Buying a digital camera with features you want can be just as important as how many megapixels it has. Yes, it’s true!
Don’t get caught up in advertising hype that leads many to believe that more megapixels is always better, particularly when buying a compact digital camera with a small sensor.
Megapixels, printing and cropping
Two factors come into play when deciding about megapixels: print size and the amount of cropping you do.
The more megapixels, the larger size prints can be made without images becoming pixelated or jagged looking. More megapixels also allows larger areas of images to be cropped and still retail detail in prints.
Megapixels and print size
Many digital camera owners print 4×6,” the most frequently used print size, and occasionally up to 8×10.” If they crop, it is rarely more than a small percentage of an image. If you fit into this category, a camera with a resolution between six to eight megapixels should serve you well, though many digital cameras today have 10 megapixels or more.
Slightly larger prints may show signs of pixelation but only when viewed close up. If you primarily send photos by email, or use them for online auctions, a five or six megapixel camera should more than suffice.
Remember that image quality is based on several factors, not only the number of megapixels. They include:
- sensor size
- image processor
- quality of the camera lens
- proper exposure and lighting of a subject
- accurate focus of a subject
- lack of blur due to camera shake
- adequate shutter speed for the subject
