When it comes to photography, the digital wave is very much in evidence and yet, both operate on the same principles. Both have a lens, an aperture and a shutter. The difference lies in how the image is formed. Classic or traditional photography uses film on which the image is captured and then developed in a darkroom with chemicals to give you negatives. These need to be printed before you can see the picture in its final form. In a digital camera, you bypass all these processes because the image is captured by an electronic sensor. You aim, click and almost immediately, you can see the picture you took in the viewfinder. There is no developing, no negatives, no printing. Just the sensor which is actually millions of pixels or megapixels where light gets converted into a number.

The pixels in a particular camera are constant. So if you were to print out a picture that is larger than the usual size you print, you would find that it is not as sharp as the smaller size. So you should keep this in mind when you are buying your camera. If you feel that you will probably want to print larger pictures, go in for one with a greater number of pixels. If you are not terribly particular, it does not really matter. Apart from a slight difference in sharpness, the picture quality does not suffer. You could find out from your photography store just how big a print it would be all right to print from your camera.

The greater the number of pixels or picture elements the sensor has, the better the picture quality and of course, the higher the price. In fact most cameras have a greater number of pixels, also referred to as ‘resolution’ than a regular computer screen. The resolution is expressed in megapixels. The number of pixels for black and white photographs can be a smaller number as it only involves the two colors and the many shades of gray in between. The number of pixels needed for color photography, however, is much more. The greater the number of pixels, the better the color quality. Digital cameras usually come with the capacity to produce 16 million colors expressed as 24 bits a pixel. Professional cameras have been known to go up to 48 bits a pixel which translates to nearly 300 billion shades!

Of course if you are shooting the local forestry this would not really apply. A tree is not likely to get offended if you shoot it at a moment when its branches look forlorn and sad – but a person might.

For example, you’re prowling the backstreets of some Third World city, or even your own, trying to capture a particular mood. You see an old woman in your line of sight looking tired and world weary. Nonetheless, you see her noble expression and a certain grace in her pose, so you take the shot.

Later you can fix the shots in photo editing software, give it a good color balance and your friends will admire it. You get that pleasure for your efforts – but what did your model get?

Back in the day when I first began taking photos, I came upon a man coming towards me along a city street on a crutch. It was a powerful image, so thinking myself a god with a Canon I boldly took the shot. The subject got very upset – and I immediately saw his point: who wants to be immortalized looking your worst?

When I returned to the darkroom I threw the negative out and made a vow not to do that again. Should I have asked for his OK first? Because he most likely would have refused permission, this would not have resolved the situation. The point was, why was I taking that shot in the first place? If I’d thought about it I would have taken a shot from the back and at least spared his feelings.

Sometimes the true value of the image when you take a candid shot, is in the subject not being aware of you. These images can be wonderful but the effect could be ruined by you stating your intention beforehand. However, what you can do is once you’ve got your shot, approach the subject, let them know you’d like to take a photo and do the best job you can of taking a flattering picture of the person. It’s likely they will never see it but what holds true is that it is the thought that counts.

Another suggestion, often appreciated in poorer countries or areas where the local people have been assaulted photographically on a daily basis by throngs of tourists, is to offer at least some polite financial exchange for the modelling services provided. This is usually appreciated and it’s good for your conscience.

Some other examples: one time I did my own personal photo essay on a school. It was impossible for me to provide all the teachers and students with a print each so I burned a CD of some of the better shots and gave it to the head teacher.

Another time, I shot a dog class and made some small prints of the ten best shots and gave them to the trainer to pass out at the next class.

All of this is simply good manners, and showing good manners is always well received. Also you will probably find yourself to be welcomed back in the case of having to re-shoot anything later.

Try it.

We are living in a digital world. Digital technology has become the spine and the nerve of the modern world. For an instant, if you meet someone on the road, just see what he or she is carry and you will find one or more of a mobile phone, an MP3 player, a laptop, and a digital camera. All of these are used not just by the rich anymore, as they have become accessible to all.

Among many digital devices that are available for day-to-day on-the-go use, hd digital video cameras are quite important. Once the hd digital video cameras were manufactured by one electronic device manufacture company, the other major brands such as Sony, LG, Canon, and JVC started selling their versions in the market, and because of the easy availability prices of these hd digital video cameras are quite reasonable as well. Usually the price of a digital video camera may range from 0 to 0, and it depends on the quality of the video produced and the features offered by the camera. The most basic ones would have all the functions you need like zooming capabilities, but it may not have much storage capacity or may be too heavy. The best digital camera will be very light, have great resolution and also be very user friendly. hd digital video cameras offer many things over the traditional analog video cameras in each and every way. The storing of video image and transferring it to a computer for editing is just a few clicks away. If an old-style video camera had been used the whole process would be much longer and a lot more tedious, with the need to use cassettes and also the chance of the quality of video going down with each copy taken. hd digital video cameras make documenting that special day a lot easier as they can be stored in a personal computer, edited, emailed, and manipulated on the computer itself, which meant that the quality would not be affected. The expensive video cameras have a lot of space for storing the videos, and they have the memory installed internally, so there is no need of changing the memory cards like we used to change the cassettes in traditional video cameras

Currently, hd digital video cameras are available in many forms. Although the digital cameras manufactured recently are designed for photography, there are cameras that are capable of recording videos as well., as today most of the new models of digital cameras that have come out have the option of recording a video as well. There are phones that come with the option in-built as well, and so hd digital video cameras need not come in the same package for the job to be done.
