The future of photography is in your hands, and itâs becoming all digital!
Now you can compose and view the exact picture youâre going to take, using your cameraâs full liquid crystal display
(LCD) screen. Review the picture an instant after pressing the shutter. If your computer is nearby, you can upload it seconds later, view a super-large version on your display, crop, enhance, and then make your own sparkling full-color print â all within minutes!
When you go digital, you never need to buy film or wait while your photos are processed in a lab. You decide which images to print and how large to make them. You can display your digital photographic work framed on your wall or displayed proudly over your fireplace. You can make wallet-size photos, send copies to friends in e-mail, or create an online gallery that can be viewed by relatives and colleagues over the Web.
Digital photography gives you the power to take pictures on a whim, or to create careful professional quality work that others might be willing to pay for. The choices are all yours, and digital photography puts all the power in your hands. All you need is a little information on how to choose and use your tools, and how to put them to work. The most exciting thing is how rapidly the technology is changing to bring you new capabilities and features that you can use to improve your pictures.
Taking pictures with a digital camera:
Some differences in technique are required, as the digital image data is captured in a manner that is different from a film camera. Most digital cameras have a shutter that will make settings of focus and contrast when the shutter button is half-way down, and this process may add a delay to the time before the shutter operates.
When looking through a viewer, it is desirable to have a digital screen in the eyepiece viewer. One reason this is important is to ensure that certain types of scenes will retain the color elements correctly. U should be aware that many digital cameras can do poorly with scenes such as sunrises if they point the camera at the foreground slightly below the horizon and in line with the sun before pressing the shutter. This may result in an image that shows none of the color or brightness of the sky. However, if you use the shutter button to pre-focus (and pre-contrast) on the sky, and hold the shutter button half-way down as your re-direct the camera toward the preferred framing direction, you will see if the colorful features in the sky will be retained in the picture.
Generally speaking, a digital camera will use a shutter speed that is faster than a film camera, which relieves the user from having to steady the digital camera as much to avoid blurred pictures. Also, many digital cameras have an auto exposure feature that tends to make a setting of fast shutter and fast f-stop. Thus, an amateur photographer can do a respectable job with telephoto photography, where the narrow-angle view may be the only manual adjustment needed for point-and-shoot pictures.
Read the instruction manual for the camera to set up this feature. It may require that you press the shutter button halfway and hold it for a second or longer for this feature to become operational prior to operating the shutter.
Some of the better digital cameras do can an excellent job of taking close-ups, as their focus range may include four inches to infinity.
With the digital viewer on the back of the camera, you can have some assurance that a satisfactory photo has been obtained. However, it has limited resolution and limited ability to show a good display in sunlight. You can delete images from the flash card that you donât want and free up memory for additional frames to be shot on the same flash card.
For most purposes, u will be satisfied with images in the JPG format. With a 2 Mpixel camera, each frame will require about 0.5 MB of file space. Thus a 32 MB flash card will serve to retain up to 64 image frames.
Why still use your old âfilmâ camera when you can go Digital?

Video surveillance cameras in the form of closed circuit television were first used in 1942 in Germany. It was first installed by German engineer of Siemens AG at Test Stand VII to monitor any cause of malfunction or problems from V-2 rocket launches. Some surveillance cameras are installed directly on the rockets to monitor the different stages of the launch and it uses radio transmission to transmit back to base the video images.
Today the technology of video surveillance cameras is used for different purposes. It can be for crime prevention, industrial observation or traffic watch. They can be installed anywhere and everywhere like banks, casinos, offices, airports, government buildings and other locations which need vital protection. Video surveillance cameras are invaluable tools to post crisis and post crime investigations as it was proven by the July 7 London Underground attacks wherein a close circuit television video surveillance camera was able to capture the picture of a suspect in the attack. Because of its usefulness, governments opt to use them more in public places in order to prevent more crimes. In the United Kingdom, they have one camera for every 14 people. The United States is starting to do the same however it is smudged in debates and controversies.
There are those who are for the use of video surveillance cameras in public places in order to prevent crime. On the other hand there are those who oppose it because they say it violates the rights of every citizen for privacy and it violates the Fourth Amendment which prohibits unreasonable searches and seizures. For those who support the use of video surveillance cameras they say that the need for public safety weighs more compared to the need for privacy. However, for those who would want to protect themselves it is now easy to purchase a video surveillance system for small offices or even homes.
Home surveillance cameras are actually hot commodities today due to the rise of security concerns especially in the United States after the cowardly terrorist attacks in September 11 of 2001. There are different home video surveillance cameras for the consumers interested in protecting their love ones and property.
There are wired surveillance cameras for permanent installation. These cameras cannot be relocated and are useful for important locations. These surveillance cameras however need professional help in order to be installed. Then there are wireless surveillance cameras which are the exact opposite of the wires cameras. Wireless video surveillance cameras do not need any professional to install and almost anyone can do it. These cameras can also be relocated anytime and anywhere so that it can cover every inch of the property. This can transmit either to television or computer systems. Then there are the spy or covert surveillance cameras. These are very popular since it can be hidden almost anywhere.

Especially in bad weather, we should avoid using in the rain, smoke, frozen weather or strong sunlight as far as possible. How to maintain your digital camera? Now I would like to share a number of digital cameras maintenance tips with you.
Prepare a package for your digital camera to protect it. This is very important, but it’s very easy to be overlooked by people. We usually put the camera into pocket conveniently or hold it by hand when we have finished taking pictures. But it’s not good for your camera. It’s necessary to prepare a compact package for your digital camera. It can be used for carrying cameras, SD card, digital camera batteries, and lens. And you’d better prepare a special package for liquid crystal display.
Clean the external of camera with a soft cotton flannel. First, open the panels of storage compartment and battery compartment, and clean the dust with a soft brush. Then clean the metal part of the camera with alcohol.

Dummy surveillance cameras can be excellent as security gadgets. Here are some suggestions and tips on what to look for and how to use them:
Buy a dummy surveillance camera based on your needs
Try to determine your real needs. A dummy surveillance camera can help deter a possible intrusion or trespass but it is severely limited by its design. If a burglar ignores it and decides to enter your property, you might have a lot of difficulty in producing video or photographic evidence. When considering the use of a dummy surveillance camera, keep this in mind.
Make sure you’re trying to resolve a low-tech problem
Understand the limitations of a dummy surveillance camera. A dummy surveillance camera will not work like a real surveillance camera. It will not be able to monitor suspicious activities. You cannot wire it to a remote recording unit in order to take photos or videos of areas you wish to monitor.
As such, make sure that the area where you want to use a dummy surveillance camera is well protected – locks installed, alarms in place and other physical barriers such as gates, fences, shutters or window grilles are present.
Consider other low-tech solutions as well. Installing lights, locks or a fence, for example, can increase the security of your property without requiring you to purchase additional equipment.
Make sure it looks like a camera
You could probably save more if you buy cheaper dummy cameras but make sure you don’t skimp on the quality. The more bogus the camera looks like, the least likely it will be able to deter any burglars or intruders.
Buy a dummy surveillance camera that looks exactly like the real thing. Choose one that has a red LED light for more a more authentic look. There are also dummy surveillance cameras that can pan from left to right at intervals of about 1 to 2 minutes. These are excellent choices if you’ll be using one in wide or long areas such as backyards or hallways. For large rooms or areas, a dome dummy camera will be a better choice.
There are also other features found in dummy surveillance camera models you might want to consider, such as motion detectors and alarms.
Keep the truth a secret
Be careful about letting other people know about your dummy surveillance camera. If you must tell someone, make sure you can trust them. To make sure that you leave no doubt in a potential intruder’s mind, install a sticker underneath the camera that says, “Warning: CCTV monitored”. That should send out a warning that your premises are being monitored, albeit by a fake security gadget.
You can’t just buy any type of dummy camera, learn how to buy top quality products that will help prevent your workers and nanny from doing what they should not.

If you are one of those who love taking pictures, then digital camera is probably one invention you simply cannot afford to miss! Smart and trustworthy, this one is probably the most imaginative development in the world of photography till date!
Digital cameras are electronic devices that capture as well as store images digitally, instead of on photographic films. A digital camera, however, needs a memory or a storage media to save these pictures. Some of the most popularly used storage devices include Floppy Disks, CD Singles, DVDs, Memory Cards (such as Microdrives or CompactFlash Cards, Memory Sticks, MiniSD Cards, MicroSD cards, etc), FP Memory and many others. Though storage devices such as Floppy Disks need computers, using autonomous devices, like the PictBridge Printer can ensure that you can print your pictures directly using a printer.
One of the greatest advantages of using a digital camera is that they, unlike the conventional cameras, can record, store, retrieve, remove, edit and manage your pictures as you may wish to. In fact digital cameras may also allow one to shoot and save videos of a considerable length. The sound and the picture quality ranges form one camera to another to a great extent, though in most cases a digital camera can surely allow you to shoot at least a reasonably good video.
Another great benefit of using a digital camera is that these devices are (in most of the cases) very portable, and can be easily carried around form place to place. Though one cannot say that these are not delicate, and need not be handled with care, one can sure stay assured of the fact that these days digital cameras are not very difficult to be taken care of either. If you can keep it safely in a cover, and handle it with reasonable care, and your camera is sure to serve you well. However, since in most cases digital cameras come with a long guarantee period, this is one thing you simply need not worry about!
Just like all other electronic devices, digital cameras also come with a wide rage of features that keep on adding and developing with the growth in technology. Though much depends on the price of the camera and the companies manufacturing it, there are certain features that have been found to be popular among almost all of them. These days it is not rare to find digital cameras allowing zoom, image adjusting, and automatic functioning (as based on the time set by you), when you go clicking pictures. Settings as to the picture color code, brightness, sharpness, etc can also be changed. Generally digital cameras also allow you to make your own picture or video albums, so that you can systematically save them all.
A digital camera works on battery, the life and the stand by time of which varies greatly, depending on the camera you are using and of course on the battery itself. Generally these are chargeable, so you know you can charge your battery anytime you need to. However, the best part of it is that, (depending on your video camera) the battery can work non-stop for a relatively fair amount of time. This means you can click away your pictures happily, without having to bother about the battery betraying you mid way!
These days almost all well known and even not so well known electronic device related company can be seen producing digital cameras. Needless to say, as more and more companies enter the market producing more and more sophisticated digital cameras, the more the prices can be seen falling with each passing day. Now in such circumstances, how can anyone resist having a digital camera of their own?!

A digital camera is a camera that takes digital photographs on a light-sensitive sensor. Many digital cameras can also record sound and videos besides still photographs. These cameras can store thousands of images on a small memory space. The users can also edit the stored images. They can also delete the stored images. Deletion of stored images will free the device’s memory which can then again be used for taking more photographs.
The digital cameras now-a-days are being incorporated into devices like mobile phones & personal digital assistants (PDAs) and vehicles. There are various types of digital cameras like video cameras, line-scan cameras, bridge cameras and live-preview cameras. The video cameras are further classified as camcorders, professional video cameras and web-cams. While a web-cam is attached to computers for video conference purposes, a camcorder is meant for the use of amateur photographers.
A Bridge camera often has a super-zoom camera lens that provides a very wide zoom range. These cameras are often confused with digital SLR cameras as their appearance is similar to each other. Many of the Bridge cameras store images inloss-less RAW format. They are generally lighter that DSLR cameras and provide images of good quality. Most of the compact digital cameras store images in Tagged Image File Format (TIFF) and Joint Photography Experts Group (JPEG) file formats. Some cameras also use formats like Design Rule for Camera Format (DCF), Digital Print Order Format (DPOF) and Exchangeable Image File Format (Exif).
Zoom camera lenses are designated as 3x, 4x, 5x etc. These designations refer to the ratio between the longest and shortest focal lengths. A larger zoom designation does not necessarily mean that the image cannot be magnified any more. A zoom lens is one wherein a photographer can vary the focal length of the camera lens within a predefined range. The zoom lens allows users to achieve a variety of perspectives and compositions. These zoom lenses come handy when the user has to capture images of a dynamic subject matter like an athletics event.
