10 tips for buying a digital camera

How to select the right resolution & compression?

Resolution is the measurement of an image in pixels. Since the maximum available resolution of an image is only getting higher, digital cameras use a process known as "Compression" to reduce the size of the image to a manageable size before it is stored. While this dramatically increases the amount of pictures you can store on each memory card, there is a trade off in quality.

Note:

• Low Resolution (800 x 600 pixels), Medium Resolution (800x600-1280x1024 pixels), High Resolution (Above 1280 x 1024 pixels)

• Compression mode yields progressively higher image quality as one switches from "Normal" and "Fine" to the Superfine Mode.

What is the storage capacity of the digital camera?

Digital Cameras store images in removable storage media such as compact flash card. The storage capacity depends on the memory space of the compact flash card , for instance, 32MB can store more images than an 8 MB compact flash card. Typical storage for a still camera is 2 GB at the minimum. Another thing is the speed of the memory. If the memory used is of low speed, it will take more time to save images. The instrument will be ready only after few minutes for a second shot. So while selecting the camera, check the response time of the camera memory. Eg : Olympus xD picture card.

However, the amount of images a storage media can keep varies with the CCD size in a digital camera. It also depends on the resolution and the compression of the picture.

How to take care of your lenses?

Dirt, dust and fingerprints impact the performance of your lens. And believe it or not, there is a right way and a wrong way to clean a lens. Do it right and you’ll maintain peak optical performance. Do it wrong and you could scratch an expensive piece of photographic equipment.

Carefully blow off any dust or dirt, using a blower brush or (very carefully!) compressed air.
Place a drop of lens cleaning fluid on a clean piece of lens cleaning tissue, or blow gently on the lens so that moisture condenses on its surface. Gently wipe the lens surface from the edges toward the center of the lens, with a lifting rather than rubbing action. A micro-fiber cleaning cloth is a good alternative to lens tissue, and requires no lens cleaning fluid.

Eg : Canon Lens Cleaning Kit.

What can you do with the images you have taken?

a. Store it in your PC - Digital cameras comes with a USB cable for connection to PC. A .jpeg file is the most common way to send images because they are "compressed" and load faster.

b. Send it to your friends via email - Make sure your recipient uses an e-mail program (like Microsoft Outlook) that allows him or her to view attachments. Then scan your "best" photos. Limit your attachments to 1 or 2-they will load faster.

c. Store pictures in online PC-based albums There are many online photo albums, some offer free storage, while others charge for rental space. Check out these sites:

• Yahoo
• photopoint.com
• BizHat.com
