- 1). Compare the megapixels of a few similarly priced cameras. On larger cameras with big sensors -- like in a digital single lens reflex camera, for example -- the number of megapixels isn't as important as on a point-and-shoot camera. But since point-and-shoot cameras all have virtually the same sensor format, the amount of pixels comes into play. When you take pictures on a compact camera with a 7-megapixel sensor, you should be able to blow up your images (in print) to about 20 by 15 inches without distortion. A 14-megapixel camera creates poster-sized prints without distortion, since twice as many pixels are packed into the same area.
- 2). Compare the shutter speeds of the cameras and aperture values of their lenses. Even if you want an easy-to-use camera and plan to shoot only on "Auto" mode, a fast shutter speed and a good lens will save you a lot of aggravation, especially when shooting indoors at a birthday party or outside in poor light. Your compact camera will manage the shutter speed for you, but cameras with faster shutters -- in the 1/2000 or 1/4000 of a second range -- will respond more quickly. Likewise, cameras with a wider aperture will take pictures more quickly in low light. Aperture is measure in an "f/" value, and the lower the number, such as "f/3.3" or "f/2.8," the wider the aperture. This allows more light to reach the sensor, and allows the camera to use a faster shutter. For indoor photos without a flash, look for a quick shutter and wide aperture.
- 3). Compare the HD capabilities of the movie mode. Most entry-level point-and-shoot cameras have at least a 720p video recording mode; 1080p is better, but tends to come with a premium price tag.
- 4). Compare styles. Point-and-shoot cameras are half substance, half style. Many companies make compact cameras in a dozen or so vibrant colors, and to many people the color of the camera matters as much as the guts. However, consider the style only after you've evaluated other aspects first, since having a beautiful fuchsia camera, for example, won't impress anyone if you can't take a clear picture with it.
