Digital cameras are revolutionizing the world of home and professional photography, but they are married to memory cards just as traditional cameras are married to film. Making the best use of memory cards can have a very big impact on your enjoyment of digital photography. Choosing the right memory card for the job can be as important as choosing the right film for a traditional camera.

If you are new to digital cameras, the digital camera memory cards are the most important parts of any digital camera, without which they may not work at all. So if you are handling a digital camera or planning a purchase, you must know more about the memory cards used in these cameras.

Something many new digital camera owners find counter-intuitive is that bigger is not always better with a digital memory card. The actual response speed of your digital camera can depend greatly on the memory card it is using. The speed that your camera writes new pictures to the digital memory card is partially dependant on the transfer speed of the digital camera but is also dependant on factors in the memory card itself. Memory cards that have “buffers” can take the data into a faster type of memory and then transfer the data from there to the slower “flash memory” which provides the main storage of almost all digital camera memory cards. Some digital camera provide their own buffer memory to allow you to take your next picture while the previous picture is being transferred to the memory card.

When you delete an image from the memory card of your digital camera, the flash memory is “reconfigured” because of special issues having to do with how this memory stores data. Normally this is an issue that you don’t have to worry about at all. However, if you have a very large memory card and delete an image, you may experience a several minute delay while “house cleaning” is performed on the memory card. Because of this, do not delete images while you are taking pictures. Instead wait until you are at home, your hotel or in the car before reviewing your pictures and deleting the ones you don’t want. Smaller cards take less time for this “house cleaning” so many experienced digital camera owners will choose to have more than one medium sized memory card instead of one very large one.

Now the question arises-how many memory cards are enough for your camera? On an average basis, you must have at least two memory cards for your digital camera. That is, if you are using it in a normal and average fashion.

Most professional photographers choose to carry about four to six memory cards. This helps them shoot smoothly and constantly. If they run out of memory, they just take the loaded card out and insert the fresh one. Because memory cards can malfunction (just like traditional film canisters, but not as often), you should choose to have at least two memory cards at all times. By having at least two cards, you can work with one and keep the other in reserve for emergency. Having at least one extra memory card for your digital camera will also ensure that you have the backup protection needed if you run out of space on your first card or in the possible event of the first card malfunctioning.

The next important issue is how to take proper care of these memory cards. The memory cards may seem like some small and fragile piece of technology, but they are actually fairly sturdy. The flash memory is encased in a stiff plastic shell which can withstand normal wear and handling. At one end of the memory card is either a set of little holes or copper strips. These are the sensitive part of the card. Any voltage source or a large jolt of static could corrupt the memory and probably cause permanent damage to the card. When the card is not in your camera, it is best to keep it stored in a protective case or in your camera case. Putting it in your pocket could cause a short (from your keys perhaps) or dirty the electrical contracts. There have been instances where the users have misbehaved greatly with them and the memory cards have yet survived and continued to function correctly. But, this does not mean that one should not care for them.

When it is time to transfer your data from the memory card to your PC, it is best to have a memory card reader, or have a PC with a built-in reader. The data cables provided with most digital cameras are very slow compared to the speed of a “direct reader” and it is often easier to review, copy and delete images from a memory card when using a reader instead of through the data cable connection.

When traveling, X-Rays have never been shown to corrupt the data on, or damage, a digital camera memory card. The memory card is also not magnetic in nature so the motors in the X-Ray machine’s conveyor belt should not be able to cause any harm either.

Armed with knowledge comes the power to benefit from that knowledge. If you have learned something new about digital memory cards, hopefully you will benefit by enjoying your digital camera more and finding more opportunities to take great pictures.

If you are embarking on a hobby or even a professional career in photography, you have a multitude of models and features to choose from. Instead of getting lost in the sea of choices or getting stuck with the wrong model, you can base your decision on certain features that cater to the specific requirements that you have. Your choice of a camera can be narrowed down based on a few key evaluation criteria. The parameters discussed here will serve as a simple guideline to help you put into perspective the features that you might like to have in your camera system.

These parameters are discussed at 2 levels:

-Based on degree of functional use of available features
-Based on the type of photography you want to attempt

–>Based on degree of functional use of available features

A person who is happy with his or her camera model usually responds with the following words of praise.
‘Incredible ease of use’
‘User-friendly controls’
‘Intelligently and thoughtfully designed’
‘Excellent value for money’
‘Light and compact’

These are the kind of terms that you will come across from camera owners who are satisfied with their camera models. These superlatives sum up what people usually look for or could look for at an overall level in their camera. It is a broad evaluation based on design elements, size and affordability,

Before you make a decision to purchase you should explore a little further and study the type of features available to you. Unless you make the attempt to understand the features at your disposal, there is the risk of being stuck with a model that does not suit your particular requirements. Let’s take a look at what features you should look for, as well as the features that you should be wary of when you choose a camera system.

–>Features to Look For

1. The lens is by far the most important device in your camera. The quality of the lens ensures the sharpness of your image. The camera lens is described by length (given in mm), known as the focal length of the lens. 50mm is the standard focal length in a lens. A lens of shorter length is known as a wide-angle lens and is used usually by landscape photographers. A lens with focal length greater than 50mm is called a telephoto lens and is especially useful to professional photographers in capturing distant images.

There are also cameras with a zoom lens. A zoom lens can offer various focal lengths, so you have a lens capable of many focal lengths. Simple put, when you use a zoom lens you can make your subject bigger or smaller within the frame.

For instance, a wide-angle zoom can cover a range of focal lengths below 50mm, or a telephoto zoom gives you a range of higher order focal lengths. Some superior zoom lenses can take you from wide angle to standard and through to telephoto ranges. The power of the zoom lens is defined by the extent of magnification from a lower focal length to a higher end and is given as 2x, 3x and so on.

Some lens tips:

–A 50mm or 100mm lens is considered adequate for most non-professional hobby users. The professionals usually go for telephoto lenses of 200mm or more. A lens with higher focal length costs a lot more. Most beginners don’t need to invest in a telephoto lens.

–Check if your camera is compatible with the range of lenses that the manufacturer of your model has on offer. Most manufacturers have hundreds of lens options on offer and your requirement for lenses varies as you progress in photography. Your camera has to be compatible with lenses of higher focal length and speed. If you are planning to upgrade your camera by buying another model from the same manufacturer, check for compatibility with older accessories so that you can put to use some of the lenses already available with you and save yourself an additional expense.

2. Depth-of-field preview button

A depth-of-field preview button is a necessity if you want to achieve better focus. It allows you to identify the area that will be in focus in your photograph. This area is referred to as the ‘depth of field’. When you adjust the focus in your camera the preview button is a useful tool that can help you vary the focus and depth of field in different shots.

3. Image sensor resolution

In digital cameras, there is no film in use but this is instead replaced by a device called the image sensor. The image sensor renders colors, is sensitive to light and is the device that captures images in small pixels on its surface.
Image resolution is a measure of the sharpness or level of detail in photographic images. Image resolution is expressed as a number and is measured in mega pixels. High-end professional use cameras have an image sensor resolution of around 12 mega pixels and the most advanced professional models go up to almost 14 mega pixels. At the mid range you have camera models with resolution ranging from 2 – 6 mega pixels. To deliver large format prints of superior quality, you should go for models with resolution greater than 3 mega pixels. At the lower end, you have models of 1 mega pixel or less and the sharpness of the photograph is slightly inferior compared to cameras with higher values of image sensor resolution. Lower pixel models are best suited for small format prints.

4. If you have the facility for Auto-bracketing it can be a very useful tool. Auto-bracketing enables the camera to automatically take 3 exposures or in some cameras 5 exposures of the same shot by varying the Exposure Value (EV) to lighten or darken an image. Each of the images will be slightly differently exposed and this is a great tool to ensure that you capture the moment perfectly. You can bank on at least one being a properly exposed picture. This tool comes in handy especially for professional photographers.

5. If tonal quality of the photograph is your top priority when you choose a camera then it is best that you go for a digital camera. Photographic prints of scenes captured on a digital camera have a level of tonal quality that is far superior to best quality traditional prints.

6. There are sophisticated camera models available today that can capture movement and audio-visual images. If you want to go beyond static images and capture the first steps of a child or activities during family get-togethers, then you should look for a camera with these advanced capabilities. It will create a better experience when you go down memory lane. The Kodak Easyshare LS753 Zoom Digital Camera is one such model that offers audio-visual capability.

–>Features to be Wary Of

Some features or the lack of certain functions can prove to be a stumbling block for a photographer. Be careful when you select your camera system and pick those models where such drawbacks are minimized or not present. Being aware of such drawbacks is important if you want to make a smart choice.

1. If you want to go in for a camera model with a zoom lens, look for an optical zoom, not a digital zoom. The optical zoom provides variable focal length whereas a digital zoom merely increases the magnification in the center portion of the picture. If the camera you choose has both optical and digital zoom, then make sure that you can disable digital zoom

2. Some cameras are not all that effective in low light conditions and dark places, the flash a not powerful enough. Be sure you don’t select such a model

3. The shift between exposure-modes should be a simple one-step process. In some models shifting between ‘shutter priority’ and ‘aperture priority’ takes longer since it is a little more complicated, involving more than one step in the process of shifting between modes.

4. In some camera models you run into the problem of dust collecting in the film compartment. Look out for any obvious fine openings that can cause this problem.

5. Slow and noisy Auto Focusing can be irritating. Look for a quieter model.

6. A camera has to have the four key exposure modes: auto, manual, aperture priority and shutter priority. There are models with many more exposure modes but choose such models only if your requirements warrant the confusion that goes along with having a whole host of exposure modes.

–>Based on the Type of Photography Your Want to Attempt

You choice of camera and the functions that you need depend quite a bit on the type of photography that you go in for.

1. If you are into wildlife photography, look for a camera that includes Center-weighted metering.

Center-weighted metering is considered best by wildlife photographers for the flexibility it offers. With the center-weighted meter the attention is on the center of the frame as the meter reads the light reflected from the subject. The sensitivity of the meter is concentrated on the subject located at the center of the picture frame. You can adjust the size of the sensing area to 8mm, 15mm or 20mm based on the size of the subject and its distance from you. Nikon is credited with introduced the world’s first Center-Weighted Meter.

2. For landscape photographers, the key features suggested are -a spot meter, a wide angle lens and a memory exposure lock. These three features are considered the perfect tools for landscapes.

The spot meter allows for creative thinking when you compose your shot because the spot meter has a major role to play when you want to meter only a small portion of the scene. The spot meter allows for concentrating the meter’s sensitivity on a chosen spot of the scene during exposure. Using a spot meter can be time consuming but its application in executing creative ideas makes the time spent worthwhile. For instance, taking a shot of the sun setting over the sea or capturing the pattern of snow atop a mountain peak can be done with the help of a spot meter. The memory exposure lock is the mechanism with which you can lock the spot meter reading. The camera will use the locked in reading when you click for an exposure.

A wide-angle lens is capable of highlighting objects in the center or foreground. In landscape photography the tendency is to usually have a prominent object like a tree, landmark or person in the foreground to emphasize the scale of the picture against the distant elements in the scenic setting. This feature brings out the depth in the photograph and the wide-angle lens makes this effect possible.
3.Those who indulge in trekking and mountaineering and are looking for functions that is adaptable in contrasting light conditions such as night-time camp fire or early morning at sunrise or at sun-set, should go in for a feature known as ‘multi segment metering’. The multi-segment meter divides the frame into several areas and takes into account the different tones of color in the scene.

4. If you are an inveterate traveler then the camera size and weight should probably be a key consideration. Compact, light cameras are ideal during travel or for trekking.

5. Digital cameras are evolving at a rapid pace in their capabilities. Available to you are cameras that can offer ‘programmed scene modes’ for different types of photography situations and these options are available to you within the same camera model. For instance, the Kodak Easyshare LS753 zoom digital camera has around nineteen automatic scene modes. The mode can be varied depending on the subject and the scene before you, such as – children, snow, beach, backlight, flower or fireworks. This model also has the night mode for night shots and the sport mode that allows you to capture action without the problem of blurring. If your interest in photography is varied but you don’t have the technical knowledge to change the settings for different scenes and subjects, then a digital model with automatic programmed scene modes is your best bet.

6. For beginners still learning the ropes of photography, the criteria for selection should be on features that simplify usage rather than those that complicate the process of learning. For instance, some cameras have a feature called the viewfinder LED. This feature allows the camera to determine the shutter speed that is required for a proper exposure. If you don’t use the right setting, the LED changes from green to yellow to give a warning that the shutter speed is too slow to get a sharp picture. This is a form of auto-assistance that can be a big help to a new photography enthusiast.

To sum up, it is imperative that you explore all your options before you make a final purchase, no matter how time-consuming this process may be. The Internet is a great way to do some pre-purchase information search. Do your Internet research to shortlist options – most major camera manufacturers have websites with extensive product descriptions and price details. You can also do your cost comparisons online at sites like shopping.com. Shopping.com lists 410 products in Point and Shoot Cameras, 153 products in 35mm SLR Cameras, 1,500 products in Digital Cameras besides other camera types and accessories.
Once you have a shortlist, make a visit to the retail outlets. Check out a few alternatives brands and models based on your requirements. Assess them on size, weight, ease-of-use of controls and features. A beginner usually looks for a user-friendly model with significant simplicity in operation. Camera models with manual dials are considered easier to use and quicker to learn and manage by some beginners. But some prefer the panel of buttons. Choose the type that suits you. Ease of use in placement of buttons has to be checked. You have to be comfortable with the ‘layout’ of the various buttons when you handle your camera. The placement of the control layout has to be logical.

And then finally, zero in on the camera that you want. Anyone who wants to experiment, learn and enjoy photography should look for a model that is versatile. For example, your ideal camera could be one with a combination of optical zoom lens of 3x magnification (this is a standard level), a depth of field preview button and an image sensor resolution of at least 3 mega-pixels.
If you make the right choice, your camera system can take you on a long fruitful journey of creativity, learning and fun.

Professional Photography Tips
A lot of flashes for regular cameras are small electronics that are
built-in. Professional photographers use more expensive and advanced
equipment. Professional flashes all have manual controls and are
outside of the unit, providing much more light with much better
controls. Flashes are mostly used indoors as the main source of light
when the area is too dark to get quality photographs. In weddings, for
example, flashes are also used in sunny conditions, in order to fill
the shadows. Harsh sun lighting can ruin a good photographs and wedding photographers use their manually set flashes to fill some of
those dark spots.

Red eye ?obe gone?
“Red eye” is one of the most commonly mentioned complaints in regards
to built-in camera flashes of point-and-shoot cameras. Having all the
people in your images with vampire-like red glowing eyes is not
really pretty for any subject, however this is one of the most
difficult challenges the flash has to offer. The problem comes from
the fact that the human?Ts eye retina mirrors the red light from the
flash right back at the camera. So the problem is essentially not
really camera?Ts fault. Some cameras have a “red eye reduction”
software or even features that emits a few pre flash light flashes
that aim to get the iris of the eye to contract by the time the main
flash comes the chance of the red eye effect appearing is reduced.
Red eye reduction software work with red color of the eyes, in order
to darken the color. Professional flash units usually don?Tt have
such big problems with red eyes.

Shadows
Using the built-in camera flash can result people in photos looking
extremely bad, ruining an image completely. The shadows cast by the
flash can make the subject of the picture look very harsh. To lower
these effects try to take your photos against a dark background, or
even better in the middle of a room with no set background at all. If
you take your photos against a white wall the in-built flash will not
be able to provide results you?Td want. More serious flash units are
able to tilt in different directions. Sometimes it?Ts all that is
needed to fill the shadows.

Serious stuff
For those who wish to take more than family snapshots it is advisable
to purchase a camera with a separate flash unit. There are many types
available with prices from $50-$500. More expensive units provide
better quality, flash intensity and recycle time.

All of the above can appear in photographs using a camera with a
built-in flash, can be improved or completely illuminated by having a
separate flash. This is because those effects are caused by the flash
and the camera lens being positioned too close to each other.

By holding the separate flash unit away from the camera, the harsh
shadows and outline effects can be reduced or completely avoided!

To reduce the effects of red eye with a separate flash unit, putting
the flash away from the subject of the photograph and bouncing the
light of the ceiling or maybe a wall or a photo reflector, still
delivers adequate lighting, but does not result in red eyes in
subjects.

The best way to identify any problems and avoid them is to understand
flash photography. Many photographers around the world spend
countless of hours, trying to perfect their knowledge of lighting.
There are countless of books written on the subject as well. Maybe
you want to become one of Toronto wedding photographers or high-end
Hollywood fashion photographer-the knowledge of light and shadows is
what photography is all about. Perfecting this would open many doors
in the industry and help you to look at the world around you from a
completely different perspective.

In the world of digital professional photography, taking pictures is not as simple as clicking that shutter button. Though digital imaging has made it easier and affordable for photographers, the quality of the pictures would still be questioned. A lot of factors have to be taken into consideration if you want to be successful at professional photography. Light, composition and background affect pictures. The professional photographer knows this so he or she often ends up chasing light to achieve that perfect photo.

A normal digital camera is not enough in this endeavor. A photographer needs to be armed with a professional digital camera to get all the details. It produces the best image quality and has the capacity to operate even when exposed to low light. It has complicated settings that a novice would not understand at first glance. Photographers often learn through trial and error. This is why a professional digital camera comes in handy because it eliminates the need for films that are expensive to print. And when you go by trial and error, you would make a lot of mistakes along the way. With a professional digital camera, you would be able to check the result immediately without printing the picture. You would also be able to capture extremely small subjects even if it’s too far away because of its zoom capacity. The high-end professional digital cameras allow this and you would be able to get every last detail. Fast-moving subjects are also not a problem with a professional digital camera. It has special controls that let you capture the subject. For example, you are at a basketball game. You can’t exactly order the players to stand still while you take a picture.

The great thing about a professional digital camera is it gives you more control on how you want your pictures to come out. It allows you more freedom on how to play with light. You can set how much light can enter for a particular shot or if you just want to get a picture of a silhouette. This eliminates blurs because you fixed your camera at the right setting. It’s all a matter of how you adjust your shutter speed and play with natural light.

Most digital cameras focus automatically so you don’t have a choice if you want to go about this manually. With the professional digital camera, you could fix it to focus on your subject automatically or not. Another advantage is that you could attach different accessories; specialty lenses, waterproof housing and filters. Special filters would emphasize your photos and add effects. They could also neutralize the light if it is too bright or dark.

The only problem with the professional digital camera is its cost. Because of its quality and features, it is justifiably expensive. But you can buy discount goods at your local discount store so this could solve this issue. Even if it is still expensive at the discount store, the price point has been reduced because it is either used or refurbished.

So if you want to take the best photos, buy a professional digital camera. Your investment would pay off when you see the quality of your pictures.
