The Top 10 Things You Need to Know

1) Resolution is less important than you think

There is a popular misconception that more megapixels lead to better pictures. This is not the case.

Sure, higher resolution gives you the ability to crop more aggressively or print large pictures, but only a fraction of digital photographers will benefit from this ability. If you're a casual shooter who won't be printing pictures larger than 8x10" or doing extensive computer editing, then a camera with 5- or 6-megapixel resolution will be sufficient.

More advanced photographers will likely appreciate the flexibility of higher resolution, but a 10+ megapixel camera is by no means necessary to create stunning pictures. Choose a camera you can understand and afford, and don't be fooled by glitzy high-resolution specs.

2) Zoom is more important than you think

Whether you're shooting distant wildlife or close-up portraits, you can never have too much zoom. The majority of digital cameras have 3-, or 4x optical zoom, but you will never regret choosing a model with more telephoto power.

Fortunately the extended zoom camera category is growing rapidly, and there is a great selection of models with 8-, 10-, or even 12x optical zoom. For the ultimate in zoom control and quality, look for an extended-zoom camera with image stabilization, which will ensure that shots taken at full telephoto will be tack-sharp, even without a tripod.

3) Travelers should use cameras with AA Batteries

Digital cameras come in two varieties: those that use AA-size batteries and those that are powered by proprietary lithium-ion batteries. If you are a traveler, particularly someone who enjoys remote or rustic locations, choose a camera with AA batteries.

When a camera that uses proprietary batteries runs out of power, you have no choice but to plug the battery into a power outlet to recharge it. This requires an available outlet, a battery charger, and, if you're in a foreign country, a power converter. If access to an outlet is ever in doubt, or if you don't want the hassle of carrying cords and chargers, then the limitations of this system are obvious.

When a camera that uses AA-size batteries runs out of power on a trip, you can simply throw out the old batteries and drop in a new set of high-performance AAs like the Energizer E2 Lithium line. Two or three sets of such batteries can usually take you through a 10-day trip. If you're out of high-performance batteries, you also have the option of using standard alkaline batteries, which are available anywhere in the world, and make a cheap and convenient source of backup power (though they only offer a fraction of the life of high performance batteries).

Recent trips to Asia and Africa have borne this theory out—after my companions' cameras had been sidelined by dead batteries, I was still happily shooting away with my AA-powered Canon PowerShot.

4) Small cameras get shots that big cameras don't

Sure, that big, black SLR with the long lens may look fancy, but it won't do you any good if you're not carrying it. Never underestimate the importance of having a camera that is small enough to fit into your pocket—you'll be amazed at the spontaneous pictures you'll have the opportunity to take. While the photo quality produced by an ultra-compact does not equal that of a large SLR, the ability to whip it out and snap a shot while others are fumbling for their bulky cameras more than outweighs this drawback.

5) Canon makes great cameras

Canon digital cameras receive consistently great reviews, and for good reason: Over the last 2+ years, Canon has time and again proven itself capable of producing well-designed cameras that produce impressive results. From the EOS line of digital SLRs to the diminutive PowerShot ELPHs, Canon invests substantial time in the design process, and the results pay off—photographers of all abilities rave about their Canon cameras.

There have been some mistakes along the way—the Canon A70 was built with a design flaw that produces crippling error messages and black lines on the LCD, but newer models seem to be free of this problem. If you're looking for a great combination of features, price, and performance, Canon will almost always deliver. (NOTE: Digital Camera HQ is in no way affiliated with Canon, nor do we derive any benefit from recommending one brand over another).

6) Kodak makes great, easy-to-use cameras

When I bought my mother her first digital camera, I chose a Kodak, having read countless reviews that raved about their user-friendly controls. The reviews were right—Kodak's EasyShare digital cameras are remarkably easy to use: the menus are simple, the LCD text large and clear, and the controls largely self-explanatory. The results are just as impressive, with attractive, saturated colors and crisp definition. Don't be fooled into thinking that Kodak digital cameras are just for beginners, however—their simplicity aside, many of the high-end EasyShare models offer a full suite of manual controls for ambitious photographers.

7) Digital cameras can and will break

Whether it's due to accidental damage or simple wear and tear, digital cameras are not as durable as their film counterparts. Many photographers have film cameras that are ten or twenty years old—don't expect this kind of longevity from your new digital toy. Some cameras suffer from design flaws (like black lines on the LCD screen of the Canon A70), while others fall victim to the kind of mechanical breakdowns that effect every kind of electronic gear.

Does this mean that you shouldn't buy a digital camera? Absolutely not. A digital camera will so fundamentally change the way you think about photography that you will wonder how you ever got along without one. You must, however, be comfortable with the fact that one day your camera will cease to work.

For some, this knowledge may keep them from spending top dollar on a fancy camera; others simply accept it as the sole downside of working with digital. The most important thing is to do your homework before you buy—any fundamental design flaws will be quickly apparent in user reviews.

8) Don't put all your pictures on one card

After returning from a trip to Asia, I eagerly inserted one of my memory cards into a card reader to download my new pictures. For still unexplained reasons (likely a static electricity discharge), a card that should have held over 200 pictures was suddenly rendered blank. Two weeks and $250 later (thanks to www.drivesavers.com), I had recovered about 90% of my pictures, but the rest were lost permanently.

The moral of the story? Like any other technology, flash memory is not flawless. It is very rare to lose images, but it does happen, and the fact that I had spread my pictures between 5 memory cards protected me from the possibility of losing two weeks' worth of irreplaceable vacation memories. Given the choice between choosing a single 1GB memory card, or four 256MB cards, I will always choose multiple cards.

9) Find & use a simple photo editing program

Most digital photographers will never take the time to master expensive and powerful photo editing programs like Adobe Photoshop or Jasc Paint Shop Pro—these programs are too complex and time-consuming for all but the most dedicated photographers. Fortunately there are a variety of easy-to-use editing programs that even novice photographers can use to edit, improve, and organize their digital photos.

My favorite program is Picasa, and it is absolutely free at www.picasa.com. With Picasa you can perform all the basic editing tasks like sharpening, contrast correction, cropping, and straightening—most with just the touch of a button. Spend a few minutes on your best photographs and you will be amazed at the results. Picasa also make it incredibly easy to organize your best shots so you don't have to sift through hundreds of unwanted pictures to find your prizewinners.

10) Print and display your pictures

Far too many people take great digital images, only to have them languish in obscurity on their hard drive, never to be enjoyed by others. Don't let this happen to you.

Online image hosting and printing companies like Snapfish or Kodak Gallery can turn your digital images into high-quality prints of any size. You can simply upload your pictures onto the website. From there you can order prints of every size as well as photo mouse pads, calendars, t-shirts and other gifts. You can also send a link to friends so that they can view your pictures online and order their own copies.

If you want to see more of your own pictures, nothing beats using them as a screen saver on your computer. Simply right-click on your desktop, choose Properties/Screen Saver/Settings, and you can direct your computer to the pictures you wish to use. Set the screensaver to change images every 10 seconds and you'll have an instant slide show every time your computer is idle.

Tips Buying Digital Cameras

1. Set a Budget Before Buying

Before deciding on purchasing a digital camera, it is important that you set yourself a budget before going online or visiting an electronics shop. Like purchasing any other big-ticket item else such as a computer, car, or house, there are tons and tons of options, and you don't want to get stuck with more camera than you can afford. Yes, the high-end cameras offer the best zoom, more megapixels (which don't always mean better photos!), and the added features, but they can also take a huge bite out of your wallet if you are not careful. When starting out in the world of digital photography, I would recommend not spending a huge amount of money on the high-end prosumer or digital SLR cameras. Look for cheaper, yet powerful, compact digital cameras that are easy to hold and don't add too much weight when you travel. Learn the basics with this digital camera and make sure you enjoy the hobby before spending the cash for higher-end digital cameras. If you're afraid that you will be stuck with several digital cameras by buying less-expensive ones and later upgrading, note that there are many uses for your old digital cameras

2. Ignore Digital Zoom

Although many salespeople would disagree, when choosing a digital camera to purchase, I would completely ignore advertised digital zoom magnifications and only look at cameras' optical zooms. Digital zooming performs an interpolation, or computer-based 'guesswork', of an image to try to increase the perceived zoom distance. These can result in "fuzzy" images or those with less than optimal clarity, especially if you blow them up into 8x10 or larger photos. However, optical zoom provides for a true zoom-in or zoom-out on your subject. If you want an example of what a photograph may look like when taken with a digital zoom, take a photograph into a piece of photo-editing software and increase its size by 100% or 200%. Although the picture will look bigger on screen, you will start to see dots or imperfections in the image. That's what happens with digital zoom. Higher optical zoom cameras can allow you to take a greater variety of pictures, but they do tend to cost more money, which is why lower-priced cameras tend to advertise their digital zoom capabilities a lot more. However, for many photographers, the enhanced image quality is well worth the higher price.

3. Two Considerations when Buying a New Camera

Planning on buying a new digital camera? Among the many choices you have to make including megapixels image quality, and zoom capability, here are two more things you should consider. Media Type: There are lots of media types available for cameras, such as CompactFlash, SecureMedia, etc. Because of my previous purchases of CompactFlash cards that I used in older cameras, if upgrading, I would not want to purchase a camera that used a different type of memory unless its other features far outweighed those of competing cameras. Memory prices are going down, but cards are still not cheap and I don't want to 'throw away' this media investment when upgrading. Some cameras are realizing that not everyone wants to use their manufacturer's proprietary media format. For example, the upcoming (at the time of this tip's writing) Sony Cyber-shot DSC-F828 uses Sony's Memory Stick format, but this digital camera also supports CompactFlash and MicroDrives. Battery Type: If you currently use rechargeable batteries, factor into your purchasing decision whether or not your 'dream' camera supports the same types of batteries. I own six or seven sets of AA NiMH rechargeable batteries and would be very weary of purchasing a camera that had its own custom battery type. Of course, if the digital camera offered double the megapixels, a wider zoom lens, and better quality photos, I might reconsider (grin).

4. Small Doesn't Mean Underpowered

Purchasing a small digital camera definitely can have its advantages. They are easier to transport long distances, less bulky to carry with you on trips, and less conspicuous. Plus, nowadays don't expect all small digital cameras to be underpowered toys! Small cameras may not have as many features as digital SLRs and high-end prosumer digital cameras, but their megapixel resolutions are matching, and sometimes beating, their higher-priced alternatives! Plus, smaller cameras are starting to come with larger and larger zooms. While a high-priced large digital camera looks impressive to onlookers and usually comes with a wide variety of image manipulation features, don't overlook the value of small digital cameras. If you just want a digital camera to use for friend and family photos, travel a lot and need something that takes up less luggage room, or just don't want to deal with the bulk of a large digital camera, consider the lighter alternatives.

5. Be Careful When Buying Package Deals

It almost sounds too good to be true. A digital camera, plus memory, a tripod, a backup battery, extra lens, and more... for hundreds of dollars off the original price because it is a package deal! When buying a digital camera, you're almost sure to be overwhelmed with such "Power Buys", "Closeout Package Specials", and the like. And sometimes, these deals can be real money-savers, especially if you need another camera bag, more memory, a backup battery, etc. However, be careful before you spend your hard-earned money. While these deals may save you money, they may not save as much money as specified by the individual products' manufacturers' retail prices. And, sometimes, these deals are just ways for unscrupulous dealers to make a few extra dollars on the side, selling substandard or closeout equipment in combination lots that seem like huge bargains for the unwary. Before you buy such a package deal, examine the contents. Check out what the prices of the individual items REALLY cost, and that may mean visiting other digital camera stores or websites. Then, only then, make a decision. Do you really need the products? Does the package deal really save money, even if not as much money as the seller claims? I've saved money buying package deals when I really needed all the included equipment, but some people end up spending way more than originally intended on equipment they don't need. Don't let the latter happen to you.

6. Check What the Zoom Really Means

Be careful when reading a manufacturer's specifications on a digital camera's zoom factor.
Many digital cameras may mention that a camera has a 10x "Combined" or "Total" zoom. This *may* mean that a camera has a 5x optical zoom and a 2x digital zoom (5 X 2 = 10). As mentioned previously in MalekTips, you should only concern yourself with optical zoom as digital zoom just does a pixel interpolation when taking photos, resulting in photographs that may not be as sharp as you'd like. Read the specifications carefully, and if you have any questions, ask a camera salesman about the camera's optical zoom only.

7. Don't Expect a Camera to Come with Enough Media

When you purchase a digital camera, unless it happens to be a package deal, don't expect the camera to come with enough media to handle your photography needs. Nowadays, most digital cameras, if they come with any media at all, will only be packaged with a 16 or 32 MB card. Though that used to be enough memory for a couple dozen pictures, high megapixel photos in fine, very fine, or raw detail can eat up that memory in just one or two photos. Prepare to spend money on at least one extra media card.

8. Effective Pixels and Foveon X3

Thanks to MalekTips reader kgelner for updating some of this information.
When comparing megapixel counts between digital cameras, be careful when comparing cameras containing the Foveon X3 three-layer sensor. You may think the resulting photos will come out larger in resolution than what the camera provides. Most digital camera sensors can detect only red, blue, or green per pixel, using what is called the Bayer filter. A moire effect sometimes appears in photos as digital cameras try to accurately reproduce colors via dithering effects. To reduce the moire effects, digital cameras may use demosaicing effects that may result in "smearing" the photo, causing some loss of sharpness. Foveon X3 digital cameras, however, have a sensor array, with three sensors for each pixel - one detecting red, one blue, and one green. The digital camera then merges the results together, supposedly resulting in sharper, warmer, and more pleasing photos. Because of the extra detectors, a Foveon X3 digital camera that has, for example, 3.3 million detectors for red, green, and blue may advertise itself as being 10 megapixels (3.3 multiplied by 3 is approximately 10, though the resulting resolution of a photo will only be 3.3 megapixels). The actual quality of the photo, however, may differ depending on the digital camera's implementation, having approximately the same quality as a 5-8 megapixel photo taken with the Bayer filter.

How Much Optical Zoom is Needed?

(Note that this tip was written for users of compact, intermediate, and prosumer digital cameras. Digital SLR users can purchase lenses with different zooming capabilities.) With the plethora of digital camera choices available, one question you may ask is how much optical zoom do you really need for the types of photos you want to take? Purchasing a digital camera with a greater optical zoom distance is more expensive than one with only a 2x or 3x zoom, so this decision can greatly affect your pocketbook. While there are no hard and fast rules, consider the following suggestions. Realize that even if you need a lesser zoom for most of your photos, there will always be times where a greater zoom may be useful.

* Are you primarily taking photos of friends and family, such as in parties or social situations? If so, a 2x or 3x zoom should be plenty. Just be sure to get up close if you need to record detail of a situation.

* Looking for photos of outdoor scenery, or interested in taking photos of architectural elements in a cityscape? A 5x+ zoom can help you take pictures from further away without sacrificing detail.

* Interested in taking photos of wildlife where you need to stand back to avoid scaring animals away, at sporting events where you may be situated in third level seating, from atop observation decks in large metropolises, or other situations where it will be difficult to get in close to your subject? That 7x+ zoom may be needed to get the photos you want
