How It Works?

Of the major technological gizmos ruling the roost, Digital Cameras deserve a special mention due to the wide usage they have been subjected to. Both at the domestic and commercial fronts, we could see an escalated use of Digital Cameras for capturing the images at an amazing speed. Whether you are shooting from a moving train or from a hill cliff, the images delivered by a Digital Camera will relatively be better than the ones shot on a normal Camera.

Digital cameras have revolutionized the concept of conventional cameras where in, with a single digital film you can go on taking hundreds of pictures before you reach the end of the film. True to its name, the images produced by a Digital Camera are of digital quality i.e. of better quality and visibility when compared to the pictures taken by an ordinary Camera. Then, why not go digital!

Parts:

People often wonder how a Digital Camera works and what all components are there inside its little belly. Some of the major components of a Digital Camera are battery compartment, flash capacitor, processor chip, USB connector, wrist connector, Top case, CCD, LED, secure digital card slot etc. Everything is automated with a Digital Camera; as there is a built-in computer which handles the functioning of the camera in an automated manner.

Functioning:

When you click on the button of the Digital Camera to take a picture, light will get reflected onto the digital sensor array and all the megapixels on the sensor get activated. The image will be transmitted through the color filters first and then it will be transformed into a signal that is analog in nature. This signal will then be passed through a special converter which gives it the desired digital form. Here a certain amount of patch work goes on like trimming your picture, shearing away the unwanted pixels and a final shape will be given to your picture which will be stored away safely in the memory card of your Digital Camera. At this stage, the image undergoes compression like JPEG format, to be able to be stored on the memory card. The image will be cleared off the unnecessary pixels during the compression and the changes that are made this way are irreversible. The data once lost cannot be retrieved after the compression process.

Megapixels:

We often hear people talking about megapixels whenever they are about to buy a Digital Camera. These megapixels are nothing but photosites that help you in quantifying the intensity of light. Pixels have no role to play in the colors exhibited in your photo. Several millions of megapixels come together to form the plane of the digital sensor and it is based on these megapixels, we can have a fair idea of the quality of the picture that is likely to be delivered by your digital camera. The more megapixels your camera has the more it will be beneficial for you; you will get a clearer and finer image. If you need a bigger print of your photo on paper then you better opt for a camera with more number of megapixels. Enjoy good quality images with the best Digital Cameras in the market. Happy Shooting!

Digital cameras are expensive and demands good amount of your energy and time before you decide upon a piece for you. Buying a digital camera involves a lot of consideration and market research to know about various models, their functioning and price ranges. Before you hit the market for a whirlwind trip of cameras, we suggest that you do some self-assessment like why exactly do you need a Digital Camera, your budget etc.

Some of the things you need to look for before buying a Digital Camera are:

Aim: What for do you need a Digital Camera? To take pictures of your company operations, your family gatherings or your annual family vacations! The answer to the above question will decide what kind of camera you will need and how much money you need to shell out for that.

Basic: If you want a basic camera with a minimum budget do not go for the ones with huge lenses and accessories. Unless, you have some grounding in photography you will not be able to operate them.

Second Deals: If you don’t want to compromise on the type of camera you are buying even when you don’t have budget, you can try second hand deals available online. Some online sites specialize in selling and buying second hand goods, so you can try your luck there. This measure will be handy when you are totally new to a Digital Camera and don’t know how to operate it at all. After you get used to the Digital Camera, you can think of buying a brand new one.

Image Quality: Just because a camera has long lens, great to look at, doesn’t necessarily mean that it will deliver great pictures. Choose a camera that is endowed with large sensors, high Megapixels count (min. 3) and good color features. Apart from megapixels, several other features like contrast, brightness, color etc come into play in defining the quality of the picture.

Speed: Some Digital Cameras take unduly long time to prepare themselves to shoot and to get ready for the next shot. You better check out this speed first before making your final decision. For travel trips cameras with less shutter-time will be ideal.

Compact: If you are buying a camera for personal use, make sure that the camera you are buying can be operated by any body. It should be easy to hold and has all the special features that a normal camera user requires. Compact Digital Cameras are easy to use and carry; they can be taken anywhere you want to without having to worry about your cabin luggage.

Clear: Go for a camera that demands low-maintenance and do not confuse you with a clutter of buttons and incoherent features. Acquaint yourself with each and every button and the feature the camera has. Do not forget to take a hard copy of the user’s manual of the gadget you are purchasing. Carry it along so that it can aid you in troubleshooting later.

Resources: If you have a darn good camera but a poor printer and not-so-nice computer, the image quality of the pictures will surely disappoint you. Generally, the manufacturer provides an image editing software along with the gadget. All the additional picture tools should be collected by you alone.

Memory Cards: A Digital Camera should not only carry a good in-built memory card, but should also have a facility to accommodate additional memory card which you might have to use when in need. The best practice is that, once you are done with transferring your pictures to your computer, format the memory card before storing it away. That way, you need not worry about memory when you are bringing on your next photo shoot.

Batteries: Batteries get used up fast in a shooting-spree. Have an extra pair of batteries at hand or else use rechargeable ones. Thus, you can avoid spending more money on batteries.

Hope all the above pointers have broadened your knowledge about Digital Cameras and the factors to consider while buying them. Do not bank on the megapixels alone when you visit the electronics store next time. Get the camera of your dreams today!
