What does megapixels mean for digital cameras and what should I look for when purchasing a camera?

We will use the camera for vacations, parties etc.

All of the major brands are good. Choose a brand that appeals to you. Then you have to think about getting a spare battery, what size memory card, if you want an extended warranty, how much you can afford, what size zoom, if you want manual controls, the size of the camera, finding a reliable place to purchase it, and the list goes on and on and on.......

The first thing to realize is that almost any digital camera will take good pictures. If more people would read the manual more than once, they would be able to take better pictures. Usually, the person assumes it is the camera when it could be them not knowing exactly what to do. Just give yourself more photographic knowledge by doing more reading on the internet.

I really believe buying a camera is an individual choice.
The person needs to read alot of reviews on cameras so they can decide on the features that they really want and need.
Go to the store and hold them so you can see if they feel comfortable in your hands. If possible, take some pictures in the store to check the quality of the pictures.
I can only give a suggestion of what to look for in a new digital camera.
Good Luck

  1. the more mega pixels the better mega pixels are the number of pixels in a picture there are 1 million pixels. pixels "picture element" or a single point in a graphic image. You want a good optic zoom in your camera because digital zoom enlarges the pixels and can make the image blurry like when your looking at a small image and keep enlarging it. Personally I like fujifilm and Canon (canons are more user friendly!)

  2. Megapixels is a measure of how big the photo will be on your computer screen, which roughly correlates with how big you will (theoretically) be able to print your images if you want big prints.

    Knowing this, manufacturers cram as many megapixels onto the sensors as they can, since they hope to fool consumers into thinking that more megapixels = better camera.

    In point of fact, too many megapixels on the sensor, and the sensor becomes less efficient. In other words, for a given physical size of sensor, there's an optimal number.

    So what is a megapixel? A megapixel is 1 million picture elements (pixel = abbreviation of picture element). So 7 megapixels = 7 million picture elements. You can think of a picture element as a tiny dot in the photo. In a perfect world, more dots=more resolution. In the real world, too many dots can introduce electrical noise into the image and/or introduce interference with the lens reducing sharpness (diffraction).

    So, what should you get? Here's my suggestions:
    1) Look for a digital camera with 7 or 8 megapixels. There's a few good 12 megapixel cameras, but 7 or 8 is all you need at any reasonable print size. Above that, and you begin to introduce the negative issues--noise, less low light sensitivity, etc.

    2) an optical zoom of 3x or better. Ignore anything referring to "digital zoom" which just is a sensor crop and not a real zoom. You can find optical zooms of 3x, 4x, 6x, even 18x. However, the more zoom you get, the less likely you'll get quality at the extreme ranges of the zoom.

    3) image stabilization. In my opinion, this is a must. Helps to reduce blur in low light, by keeping the sensor steady. Improves the number of "keepers."

    4) screen size: at least 2.5". Makes it easier to see to compose.

    5) use SD memory. There's other types out there, but SD is the most common and best choice, especially over proprietary types like the Sony Memory Stick.

    A specific recommendation: For the price, the best camera is the Canon A570 IS, which is: 7mp, 4x zoom, optical stabilization, and facial recognition (camera recognizes faces and focuses on them!). About $ 155.

  3. The more megapixels you have, the bigger picture you can print or display on your computer screen. But if you are just printing the standard size pictures and not doing anything else with the photos. Then 4 or 5 megapixels is more than enough for your needs.

    The thing to look for in a digital camera is face recognition and image stabilization technology. This is what will allow you to take great pictures at parties in low light conditions. Without the image stabilization technology, the digital camera will make grainy and smeary pictures in low light conditions that normally exist during evening parties.

    Canon PowerShot A720 IS is an example of a good camera for your purposes. And you can probably buy it for around $ 250.

    Here is a review of this camera:

  4. It's a measure of the amount of image detail captured by the camera.

    The most you'll need is 8.

    With point-and-shoot cameras, anything over 8mpx will start to seriously degrade low-light performance.

    Cameras with larger sensors (like DSLRs) will make better images, even with fewer megapixels.

    Hope this helps.

  5. Anthony is right. My compact digital camera has very good performance in low light BECAUSE it "only" has 6MP and has a larger sensor than most other compact digital cameras. If I were you, I'd shop by sensor size, not megapixels.
