Choosing a Digital Camera: Making Sense of the Technobabble

If you're like a lot of people, you don't apperceive a megapixel from an f-stop, you just wish a camera that works able-bodied and takes nice pictures. But the ads and websites are about drowning you in computer abracadabra and abstruse numbers.
The acceptable account is that today's agenda cameras are abundant bigger than even a brace years ago, and a lot of cameras from acclaimed brands will do a appropriate job. So the pressure's off; don't anguish about your accommodation too much. Armed with just a little understanding, you'll be able to acquisition a camera that fits your needs and will not breach the bank.
Here are the things you'll wish to attending for, and how they'll affect your agenda camera experience:
1. Megapixels
I'm advertisement this one aboriginal not because it's absolutely the a lot of important, but because it's the one the camera makers harp on the most. You're traveling to see a megapixel amount in every camera ad and artefact listing, so you ability as able-bodied apperceive what it is.
In a nutshell, the amount of megapixels a camera can abduction describes the akin of detail and accurateness you will get. A 3-megapixel camera divides a photo into three actor alone dots and annal the blush of anniversary one of them. A 10-megapixel camera divides it into ten actor dots, so of advance it is recording added details.
However, it usually stops mattering afterwards about 6 megapixels. That's because this is already abundant resolution for photographic-quality 8x10" prints, which are the bigger that a lot of humans anytime make.
Having a beyond amount of megapixels than that does accord you some added abandon - for instance, you can crop allotment of your photo abroad and still accept abundant for a large, top superior print.
But if you don't anticipate you're traveling to be authoritative poster-size prints, or application photo abetment software to crop ample areas out of your images afore press them, afresh don't anguish too abundant about acutely top megapixel counts.
2. Zoom
Zoom comes in two flavors - optical and digital. It's usually bidding as a amount followed by an "x". A zoom listed as "3x", for example, can accomplish the accountable of your photo arise three times larger. That's a archetypal zoom for pocket-sized cameras, but beyond agenda cameras may accept up to 12x or more.
Optical zoom agency lenses, just like with blur cameras. The admeasurement of the angel is added by affective two lenses further afar from anniversary added in the camera. If the lenses are of acceptable quality, afresh the consistent continued angel will aswell be aciculate and clear.
Digital zoom, on the added hand, is not so useful. Application agenda zoom consistently decreases the superior of your image; no austere columnist would anytime use it. Camera manufacturers cover it because it doesn't amount them annihilation and allows them to affirmation college zoom ratios than they're accommodating to accommodate with optics.
So it's actual important to attending alone at the optical and agenda zoom numbers, and alone pay absorption to the optical zoom.
The cast ancillary of able optical zoom is that it makes the camera beyond and heavier. So you accept to adjudge how abundant added weight that 10x lens is account to you.
3. Chiral features
All customer agenda cameras action absolutely automated focus and acknowledgment control. This agency you usually don't accept to anguish about accepting your accountable acutely focused, or anticipate about the akin of ablaze at altered credibility in your attempt and how that will affect the photo.
But sometimes the camera doesn't accomplish the appropriate guess. It may accumulate absorption on the amiss thing, or it may get abashed by ablaze or aphotic areas, and the accomplished photo may appear out too ablaze or dark.
If your camera alone has automated mode, afresh you're stuck. On the added hand, if it has chiral overrides, you can acquaint it absolutely how to focus, or how ablaze to accomplish the photo. A lot of humans don't care, but if you anticipate you ability wish to be a perfectionist, afresh you should attending for a camera with chiral focus and chiral acknowledgment controls.
4. Cine mode
These days, agenda cameras don't alone yield still photos - about all of them can aswell accomplish movies. The movies usually aren't that great, and the breadth may be acutely bound (maybe even beneath than a minute), but sometimes it's nice to be able to abduction something with motion and sound.
The a lot of important things to attending for is the best breadth of the cine - the best the better, and absolute is bigger still. Be acquainted that continued movies can yield up a lot of your camera's anamnesis - afterwards all, a cine is absolutely just an abominable lot of still shots, one afterwards another. You may acquisition that afterwards demography a continued movie, you accept to move it off your camera and into your computer afore you accept abundant allowance to yield abounding photos.
You may aswell wish to analysis the resolution of the movies (this is like megapixels, explained above, except that the resolution for movies is usually abundant lower than for still photos). 320x240 is a accepted resolution, but abounding cameras are now alms 640x480 or even higher.
The endure affair to attending for is anatomy rate. 15 frames per additional (fps) is standard, but these movies tend to attending affectionate of jerky, abnormally if there's fast motion. 30 frames per additional is the aforementioned as television.
5. Awning admeasurement and quality
You'll absorb a lot of time searching at the little (or not so little) awning on the aback of your camera, so accomplish abiding it's a acceptable one. It should be large, accept a lot of pixels and be bright.
Most accepted cameras accept two-and-a-half inch screens, but beyond ones are boring acceptable added common.
The added pixels the awning has, the easier it will be for you to analysis the superior of your pictures afterwards accepting to appearance them on a computer adviser or book them out. 75,000 pixels is on the low end; 250,000 is currently about the best on the market.
The accuracy is something you can alone appraise for yourself. If you get the chance, try out the camera in a boutique during the daytime. Yield it to the window, so there is lots of accustomed light, and analysis whether you can still see the angel acutely with the sun at your back. It's arresting aggravating to use a camera if the awning is done out and dim in daylight.
6. Admeasurement and weight
Cameras accumulate accepting abate and smaller. Some of them, like the latest Exilim cameras from Casio, are abate than a backpack of cigarettes and still bear acceptable shots. But you'll pay for the privilege; the atomic cameras amount a lot added than beyond models with agnate features.
When you're cerebration about size, apparently the a lot of important beginning is whether or not you can fit it in your pocket. If you can, it's acceptable you'll acquisition yourself accustomed the camera about - and application it - abundant added than you would if it appropriate accretion a bag. But any abate than that, and you're apparently paying added just to be able to appearance off.
7. Batteries
Some agenda cameras use accepted AA or AAA batteries, like you ability use for a limited ascendancy or a carriageable CD player. These accept several advantages. Apparently the a lot of cogent one is that if you acquisition yourself absolutely out of array power, you can consistently nip into the abutting accessibility abundance and buy a new set, and be appropriate aback out demography pictures again.
Of course, it doesn't accomplish faculty to use disposable batteries all the time for these cameras. It's expensive, and bad for the environment. And they don't endure actual long: A set of rechargeable AA batteries may endure up to alert as continued in your agenda camera as the a lot of big-ticket name-brand disposables. And that's just on one allegation - you can accumulate recharging them afresh and again.
Other cameras don't accord you the choice; they use custom batteries that are distinctively advised for agenda cameras. These batteries tend to be abate and lighter than AAs or AAAs, packing added ability into a abate unit. On the added hand, they're aswell absolutely expensive. One will be included with the camera, but if you wish to get a advancement (so you can accumulate cutting photos afterwards active through a abounding charge), you may acquisition yourself ponying up $50 or more. Aforementioned affair if you accidentally lose it.
Well, that's it. It's still a lot to anticipate about, but it absolutely comes down to a few simple questions about priorities. At atomic now you apperceive how to adjudge whether all those appearance are absolutely account the added money. Acceptable luck!
