Digital Camera

A digital camera battery is probably the most important digital camera accessory. Some digital cameras can consume power at an alarming rate, providing no more than a few hours of continuous shooting time before the battery is drained. Other cameras are renowned for the long life of their digital camera battery which allows users to snap away with barely a thought to power consumption. It is important to know how you intend to use your camera and what type of battery it needs.

There are two types of digital camera battery. The most widely available digital camera battery is a standard AA-size battery. The other type of digital camera battery is a rechargeable battery that is made by the manufacturer, otherwise known as a proprietary battery.

A proprietary digital camera battery offers the advantage of being lighter and more compact, but they are substantially more expensive, making the prospect of buying one or two backup sets much less appealing.

The alkaline AA-size digital camera battery usually has a very short life - less than an hour in extreme cases - when used in a digital camera. This type of battery makes an acceptable emergency backup, especially if you are travelling with your camera. However, the Nickel Metal Hydride (NiMH) digital camera battery can be used instead of the alkaline ones with a charger and this rechargeable NiMH digital camera battery has a substantially longer life at an affordable price.

Another type of AA-size battery is the non-rechargeable Lithium batteries and rechargeable Nickel Cadmium (NiCD) batteries. The lithium digital camera battery has a superior life to alkaline AA’s and offers good cold-weather performance but their price and non-rechargeable nature make them less useful than rechargeable NiMH batteries. It is also important to ensure that your camera can take a lithium digital camera battery. On the other hand the NiCD digital camera battery offers the advantage of retaining their charge while unused, unlike NiMH cells, but have shorter lives and need to be discharged completely before recharging which can be extremely inconvenient.

The LCD screen of a digital camera is responsible for consuming the most power from a digital camera battery so it is worth only using the LCD when necessary to help conserve the battery life. Always try to carry at least one backup set of batteries, especially if you plan on being away from power outlets for an extended period of time. The universally-available alkaline AA-size battery can make a convenient emergency backup if your regular digital camera battery fails.

Taking photographs of the people in your life is simple with a digital camera. We all have collections of images which represent the important people and events in our lives. Some of the pictures are great, but some leave our subjects stiffly posed, lost in the sea of a cluttered background, and often lacking personality as they stare back with the same “posed” face as in every other photograph. So how do we capture the detail and the personality so that the image saves for us a more meaningful record of a moment or a person?

Obviously, professional photographers take control of the background and lighting, direct the pose of their subjects, and use a great deal of creativity with props and camera controls to assure the highest quality image. For the average person however, candid shots are more effective in capturing the true meaning or personality at a given moment. For these individuals, following just a few basic tips can go a long way in obtaining photographs that will become a treasure for many years to come.

The subject should be the focus of the picture. Avoid a cluttered background so that it does not distract from the subject. Using the viewfinder allows the photographer to determine how the shot will look. If the background is too cluttered the subject can be moved, but in more candid shots of individuals, holding the digital camera in a vertical position sometimes helps to eliminate some of the background.

Step in close to capture more detail. For an image that captures the true personality and emotions of the subject, a photographer must get facial detail. When taking a candid shot and stepping in closer would disrupt the moment, use of the digital camera’s optical zoom or telephoto can have the same effect.

Some shots don’t require posing. Many of the most meaningful shots are taken as subjects interact or are engaged in an activity. From images of children at play, a spouse reading the morning paper, a parent and child talking, or grandma gardening these are the moments that reflect the true personality of subjects.

Happy is good, but there are other emotions worth capturing. It adds depth to a subject when images reflect other feelings such as humor, concentration, relaxation, or even boredom.

A relaxed subject makes for a better photograph. When posing subjects, many photographers suggest talking to them to get them to relax and reveal more of what they are feeling or thinking. A natural, relaxed posture will provide a better image than that of a person standing rigidly with their arms crossed. A subject may be seated with their head resting on their hands or standing with their head at an angle and hands in their pockets; posture varies in real life and should be varied in photographs as well as it reflects the subjects mood.

It is sometimes acceptable for a subject to be looking away from the camera. Just as with expressions on the face and posture, variations in where a subject is looking can work well in capturing a more meaningful image. Whether it is a child daydreaming as they gaze out of a window or simply an attempt to catch the profile of an adult as they drink their morning coffee these images which most accurately capture a subjects personality don’t always require that they face the camera directly.

Use the portrait setting on the digital camera for individual shots. The portrait setting will set the depth of field to focus on the subject.

Focus on the subject can also be enhanced by framing them. For instance, a subject may pose in a window, an arbor, a doorway, sitting on a swing, or something similar to focus attention in the image on them.

Lighting does matter. Although natural light outdoors is generally the best lighting for photographs, direct sunlight must be used carefully as it causes harsh shadows. Using the fill flash on a digital camera can help to reduce such shadows. Otherwise, taking shots in the shade, on an overcast day, or in the morning or evening when the sun is less harsh can help alleviate this problem.

For images that truly capture the personality of people that matter to us, photographs taken by family members can offer a dimension that is very difficult to capture in a studio. A willingness to experiment with more relaxed and natural poses or to avoid posing completely will provide a collection of photographs that reflect and record our lives more accurately.

Disposable Cameras (also called single-use cameras) first came on the market as film cameras. You would take the entire camera back where you bought it and they would crack it open, take out the film and process it, resulting in photos that were virtually indistinguishable from photos taken with a more conventional camera. Now, following the trends in conventional cameras, there is a choice between using film or digital disposable cameras.

Some people think digital cameras are too hard to use; the disposable digital cameras offer a solution. Disposable digital cameras still have all of the great features that attract people to digital cameras such viewing your pictures before printing and photo manipulation. With a disposable digital camera, you get a flash, a timer, and a viewing monitor (depending on the model you buy). This means that you can see whether you want to take the picture over or not, as you also have the ability to delete an unwanted photo, and retake it if you have the opportunity. Additionally, a free picture CD is usually included with your prints in a disposable digital camera package.

Does a disposable digital camera offer the same features as a regular digital camera? It does offer the most frequently used features, but you will not get zoom or night shots, or most of the other bells and whistles that come with a $400.00 camera. But disposable digital cameras do not cost anywhere near $400, and they do allow you to leave your valuable cameras safe at home and still have the technology that you may crave in a camera for between $10.00 and $20.00, and sometimes even cheaper.

However, you cannot connect your disposable digital camera to your PC or Mac. The photos must be developed at a retailer that provides the proper equipment for your particular brand of disposable digital camera. This may actually be a plus for the technologically challenged, though, since you don’t have to hook up the wire, crop, fix the color — no need to waste hours in front of a computer, as it’s all done for you. Your time is valuable.

But perhaps no product has been more affected by digital technology than the camera.

Although it may seem like digital cameras are a recent phenomenon, the first digital camera available on the U.S. market was released by Kodak some 15 years ago. The DCS-100 had 1.3 megapixels, which are units of graphical resolution digital cameras use to display data, at a less-than-reasonable price of $13,000.

Fifteen years of advancement in digital camera technology has not only increased the number of megapixels for entry-level digital camerasit’s hard to find a digital camera with fewer than three megapixelsbut brought the cost of digital cameras down to far more reasonable prices (under $80 at some stores).

And thanks to the storage capability of digital camerasperhaps the biggest advantage to digital camera technologyusers can view photos on an array of outlets like the camera itself, a computer monitor, on web pages or on paper after developing them on printers. Some digital cameras, or autonomous devices, have rendered computers obsolete. Through the camera’s USB port, the camera can connect directly to printers to develop pictures. Even televisions, DVD players, entertainment gaming systems and cell phones are capable of reading and displaying digital images.

But because digital imaging is ubiquitous in its availability, it’s important now more than ever to understand the particulars of digital cameras, the best (and worst) ones to buy and how to take professional-looking pictures.

With the electronic guide, you’ll learn how to do that and much more, including how to avoid being ripped off when buying a digital camera, how much is too much for a digital camera, the three levels of digital photography, and how poor skill can’t be negated by cameras with all the bells and whistles.

A great photograph depends on a lot of things. A great view, a good camera, good light and of course, aperture
settings and shutter speeds. What exactly does the aperture do? It is, basically, an aperture or an opening. The
size determines how much light enters the camera through this opening and falls on the image sensor to form the
digital photograph. Did too much light get through? Your photograph could be a washout. Was it too little? You’ll
get a dark picture.

Apertures come in different sizes - all classified as ‘f’ numbers. Each number lets in double the amount of light as
the previous one. The standard is between f/1.8 and f/16. The smaller the aperture, the less light that will be let in.
So an f/16 lens will let in half the amount of light as an f/8 lens. The aperture works in conjunction with the shutter as well when it comes to the amount of light let in. The speed at which the shutter opens and shuts is also a factor that determines the amount of light. When it comes to fast-paced action, a fast shutter speed is essential to capture the motion. For a landscape or a posed photograph a slower shutter speed is fine.

A photographer who is extremely particular will adjust both the aperture as well as the shutter speed. A perfect balance between the two could very often bring about that one perfect picture. It needs a trained eye in order to judge perfectly exactly what the settings should be. What he would also take into account is the depth of field, that is, how much of the image remains in focus. In larger apertures, there is just a short range that is in focus, whereas smaller apertures have a much deeper range, going from the foreground close by to way back, deep into the background. It would all depend on the kind of shot to determine what the settings should be.

For those of us who do not have the inclination, the understanding or the patience, we can always resort to the automatic setting. It’s simple, the camera does all the work of adjusting for you and you get a good photograph. It might not be a work of art as might a photograph that a true professional photographer might have taken, but most cameras today give you a very acceptable quality.

Why do we need aperture settings at all? The simple, old cameras didn’t have any. If you choose a camera with aperture settings like a telephoto, wide-angle and maximum aperture features, you know that even in an automatic setting, you will get different kinds of pictures, not the same, flat look. It gives you the freedom to take any kind of shot, anywhere, in any light. Otherwise you might find yourself restricted to typical, posed cheesy pictures without too much character or depth.
