Digital photography is helping to revolutionize the way we view our pictures and the way we are able to capture the most breathtaking images.
Digital photography is becoming more affordable every year, and the technology to make fabulous photos is well within the reach of the average consumer.
Digital Photography is more than just using a digital camera; it also entails some post processing in an image editing software to the image you captured with your digital camera. Digital Photography is a process where pictures are taken to a computer disk or memory card rather than film.
Digital photography is one of the late 20th century s most innovative technologies. Digital photography is a radically different kind of photography, because the photographer can finally see what the film sees.
You waste nothing; there’s no film required, and because you only print the pictures you need, digital photography is cost effective and environmentally friendly.
First of all, the general claim about digital photography is that it makes photography easier; and that’s wrong already. And this is where it is getting interesting because, basically, the argument is that digital photography is better because you don’t have to wait. Although the resolution of digital photos is not nearly as high as photos produced from film, digital photography is ideal when you need instant, low-resolution pictures.
For many people, the biggest advantage of digital photography is that it eliminates the need for picture processing. Almost all of the cost of digital photography is capital cost, meaning that the cost is for the equipment needed to store and copy the images, and once purchased requires virtually no further expense outlay. Lastly, digital photography is the future, there’s no getting around that, and the sooner you start shooting digitally, the better equipped you’ll be to evaluate and handle new technology as it comes out. After all, digital photography is just another tool of modernization showing the advancement of photography in an ever-changing world.
The age of digital photography is here and here to stay. With more than 64 million digital cameras sold last year alone, digital photography is more popular than ever. Once of the best of the long list of advantages of digital photography is the immediate ability to view the scene through the digital cameras LCD screen.
For me, digital photography is also the greatest gift ever and the best thing since sliced bread.

Digital cameras are a vast improvement over the regular cameras. Electronic sensors are used in digital cameras to store pictures on a memory card. These pictures can be uploaded to a computer by an USB cable. Some digital cameras can record sound and video also.
It is imperative to study the different types of digital cameras, their features and identify our objective before buying a digital camera.
Types of digital cameras:
Compact digital camera – These are `snapshot` cameras invariably small and compact in size. They lack sophisticated hardware. Images are stored in JPEG format. Compact digital cameras have a sharp focus and a built-in flash.
Bridge camera – These cameras form a `bridge` between the compact digital camera and the DSLR camera. They have small sensors but large zoom ranges. Bridge cameras have an LCD electronic screen which can take a live preview of the photo before clicking it. Bridge cameras employ either electronic viewfinders (EVF) or optical viewfinders (OVF). The quality of these viewfinders is undergoing sea improvement regarding their size, resolution, visibility, magnification and refresh rate.
Digital single-lens reflex camera – An automatic mirror system is used which displays the exact image. The absence of time lag in the image is a great advantage for taking photos where the subject is constantly on the move. There is an auto focus system and furthermore, the resolution is extremely good. The only disadvantage is the absence of a `live preview` in most DSLR cameras.
Digital rangefinder camera – This is a portable camera suitable for theatre photography, portrait photography, street photography and candid shots. A rangefinder is a range finding focusing accessory attached to a digital camera allowing a sharp focus. Wide-angle lenses are more often used in rangefinders. Filters which absorb much light or change the color of the image can be used in this camera.
Main features:
Resolution – About 2 – 3 mega pixel resolution is enough for a decent digital camera. Resolution is a measure of the number of pixels on the sensor that create the picture. It is an important factor for printing a larger image or cropping it. Usually, the higher the resolution, greater the cost.
Type of lens – A glass lens gives a better quality picture than a plastic one. Again, a zoom lens adds greater versatility.
Close-up mode – Many digital cameras have a special close-up mode which allows one to take close-ups of extremely small objects like jewelry and coins.
Manual mode – Modes of different types are there, which enhance the quality of photographs in a particular situation. Portrait, landscape and close-up are the special exposure modes. Shutter speed and lens opening can be maneuvered in the manual exposure mode. Burst mode allows a number of pictures to be taken in rapid succession. Different filters can be used to provide beautiful effects. Extra flash modes can also enhance the clarity of the picture.
ISO – This value normally varies between 100 and 400. A higher value indicates that more number of pictures can be taken in dim light.
Conclusion:
After going through the different types of digital cameras and their features, one should ask oneself about the objective of buying a digital camera. The type of photography, the experience level, weather conditions, the budget and portability are all factors which need to be taken into account before purchasing a digital camera.
A higher mega pixel rating means a higher price. If large prints are not the criteria, then mega pixel rating around 4 should suffice. Lastly, reading reviews of the different digital cameras available for sale might just be the best option before purchasing an actual one.
