Digital Camera: a Buyers’ Guide

A digital camera takes still photographs or videos or both by recording the images on a light-sensitive sensor digitally. Most compact digital still cameras can record moving video and sound as well, apart from still photographs. The sales and popularity of digital cameras have increased now compared to the 35mm film cameras.

Digital cameras have a feature for viewing the image that is recorded immediately on the Camera display screen, the feature that is not available in film cameras. Other features include such as the facility to capture a lot of images on a small memory chip, record video along with sound, edit the images, delete the images not required etc. Digital cameras are now available along with many devices ranging from mobile phones and PDAs to vehicles.

The camera perhaps has been affected more by the digital technology than any other products. The digital cameras are not a new phenomenon. The first digital camera was released by Kodak in the U.S. market around 15 years ago. The DCS-100 model at that time with 1.3-mega pixels was available for about $13,000. The digital cameras have emerged with more features and are available at comparatively lesser prices, even to the extent of $80 at select stores.

The biggest benefit of Digital camera technology is the storage capability. You can view the photos on the camera itself, on a web page, a computer monitor, or on paper after printing. The digital camera can be connected to the printer directly through the USB port for printing pictures. People can afford to buy a digital camera today as the prices have fallen with the availability of more features.

It is important for you to know the issues of image resolution for comparing digital camera models. The unit of graphical representation used for displaying digital data by Digital cameras is called Mega Pixel (MP). More the mega pixels, the higher the resolution of the final image. Still you need to compare digital camera images recorded with your actual requirements.

Some typical resolutions found on Digital cameras are:

256×256 – This is available with very cheap cameras. Picture quality is unacceptable.
640×480 – Suitable for posting pictures over a web site or for sending pictures by email.
1216×912 – This resolution is good for printing pictures.
1600×1200 – This is a High resolution standard with around 2 million total pixels.
2240×1680 – This is available on most 4 mega pixel cameras.
4064×2704 – This is available on high-end digital camera with 11.1 mega pixels.

Some High-end consumer cameras can record pictures of over 12 million pixels. Most professional cameras have 16 million pixels. Large format cameras have 20 million pixels. For comparison sake, it is stated that the quality of 35mm film is approximately around 20 million pixels. Some types of Digital cameras are Point and Shoot, Semi-Professional, Bridge and SLR.

You need to know the complete package offered when you compare the prices of digital cameras. You can look for the availability of image-editing software, carry case, add-on Memory card and USB cable for working on your computer, when you want to compare the prices and the features offered. Other general features that you can look into are the availability of an LCD screen, a timer, a built-in flash, a date & time stamp, optical zoom feature and optical zoom lenses of good quality.

Can anyone recommend a good online guide for SLR photography?


I have a fairly basic SLR camera. Not digital though. Does that matter? I inherited the camera and don’t have the manual. I want to learn more about the camera and photography in general – does anyone know a good starting point?

Good for you.
The SLR will teach you everything you need to know, regardless of how basic it is.
Focusing, depth of field, framing the shot, lighting – it all comes as part of using this piece of kit.
If you want to go digital later, you’ll be fine as it’s probably easier.
You DO get digi SLR’s though.

Get out there and shoot anything and everything.
Maybe do small stuff – anybody can do a landscape.
Try detail like a porthole on a boat or coiled up rope, the little things that make the big picture.
Try keeping a note of your speeds and aperture settings so when you look at the prints you can see how you got that result, good or bad.

I did all this as a kid and now I have a film company that does OK.
All because I shot as much as my pocket-money would allow (and a little bit more – thanks Mum!).
