The advice on the website is pretty good, to say the least…straight-forward and to the point. There are seven tips here. Please review them as you get set to take your first set of photos.

MEGAPIXELS

What is a megapixel?

Digital cameras capture images as pixel elements, known as pixels. Simply put, a megapixel is equal to one million pixels.

Digital images are made up of thousands of these tiny, tile-like picture elements. The more pixels, the higher the image resolution.

Resolution relates primarily to print size and the amount of detail an image has when viewed on a computer monitor at 100%.

Elements of picture quality
The number of megapixels is only one aspect relating to the quality of a camera, or the actual quality of a photo it is capable of producing. Factors such as camera sensor and the optical quality of a lens play equally important roles.

Besides the sensor and lens, other elements determine the quality of photos and prints. They include:

■Good lighting of a subject
■Proper focus
■Image clarity (lack of blur due to camera shake or incorrect shutter speed)
■Shooting at the highest resolution and quality camera setting

If you buy a digital camera with too few megapixels for your printing and editing needs, resulting prints will become degraded. A photo made into a large sized print from a camera with a low megapixel count will look fuzzy, or pixelated. So will a digital image that is cropped too much.

Viewing images at 100%
A mistake many people make it judging the quality of an image when viewing it at 100% on a computer monitor. The image will not appear tack sharp. However, when reduced in size for displaying online or printing, a quality image will look just fine.

Determining the number of megapixels
Deciding the number of megapixels you need does not have to be confusing. Don’t let a salesperson push you to buy a digital camera simply because of its high megapixel count. Besides, buying a camera with an average megapixel count can save you money.

Before purchasing, keep the following in mind:

■the maximum print size you plan to make
■if you do a significant amount of cropping when editing
Minimum megapixels for quality prints:*
Max Print Size Minimum MP Resolution
4 x 6″ 2 megapixels 1600 x 1200
5 x 7″ 3 megapixels 2048 x 1536
8 x1 0″ 5 megapixels 2560 x 1920
11 x 14″ 6 megapixels 2816 x 2112
16 x 20″ 8+ megapixels 3264 x 2468

* Unless you buy a used digital camera, it’s near impossible to find one today with a megapixel count of under five or six megapixels.
