, video playback capable, with 22 scenic modes kind-of-camera. And we sigh because the producer of this amazing gadget claims that this is the best digital camera yet out in the market. And so as we always want to have the best, armed with our life savings and a few credit cards, we buy the “best digital camera.” But then again, that doesn’t last too long, after two months or so, there’s another “best digital camera.”

And so it confuses us. What makes a digital camera, the best digital camera?

Well, there are certain factors to consider when looking for the “best digital camera” for us.

MEGAPIXELS. One of the most important features of digital camera to make it into the best digital camera category is its mega pixel property. The higher the mega pixels the better the actual photograph will come out. A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera. This means that as you enlarge the picture, you would get more detail and less blurry colors.

LCD SIZE. The best digital camera will always have a large LCD to help you frame your subject without having to squint to the viewfinder. This is also helpful when reviewing your images, some cameras enable touch up and editing features with its LCD. A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher.

ZOOM. Most digital cameras have both digital and optical zoom. A higher optical zoom is always better than a higher digital zoom. Digital cameras are usually furnished with optical of between 3x to 10x. The better the optical zoom, the higher it climbs up to the best digital camera category.

MEMORY CARD. Always make sure that your memory card is the right one for your digital camera. There are different types of memory card like the xD, SD, Flash card and the likes. And these types of memory cards go with certain types of digital cameras. of course memory storage is also up there in choosing the best digital cameras. Choose the size of memory that you need, if you’re a photo junkie, you might need more than 32MB. Memory cards can go up to 1G.

The key point to find the best digital camera is to find one that will best fit you and your lifestyle. Don’t just buy the latest or the one that claims they are the best digital cameras out in the market. You wouldn’t want to buy a DSLR and use it with your home activities or family outing and have to lug it around?! Or you don’t want to buy the latest point and shoot camera when you’re serious about being a professional photographer. (Of course, you can use this for starters, but if you’re not a novice photographer anymore, you wouldn’t want to get this kind of camera.)

Actually, the best digital camera is the one that you will enjoy and use. Not the type that you’ll just leave rotting in its box or after a few weeks of usage or so, up there in the attic.

Barney Garcia asked:


Gone are the days when you needed to hire a professional photographer to click pictures on festivals and family occasions like birthdays and weddings. With the digital camera you can click A-grade pictures and even video record events. There are no hassles of developing pictures and no need to wait for weeks to view them.

A digital still camera helps to obtain pictures in digital format. It has a rear LCD screen to view pictures that are taken and its quality is specified in megapixels. Photographs are transferred to a computer using USB. Another type of camera, compact digital cameras or digicams permits limited motion photography. They are easy to operate and focus and enable a larger depth of focus. They are great for taking pictures of landscapes and for casual use.

The camera sensor determines the resolution of the camera. It converts light into digital data and has done away with the role of film that is used in traditional cameras. The sensor collects light in a feature called buckets. Each bucket is a pixel and is turned into an RGB image where each pixel represents several colors. Cameras are in fact compared on the basis of pixels. While pictures are commonly transferred to PCs and cell phones using USB, infrared and Bluetooth are also gaining popularity as seamless methods.

Digital cameras are so popular that even mobile phones include a digital camera. Some these permit only still photography while others enable short video clips as well. Some laptops and PDAs contain integrated digital cameras and some camcorders also have one built into them. Unlike traditional cameras, digital cameras require memory to store data. Flash memory, floppy disks, and CDs are some storage devices.

Digital cameras require high powered batteries to power them for a significant length of time. Some batteries are intended for single use, while others are rechargeable. The rechargeable ones, however, cannot provide power to the camera for a very long time.

Modern digital cameras have made it possible even for the layman to take perfect pictures. This is because they contain features for red eye reduction, trimming, and monochrome, as well as anti-dust caps and vibrators. As some television ads show, you can record your child’s first steps or first words using a digital camera. With digital cameras you can also delete pictures that haven’t been clicked properly or in which you don’t look good. This is another plus over traditional cameras.

Darren Mclaughlin asked:


The cell phone manufactures have been on a roll lately. Companies like Palm are releasing huge sales numbers because of products like their Treo, SmartPhones with an extended range of features over traditional handsets. It’s not hard to understand why this migration is occuring: SmartPhones are light years ahead of their predecessors and have increasing video capabilities, which make them very attractive to the average consumer.

What are SmartPhones? Smartphones are basically what you get when you merge cell phones with PDAs. They’re a handheld computer device, which also doubles as your phone. This comes in very handy to an increasingly mobile generation. As the complexity of people’s jobs continues to grow, the added need for video has become apparent. SmartPhones address that need by providing top-notch video quality. In fact, SmartPhones are now capable of VGA resolutions at 640 x 480.

SmartPhones are capable of internet communications, as well as doubling as easy-to-use camera-phones. You have the best of breed of camera-phones as well as PDAs, entwined into a sleek package that also handles all of your voice calling tasks. SmartPhones can even serve as geo-locators, if you’re lost, so to attempt to call these cell phones does not do them adequate justice. A modern SmartPhone is to a cell phone what an Ipod is to an Eight-Track player.

Recent months have also seen the introduction of several search and directory services that are meant to tap into the huge demand for local cell phone calling services. With SmartPhone sales expected to top 123 million in 2006, the number of subscribers who are willing to pay a few dollars per month for subscriptions is growing. Both Google, Inc and InfoSpace have revealed plans for SmartPhone search that are extremely sophisticated. The nice thing about such an increase in service providers, is that it generally facilitates a rapid expansion of the market. And with increased market share, lower pricing occurs, which results in even more units being sold.

This means the golden age of SmartPhones is upon us. If you look for the power of a handheld computer, with the communication ability of a cameraphone, then you need to seriously shop the SmartPhones. If you plan on buying sometime later in 2006, you most likely will be able to get a VGA screen, so if higher resolution is important to you, I suggest you hold out. Many SmartPhones now have advanced user management, so you can easily manage the custom settings for individual users.

This can come in very handy for someone who shares access to their SmartPhone. There is a flood of mobile video content being made each day now for mobiles, so you can soon expect to watch your favorite television shows and movies, all while driving! Just kidding. Seriously, SmartPhones are so engaging, I suggest you’re seated when you use yours. If you’ve been putting off your decision to purchase a SmartPhone, please look into it now.

Gill Critchley asked:


Camcorders are great gadgets to have as they allow the user to record moments that they would like to remember and watch again and again. Due to this love of camcorders, there are now many different makes and models available, some at very reasonable prices, so many more people can enjoy recording days and events that they want to retain in their memory. One of the most popular models is the Sony Handycam HDR-SR11. This camcorder is a top-of-the-range model that sells for around £750 and is considered one of the best hard drive models. This is a Sony camcorder that has had face recognition added to its list of features and this helps the camcorder then set the exposure and the focus. The x.v.Colour is still included in Sony camcorders and this is their name for the xvYCC colour space. The SR11 also comes with a remote control that makes a positive difference to the colour of the picture if you hook up the camcorder to your TV. This Sony camcorder also includes Picture Motion software. This lets you view your footage and make basic modifications to it. Another camcorder that’s out at the moment is the Canon FS100 and this is priced around the £250 mark so it is a lot more affordable. As Canon camcorders go, this model has very high quality looks regardless of its low price. This Canon is small and stylish and also has an expansive feature set, however, the reason for this device being so cheap is due to the quality of its video, the footage is not as clear as on some camcorders.

Due to many people wanting to record their precious memories, camcorders have become very popular. The colour space used in Sony camcorders is called x.v.Colour. As Canon camcorders go, this model has a small and sleek design for a very affordable price.

John Mce asked:


The new breed of mobile phone is thriving at the moment and the market is starting to flourish with models being introduced from all angles. Previously the iPhone dominated this sector but since everyone’s familiar with the smooth touch screen and slick cover flow it’s just so last year.

Now consumers expect more from their multimedia devices and the Finnish king of mobile phones is adding to the competition. Nokia has just released the 5800 XpressMusic, the touch screen handset that’s an answer to the challenges fronted by Apples iPhone which has hogged much of the market attention since its release last year. In addition Google recently launched its G1 device running on its new Android platform which had stirred up a lot of interest in the tech community. The Blackberry is well established as the smartphone for business for those who don’t want to leave the office, and Research in Motion have announced that a touch screen is in production with the title of the Blackberry Storm.

So Nokia, after concerns were raised about its slipping grip over the mobile market, has got its foot in the smartphone door with a mobile capable of all the usual; web browsing, push emails, digital camera and video playback facilities. But the real crux of the 5800 XpressMusic launch is the Comes With Music part of the promotion where users get unlimited access for a year to the 5million strong database of tracks Nokia has managed to amass with the major labels of the music industry. Amid the fears and hysteria surrounding illegal downloads and file sharing via the web Nokia are hoping this package offers a viable and affordable alternative for children and parents over the Christmas period.

This is a positive step for consumers. Not only is the new smartphone offering a fresh and alternative business model for downloading music rather than just from iTunes, but also with an influx of portable media devices there will be more choice for consumers therefore prompting makers and service providers to be more competitive with their rates. In addition the new Archos 5 media tablet has been released. It’s an excellent digital content device letting you watch video in formats MP4, AVI and WMV as well music formats MP3, WMA and AAC. You can play Flash based games that look striking on the clear as crystal 5-inch screen. You can browse the web and check your emails as well as listen to digital radio. Of course it’s not technically a phone but it is an impressive piece of equipment nonetheless.

With Microsoft penned to enter the fray as well the smartphone market may soon be saturated with quality mobile kit all at competitive prices, good news for the electronics consumers.

Jerry Cahill asked:


Creating and editing videos has never been easier than with digital video cameras. A digital camcorder provides a convenient way to create movies and put them on tape, DVD or even the internet. As easy as it may seem it may still be prudent for you to understand some basics so that you can get the best quality camcorder for your money.

There are some things to remember when shopping for a digital camcorder. You should pay attention to a few key features of digital camcorders. The viewing screen is one of the most important and relevant factors of the entire device. Remember that you will use this screen not only for shooting your movies but for the convenient playback feature. You will want to be able to adequately view your playback.

Of utmost importance is the lense of any camcorder. Most camcorders sold today feature at least a 10x zoom lens. This is adequate for most purposes. Often higher zoom levels are not able to maintain a quality video so they may not be useful.

All camcorders offer one of two types of image stabilization. They are electronic or optical. Image stabilization is incredibly important. The electronic stabilization counteracts images that seem to float on the CCD by using internal circuitry to interpret video after the image has been captured. The optical option uses the len’s mechanism to compensate for external movements.

Sound is also an important consideration. Sound relies on the quality of the microphone on the camcorder. Some camcorders offer zoom microphones which enhance the voice quality of the subject being recorded. If sound is important to your recordings consider a camcorder that has a socket to plug in a remote microphone.

Do you need to film at night or in dark situations? Then you need to consider the night mode abilities of your camcorder. Many camcorders offer the ability to film at night with the help of infrared or a special slow shutte mode that effectively utilizes ambient lighting. Some models provide both modes for capturing night videos.

Do plenty of research both online and by visiting your local dealers to get a closer look at the merchandise. Determine your needs in a digital camcorder and shop to get the best deal. If you get the right camcorder you will enjoy it and your movies for many years to come.

Arthur Raise asked:


Buying a camcorder can be a puzzle. When you log on to the internet and access any online sites that sell or showcase camcorders you will find your mind boggled by the number of models and features. The website www.comcorderinfo.com is impressive but for a newbie to camcorders many technical aspects and so on can create problems.

When you decide to buy a camcorder you need more than money and excitement. You need to be able to ask questions that will clear the confusion and help you choose the right camcorder for you and not be pushed into buying a model the online store or retail store is pushing.

Here are a few questions you can ask:

1. Find out where the camcorder recordings are stored. The most common media is a minidv, or tiny cassettes that record the highest resolutions. There is little or no compression so the recording is crystal clear. The other options are DVDs, flash media cards, and memory sticks.

2. Ask about the battery power and life. Most camcorders have battery power for about an hour of recording. Find out whether you have other options. Buy a back up battery and take it along with you.

3. Ask about whether the camcorder has manual controls as an option. There may be instances when you would like to set the exposure and so on.

4. Be sure to determine whether there is an “auto” mode. Ask the sales person to demonstrate. Discover for yourself whether you are happy operating the camcorder in auto as well as manual modes.

5. Most camcorders have at least two ports to transfer data to your computer. Be sure to ask questions and ask about connectivity cables too.

6. Never go by what the sales person recommends ask about the higher model and lower model. Very often although there is a considerable price variation there is little or no difference between functions.

7. Never forget to ask about accessories and models by other manufacturers. Keep your eyes and ears open for tips.

8. Find out about guarantees and return policy. This will protect your interests.

9. Ask what the difference between brands and models are. Determine the pros and cons of at least three options.

10. Since a camcorder is expensive ask about shipping as well as transit insurance.

Camcorders are expensive and it is important for you to ensure that the gizmo is worth the money you are paying. So, be sure to formulate a list of questions you want answers to. Be a wise shopper and comparison shop you need to compare not just prices but features too!

Computer Access from Cell Phones

The days of lugging around a large, weighted cell phone are gone. Today’s cell phones are slim, sleek and functional. Smartphones take that a step further and incorporate data management and computer use with cell phone technology. The idea has been well received and people are using smartphones for business and personal use.

The iphone is Apple’s latest and highly popular version of the smartphone. Other brands include Blackberry, Windows Mobile, Symbian, HTC Excalibur and Palm. These smartphones run on operating system (OS) software that allows them to share information from a computer or other interfaces. Such operating systems make it possible for users to access their computer files, graphics, history, memory, stage and more from their cell phones.

Common Operating Systems for Smartphones

1. Linux is one of the oldest operating systems in use and it is completely free. This system was created by a hobbyist and wasn’t taken seriously for many years, but it is still around and considered one of the best shareware programs.

2. Mac OSX is Apple’s version of a graphic operating system. It is a high-functioning program that turns a regular cell phone into a high-tech smartphone.

3. Solaris is Microsystem’s platform supported by Dell, HP and IBM. It is a trusted name in computers and smartphones. It works on a variety of interfaces to meet the growing demand for mobile PC usage.

4. Palm OS is based on the PDAs that hit the market in 1996. It is exceptional at keeping information organized and makes file management and storage a breeze. It is easy to use, has high graphic resolution, and uses a touch- screen model.

5. Microsoft Windows is probably the most recognized of the OS software programs. It makes Internet use on-the-go a reality.

Will Smartphones Replace Laptops or Home Computers?

Smartphones are high-end technical gadgets that are convenient because they combine cell phone features with organization and Internet access. New versions with improved features and greater capacity continue to emerge. Smartphones probably won’t replace laptops or home computers, though. As intelligent and sophisticated as smartphones are, they are not practical for long-term use. Smartphones are great supplemental tools for business, home office and entertainment purposes. But try spending eight hours in front of a tiny screen, reading, texting, copying or any other tasks you would normally do on your computer. It would not be a pleasant experience.

The Future of Smartphones

The future of smartphones is promising. We can look forward to increased battery power, larger memory capacity, the ability to watch TV and movies on the phone and the ability to be connected anytime, anywhere. Aside from better functionality, smartphones will be available in a variety of versions to appeal to a wider audience. As the competition for smartphones increases, the prices are dropping and they are becoming more accessible to everyone.

John Darby asked:


Photography is an interesting hobby. It eases your mind and soul and brings out the creative instinct in you. But this art gets more and more interesting when done with the use of a digital camera. It also introduces one into the world of digital photography. Here age, sex or skill does not matter. There was a time when people hesitated to get into the hobby of digital photography, the basic problem being the investment, but now, the time has changed and people have seriously started Digital Photography as their hobby. Do you like to be one such person?

All that matters is your passion for the art of digital photography.

Process of Digital Photography

The process of Digital Photography is a chain that starts from the shooting of images and ends with the display of the photographs. In the digital world, it is the image that forms the key element. And the picture quality of the image is determined by its resolution. The resolution in turn is the number of horizontal and vertical pixels on an image. Therefore resolution is the key factor that decides how big you can print your image or how much of it can be cropped.

Steps involved in Digital Photography

In order to understand how the digital camera suitably fits into the system of Digital Photography it is necessary to understand the steps involved in making digital photographs.

First Step: Input of Images

The input device in a computer is probably the keyboard. However, in Digital Photography the input devices are those that capture the images.

Digital Still Camera – It shoots images in a digital format.

Digital Video camera – It can capture images like a digital still camera.

Video cameras – It captures images onto a video format.

Second Step: Processing the Digital Photograph

Digital photographs can be stored onto your PC after they are taken. They can be then edited using in whatever way you want using the photo-editing program, Adobe Photoshop. Here the options are endless.

Few ways by which you can process your images

1.Crop parts of the image that you feel unnecessary and highlight the main frame.

2.If you wish to post the photos on the Web then trim down the number of pixels in the image so as to make it smaller.

3.Use filters to give the images the look of an oil painting, watercolor or the look of your desire.

4.You can stitch-up multiple frames in a single frame to create a landscape effect.

5.For a 3D stereo effect or an animated image merge two images and you can display this on the Web.

6.To improve the images make slight alterations in brightness and contrast.

7.Mish mash the images to create a photo medley.

Third Step: The final output, the Photograph

In Digital Photography there are many ways through which you can display and share the photographs you have taken.

Some of the well-known ways are as follows

1.Just e-mail the digital photographs to your friends or to family members.

2.Post the digital photos to the Web Service that will allow printing the digital photographs on T-shirts, mouse pads, posters and even on cakes.

3.Add the digital photographs to a word processing program or to the desktop of your PC so as to publish it as a document.

4.Mail the digital photographs on a Website or onto a Photo network.
