Information of Camera

When you're shopping for a point and shoot digital camera, you want to make a checklist of the major features that will help you decide which camera to buy. In this article we discuss resolution and how it is important to choose the right resolution camera depending on what you plan to do with your photos.

The resolution of a digital camera is usually measured in megapixels. This number represents the total number of pixels per photo the camera is capable of producing. The more megapixels means greater resolution.  Although you may not need a really high resolution, it can come in handy when you want to crop your photos to make for a better looking photo. So what resolution should you get?

If you stick to the standard size for most images, which is 4x6, you don't need a high resolution camera. A camera with resolution as low as 2 megapixels will work for decent 4x6 photos. These days, that may be the resolution of your camera phone.

If you rarely make 8x10 prints from your photos, a 6 megapixel camera is probably adequate for your needs. But if you plan on making larger pictures, for example 11x17 or 13x19 you should think about a camera with more megapixels. Consider a camera that has 10, 12 or more megapixels available. Who would need such large pictures?

Many wide-format inkjet printers support images this large. Also many people bind their pictures into custom photo books which they keep or give as gifts.  You will want your pictures to be in sharp focus if you are going to put them into an expensive custom made book.

One advantage of the larger megapixel cameras is that you can always set the image capture to a lower resolution. This comes in handy if your memory card is almost full and you want to get a few more pictures before your vacation is over.
