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.

For many, digital photography is a breath of fresh air, but be wary – believing our landscape images will be superior could be a serious blunder.

Having lost count of the number of people who have asked me: have you gone digital? I am always left wondering why it’s such a much-asked question. The camera is only a tool in which a photographer creates an image. His personal ability to create a unique image remains the same.

For many forms of photography, digital has long held obvious advantages, but for landscapes the resolution necessary to make larger prints just wasn’t available. But things have changed and digital cameras are fast becoming the tools that most pros use.

Modern digital cameras are perfectly capably of matching the 35 mm film – the format which most landscape photographers begin with. But can they really match the large format film cameras? This is probably the greatest question that all photographers face.

Instant LCD feedback is digitals greatest gift and this enables the photographer to check exposure and composition of their image in the blink of an eye. While this is a big advantage, the hours spent in front of the computer processing the raw images have to be a hindrance. A landscape photographers time is best spent behind a camera not in front of a computer.

The pros and cons of digital photography will remain an issue for some time. At the end of the day a digital camera won’t make a photographers images better. The same values we apply in our photography should remain regardless of which camera we use.

Good photography remains as elusive and as enticing as it ever was; going digital doesn’t change this or make getting good images any easier. It brings technical advantages, and plenty of them, but the majority of photographic techniques never change. Good landscape images come from the photographer’s personal ability, not the ability of a camera. The camera helps, but the creative eye remains the same.

As a landscape photographer I am still hesitant to embrace digital photography and all the qualities that digital has brought to other professionals in different photography fields.

There are a few simple reasons that I still use a film camera:
The authenticity of my images could be questioned if I used a digital camera. It is often assumed that great digital images have been manipulated.
Too much time is spent in front of a computer.
Slide film produce stronger colours than a digital camera.

There are many advantages for changing to digital but I’m going to stick with film; for the time-being that is. With time film cameras will be a thing of the past and all our images will be exchanged for the pixels. But, be wary – believing our work will be superior would be falling into a great trap. For me size matters, the larger I can print an image the better. John Pawletthttp://www.articlesbase.com/gps-articles/digital-or-film-camera-89105.html

Remember the good old days, when buying a digital camera meant choosing between two or three models? That was the year 1995, and there were literally only three digital cameras which had been introduced for the consumer level market-the Apple Quicktake 100, the Kodak DC40, and the Casio QV-11. Back then, it was easy to get information about each camera and decide which would work best for you. Well, those days are definitely gone. Now, if you want a new digital camera you’ll have to sort through hundreds of different models and make countless decisions, like how many megapixels you’d like your camera to have, what type of media you want your camera to store your images on, and what levels of digital and optical zoom you’ll need…not easy tasks, especially if like me you’re not sure what a megapixel is.

I recently decided that my old film camera needed an update and made the momentous decision to buy my first digital camera. Though I’ve always been one of those people who shies away from new technology, friends and family had been telling me for years that it was time to go digital. According to them, the benefits of having a digital camera far outweighed my fear of high-tech gadgets. They told me that I could save a fortune on film and developing costs, that I could view my pictures instantly, edit them on my own computer, and print only the ones I wanted. So, I decided it was time to jump on the technology bandwagon and find myself a simple little digital camera.

Easier said than done.

Several disappointing trips to the electronics stores in my area left me confused and camera-less. I’ve never been intimidated by salespeople, but the electronics stores were completely overwhelming. I had no idea there were so many digital cameras on the market today and had trouble even understanding what the salespeople were talking about when they pitched their products! Megapixels, CF, CCD, dpi, MMC…does anyone know what these terms mean? Finally I decided to try my luck on the Internet, where I could at least conduct the search on my terms, without hovering salespeople, in the comfort of my own home.

I tried the big online shopping sites first, but found most of them even more overwhelming and confusing than the stores. I’ve been using the Internet for years, but I had difficulty finding my way around most of these sites. Not only that, but there were even more digital cameras to choose from than in the stores! I hadn’t thought it possible. I needed guidance…unbiased guidance in language I could understand.

Finally, I came across a new website called www.techselector.com. The site promised to help me find the right product every time-in four simple steps. After my previous experiences I had my doubts about this, but decided to give it a shot. I was instructed first to choose the category of product I was looking for – digital cameras – and then to complete a short multiple choice questionnaire. I expected the questionnaire to be tedious, full of terms I wouldn’t understand, but it wasn’t. It was simple, and any technical terms were explained to me in everyday language. After I completed the questionnaire, the site generated my own personal Product Report, which listed the best products for me based on my questionnaire answers. The Report was easy to understand – I could see pictures of the products, view detailed specifications sheets, and compare different products. After a few minutes of reading through my Product Report, I made a decision and with the click of a button, I purchased my first digital camera.

Sure it’s not 1995 anymore and there are considerably more than three digital cameras to choose from, but the cameras today have amazing features we couldn’t have even imagined back then. Don’t let the overwhelming selection of available models and the confusing technical jargon deter you from getting a great new camera-or any other new high-tech gadget. Techselector.com features a number of different product categories, tech guides, and glossaries which can help you understand all the terms and features. Best of all, the site can help you to sort through the different products and find the ones that will suit you best – quickly and easily. My new digital camera arrived a few weeks ago, and already I’ve almost forgotten what it was like to buy film. Had I known it would be so easy to find the perfect digital camera for me, I’d have done it a long time ago.

Before getting to see how a digital camera works, let’s begin by saying that a digital camera differs from a classical one primary through its storage capabilities. Imagine that using your old classic 35 mm camera you could make “n” pictures (for example 36) on a film before having to stop making pictures and change the film.

This inconvenient is no more present with digital cameras because you have so much space available that you could do several hundred pictures before having to empty your card and if this thing is annoying imagine a portable drive with so much space that you even forget the meaning of “spaceless”. Here is how a digital camera works.

Until now we concluded that the biggest difference between classical cameras and digital ones is “available space” but is this all? The answer is a simple NO; I suppose you heard many times the word mega pixel when speaking of digital camera, but what is it? A digital camera works on the basis of stimuli that an incorporated sensor receives.

In a digital camera the light excites a digital sensor which is a very small computer; this sensor is composed of millions of tiny sensors called “pixel”, a pixel means “picture elements”. It is on due to pixel structure that a digital camera works.

These many small sensors make up a sort of table that has a vertical and horizontal length, so if I say that my camera has “N pixels width * M pixels height = K” this number K is the “Megapixel that we’ve heard so many people speak about”. So is this all the mechanism that shows how a digital camera works?

So mega pixels are made of millions of small dots, so more pixels means more mega pixels, hence means a higher quality picture, but a more expensive camera. After the light has reached the sensor it goes through several filters until it becomes a digital signal. This doesn’t tell us all about how a digital camera works.

Another set of filters is applied for white balance, color and aliasing. At the end of this process the image is made as small as possible with a technique of “erasing” unnecessary pixels. Next the image gets into the buffer, and when the buffer has completed loading the image it writes it on an external memory like a card. Basically this is the secret of how a digital camera works.

Now I will tell you a few words about the “legendary” zoom that usually makes the difference between a cheep and an expensive camera. The digital zoom is a “fake” zoom because it simply enlarges the pixels that make up the photo so … you can’t imagine the result.

How does a digital camera zoom work? An optical zoom is a different thing, because you can change the “field of view” for widening out for a landscape photo or zoom on for a nice portrait. All this is realized by moving the lens elements to change the focal length. So if you like to take nice photos look for the optical zoom, remember that the digital one is just for the seller to tell you that it’s not such a bad deal to buy a camera that has a zoom of 5. Always ask and test how the digital camera works. James Dawsonhttp://www.articlesbase.com/computers-articles/how-does-a-digital-camera-work-98143.html
