A megapixel is a unit of measurement equaling million pixels. Pixels are the tiny dots that make up a digital image. The more megapixels a camera has will result in a better quality and detailed photo.
The amount of megapixels will determine the ideal print size. The higher the megapixel the larger you can print and closer you can crop. Below are examples of ideal print sizes:
- 4 MP = 8 x 10"
- 5 MP = 11 x 14"
- 6 MP = 16 x 20"
- 8 MP = 20 x 30"
Digital cameras may include an optical zoom lens, optical and digital zoom settings, or a digital zoom only.What is optical zoom
Optical zoom lenses physically extend to magnify your subject. A motor controls the lens movement. When you press the switch to "W" or "T," the subject is either magnified or reduced in size. The "W" stands for "wide-angle" (reduce). The "T" stands for "telephoto" (magnify). What is digital zoom?
Digital zoom crops your image and magnifies the result of the cropping. This magnification process is called interpolation. To make the cropped area bigger, digital zoom makes up, or interpolates, pixels to add to the image, which may give less than satisfactory results.
