Digital Photography

How do I tell if a camera is a good one?

Generally speaking if you stick with the name brands that have traditionally made cameras you will be safe. Canon, Nikon, Pentax, Minolta, Kodak, and Fuji all have nice models. I would recommend checking the consumer magazines, manufacturers' web sites, and product reviews for more information.

What is a mega pixel and why does it keep calling me?

First you need to know what a pixel is… A pixel is the smallest unit of a digital image or sensor. If you've ever put your eye up to a computer monitor or TV screen, you've probably noticed the image is made up of tiny little dots –those are pixels. A mega pixel is 1 million pixels. I don't know why they keep calling you.

How many mega pixels do I need?

Anything over 3 mega pixels will give you the resolution of 35mm film when printed at 8 x 10 inches.

What do I do with the pictures once they're in the camera?

Once the images are in the camera they are stored on a memory card. You will need to transfer these images to your computer's hard drive or you can take the card to many camera shops for printing. Check your camera's owner's manual for instructions on transferring the files from the camera to the computer. You may also want to invest in a card reader for your PC. They are inexpensive and easy to use. Instead of plugging your camera into your PC every time you need to transfer, you simply eject the memory card from your camera and insert it in the card reader.

How do I get real pictures made?

There are many reasonably priced high-quality photo printers available today. You could print your images on one of these printers. Another option is to transfer files via the web to a service bureau or take a disk or memory card to the local Wal-Mart or camera shop for printing.

Where can I get tips on buying/using a digital camera?

Consumer magazines frequently have reviews and recommendations or you can check the web. Some good sites are:

Another option is to use a digital image frame. You can plug a memory card into this type of frame and display images that way. Many new TV sets also have memory card slots and will also display images.

It's hard to imagine that hundreds of your photographs could be contained in a camera that is the size of the palm of your hand. Since we covered the use and science of digital cameras in a previous issue here were going to ask Joe what are the best ways to get your pictures from 1's and 0's inside your digital camera to actual prints.

Digital photographs give you loads of options for their processing and display.
