How to Master Digital Photography

Digital Cameras
The price of digital cameras has considerably reduced and they are quickly replacing conventional cameras in the market, with all its technology and portability, the digital camera is the future of cameras.


Basically a digital camera is a device used to capture pictures without the use of films. Unlike the conventional camera, the digital camera does not rely on mechanical and chemical processes.

The images captured by digital cameras are in electronic form in a language that is easily recognized by computers. The language is known as pixels;

In order for you to understand pixels, let me explain how digital photos are created;
Digital cameras use a special sensor which is known as CCD to capture photos. The sensor comprises of many tiny light sensitive sensors each representing a pixel. The number of pixels can also be referred to as Mega-Pixels;

A mega pixel is equivalent to one million pixels. The resolution of your image is based upon the mega pixel property of your camera, the higher the resolution, the more you will be able to enlarge your picture without the grainy or the out-of-focus effect that we all want to avoid
When you take a photo the shutter opens and light hits the sensor, each tiny sensor captures the light intensity and color and in turn creates pixels that make up a photo.
When you look at a photo, if the pixels are small enough the photos look crisp and has a 'high resolution'. If the pixels are too big you will get that “out-of-focus effect”
A general rule of thumb though is to always make sure your photos are at 150PPI or higher.

Here are some tips of things to look for when shopping for the best digital camera.

• Mega-pixels.

One of the most important features of a digital camera is the amount of mega pixels. Higher mega pixels = Better quality photos.

• LCD Size.

A 1.5-inch display is average, a 2-inch LCD display is good, but the best LCD size would be 2.5 inches or higher

• Zoom.

Most digital cameras have both digital and optical zoom. Digital cameras usually have an optical of between 3x to 10x. A higher optical zoom is always better than a higher digital zoom.

• Computer Interface.

Always make sure that it is compatible with your PC, laptop, palmtop or whatever your local picture printer software is.

If you are going to be carrying it everywhere, choose one that’s handy and portable.
