Battery Chargers For Digital Cameras

Battery chargers allow your digital camera to keep functioning till you get that perfect shot; because digital cameras tend to be one of the most demanding electronic instruments on battery capacity, battery chargers for digital cameras are in high demand.

In order to get the most out of your batteries, and your digital camera, you not only want to have batteries with high capacity NiMH cells, you also need to have a good-quality battery charger. Some battery chargers for digital cameras can’t handle the high capacity NiMH cells within the battery and significantly undercharge it. Other battery chargers actually overcharge and eventually damage the batteries. Choosing the best battery charger for your digital camera will allow you to get optimum use from your batteries and your camera.

Advancements in Battery Chargers for Digital Cameras

There have been significant advancements in digital cameras over the past three years. At one time, the battery charger C-204F was believed to be the most efficient battery charger. Recent advancements in technology have improved the Maha Powerex C-204W, and in test results have proven to be more efficient in ‘topping off’ batteries. There have been a number of improvements to the Maha C-240W’s, making these the most popular battery chargers for digital cameras.

A unique feature with the Maha C-240W is its sophisticated algorithm, which allows it to detect alkaline batteries, which cannot be recharged. Although alkaline batteries can be used in digital cameras, they have a much shorter life, and prove to be very expensive. Although the 204F offered support for NiCd cells, the Maha Powerex C-204W only supports NiMH batteries.

Quality Testing for Battery Chargers for Digital Cameras

When testing the quality of battery chargers for digital cameras it was found that when the quick-charging cycle was completed, many of the fast chargers were unable to completely fill the battery. In order to compensate, some chargers switch to a ‘trickle off’ mode once the fast charge is complete, so that the charger can ‘top off’ the batteries. This is found to be best used when leaving the batteries to charge overnight. But even then, the C-240F was unable to charge the up to the last 5% capacity of the battery.

An important factor to consider in battery chargers for digital cameras is the amount of heat and distress the charger subjects the battery to. A battery charger that consistently overheats batteries will prematurely exhaust the batteries and shorten its life.

Tests have found that the Maha Powerex C-240W is a smart battery charger. Like the 204F, the 204W features two separate charging circuits that enable you to charge either two or four batteries simultaneously. This becomes increasingly important as many of today’s digital cameras run on two AA batteries, and in order to get the most out of your batteries, you need to charge them in the same groups they are used in. This keeps the battery charger from overcharging or undercharging battery cells that have diverse usage patterns.

The Maha Powerex C-240W battery charger is reasonably priced at approximately $30. Some suppliers offer the C-240W within a kit that also comes with four AA Powerex cells at a discounted price. It’s important to keep the quality and the price in mind when choosing battery chargers for digital cameras.

Basics of the Digital camera

Like most things in life when your experiencing something for the first time you are often unsure how to go about it. The same can be true when buying your first digital camera. You will undoubtedly be inundated with facts, figure and more jargon than you know what to do with. We will attempt in this article to help you along with some of the jargon and show you what to look for when buying a digital camera. Some of the feature may not interest you unless you need your camera to perform specific tasks, however its always worth knowing exactly what you are buying so you can pick a good deal when you see one.

<b>Megapixels</b>

The resolution of a camera is measured and advertised in megapixels. The idea behind this figure is the number of pixels that the camera has to take an image with. In this case the higher the number the better quality of picture you will be able to take. For example if you purchase a camera that has a resolution of 4 Megapixels, pictures that you take with that camera will be able to take images made up of 4 million pixels. Its obvious when you think about that a camera with a 2 megapixel resolution will not create as image as crisp or as detailed as the 4 megapixel one.

If you often print out your images on your PC or have them sent away to be printed then the megapixel rating of your camera can be very important to you. Higher megapixels on your camera will allow you to make prints larger in size while still keeping the quality. If you try to print a picture too large than what you camera was designed for then the image drastically loses quality.

The last thing to know about megapixels is the higher the resolution you take pictures in the more space on your memory card will be taken up. A picture taken on a 4 megapixel camera will need twice as much space on a memory card as a picture taken on a 2 megapixel camera. Be sure if you want quality pictures have enough memory on your camera to back it up., Either that or have spare media cards to plug in once your space has been used up.

<b>Digital Zoom and Optical Zoom</b>

No doubt when you are buying a camera you will want some sort of zoom function to take those in the distance shots. This is a troublesome area for some first time buyers. There are two types of zoom on the market for digital cameras. Digital Zoom and Optical Zoom. The only one that really matters is Optical zoom, this is true a true zoom function that brings the objects closer to you using the optics of the camera. Digital Zoom is like using the zoom function on an image editing software package. It enlarges a section of the image so it looks as if its closer to you.

Anything you can do with digital zoom you can do with a photo editing package so don't splash too much money on a camera with digital zoom only. Sometimes you will also so "total zoom" advertised this means the number that is quoted here is the optical zooms magnification added to the digital zooms magnification. Try to find out the magnification level of the optical zoom alone for the true value of the camera.

<b>Aperture Size</b>

We may be going a little further here than some of you would like to care about but bear with us as the aperture size can make a big impact on your pictures. The size of the aperture determines exactly how much light is let into the camera when your picture is taken. Think of the aperture like the iris of your eye. No big deal you may think, however having more light allows you take better pictures in a variety of lighting condition, cloudy days is a perfect example.
With a large enough aperture you would be less likely to need the flash, personally I don't like to use the flash function, the artificial flash of light does not always do justice to the picture you are trying to take. Also effects like red eye are also common.

<b>Shutter Speed</b>

Great effects can be made to images using a variety of shutter speeds. The thing to look for when buying a decent digital camera in terms of shutter speeds is the broadest range you can find. This will give you the best chance of manipulating the picture the way you want it. Combined with a pro-active aperture the shutter speed can make pictures come to life or freeze images in an instant.

This technique is great when you want to take moving objects exactly how they look as if they were still. Setting the shutter speed on a slower setting gives more exposure to the CCD (charge coupled device - the digital equivalent of film). The effect is that the picture almost seems to run. Moving objects are slightly blurred. You may think this is a bad thing but take an example of running water leaving the shutter speed on for longer will soften the image creating a pleasing image to the eye much like the way a waterfall appears in real life.

You can take digital photography to the extreme with a camera that has a very wide range of shutter speeds. With an incredibly slow shutter speed, you can have a long exposure of light to the CCD and hence receive like the famous traffic scenes where the headlights blend into each other into a constant stream.

<b>Storage Media</b>

Digital Cameras come with a slot for a variety of media cards. Check when you buy your camera what type of storage media it requires. There are several popular types including Smart Media, compact flash and xD picture cards. As long as you know what type your is you should be able to safely by the correct type. Always ask at your local store if you are unsure. If you give them your make and model they should be able to point you in the right direction.

The size of the media card you choose depends on your budget but get as much as you can afford. More memory means that you don't have to change media cards, and you will be able to take pictures in the highest quality all the time. You will soon learn the benefits of having plenty storage space when you start to use your camera regularly.

The good thing about cameras media is that its just like a film if you do run out you can simply insert another one if you have one with you. It can be a bit of a pain when downloading your pictures to your PC but much less more of a pain than having to delete some picture because you have run of space on your media card.

A Guide to Disposable Digital Cameras

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

A Few Helpful Tips For Choosing A Digital Camera

Digital cameras are different from regular cameras because they have a computer built into them. This means that you can later transfer the images to your pc and play around with size and definition. Digital cameras have been around for a while now and the prices are just about on a par with the prices of a good regular camera.

If you are looking for a digital camera, there is plenty to choose from – with prices that should suit most budgets. Some digital cameras are better than others but it is a good idea to do your homework before handing over the money. If you don’t, you could end up with a camera that does not suit your needs.

What advertisers call the perfect camera may not be perfect for you. In addition to this, advertisers are trying to sell a product and what they call perfect today may not be tomorrow. You, on the other hand, want a camera that does what you need it to do and that will last for some time. Advertisers are not really concerned with people’s particular needs, just with popularizing a product.

Before you set out to buy a camera, it’s a good idea to have some understanding of the terms you might come across. For example, you may hear the retailer mention pixels and not know what they are.  Pixels are the dots that make up the picture. Thousands of these dots are known as megapixels, the more megapixels you get, the sharper the picture you end up with.

Megapixels can also determine the price of a camera, the more you have, the more expensive the camera will be. A lot depends on what you want the camera for. If all you want to do is take family photos and email them to friends and relatives, a normal four megapixel camera should be just fine. If you want to use it professionally, you may need something with more pixels.

You might also want to consider size when buying a digital camera. Now days, you don’t have to buy large cameras – some are so small they will fit into a shirt pocket. However, size is also affected by price. It takes greater technological know-how to make a small camera than it does to make a regular sized one. Most people who take family photos do quite well with a regular one.

The information above should give you some idea of the general things to look for in a digital camera. Now it is up to you to decide which camera you think is the best for your particular needs.

Once you have thought about those aspects, you should have an idea of the kind of camera you want and it should enable you to look at the lists of digital cameras online or in the stores and short-list any suitable models.

You should then try to look and, if possible, handle the actual cameras, either in store or, better yet, if people you know already own them, you are likely to get better answers to any questions you may have.

Then try to find examples of any pictures taken to see the quality and whether it meets your expectations.

A Beginners Guide To Choosing A Digital Camera

Digital photography is no longer a ‘new thing’. Digital photography has flourished of late and for good reason. Gone are the days when taking your holiday snaps required buying a film, taking pictures in the hope that at least half would develop and then tripping down top the processor after your holiday or sightseeing. Now there is a multitude of options from the expensive to inexpensive that allow you to take your pictures, view the results and decide which pictures to save for future printing on your home PC or delete as unsatisfactory. All the former big boys in the camera market, such as Canon, Kodak, Nikon, Olympus and Fuji now have digital cameras to suit every pocket and every use. There are even numerous smaller companies building digital cameras to suit this ever growing market. For a first time buyer the choice can be so bewildering, so how do you choose which camera will suit you?

The basics of choosing a digital camera are to know your budget, know what type of pictures you want to take and how you intend to use the pictures.

For the beginner setting a budget on your camera purchase will soon cut down the choice to a manageable level. Ask yourself, are you just gong to take the odd holiday snap if a one off picture opportunity comes up or are you the type who likes to fully document each holiday you have, maybe you’re a habitual holiday snapper from pre digital times? If you’re the type who only takes a picture on holiday if you see something truly inspiring or just to document that you did attend then go for the lower price end. You should be able to pick up something useable for $50. If you document your holidays and most of the sights you see regularly and have maybe owned a camera for years then splash out toward the higher end of the basic models, think in terms of a $200 investment.

Once you have established your budget consider the type of pictures you’ll be taking. Are you likely to be taking pictures everywhere you go? Consider the weight and size of the camera you need. Are you likely to be taking pictures of friends and relatives on location or do you have an eye for the picturesque panoramas? Maybe consider a zoom lense, for panoramas go optical for family shots a digital zoom with flash may suffice. Are you a habitual snapper when the cameras in your hand or an opportunist clicker? Consider the size of memory you’ll require. The opportunist may not require huge lumps of memory but a habitual snapper may be different. Think about battery life. If your going to take a few shots a day you’ll need a better battery life than if you take the odd snap.

Once you have chosen the best combination of size, weight, memory, battery life and zoom for your uses, consider how you will use your pictures. If you need to print large pictures off your computer beware the more megapixels (resolution) you have the better. It is a sure thing that the higher the megapixels the more expensive the camera, so leave this choice till last. For a beginner spending your budget on a camera based on megapixels initially will lead to a poor choice with a camera that does have the other characteristics to suit your purposes. If you generally print off the more traditional photo sizes for an album do not be to concerned with the number of megapixels, most base model digital cameras will give you an adequate print.

percent of people buy the wrong digital camera

When I teach a new class learning digital photography, over 75% of the students turn up with the camera the salesman suggested.

Guess what? They soon find out that it’s the wrong one for them. This can be a very expensive mistake. So the big questions are what is the right one for me and how do I know which is best for me.

One of the first things that you want to know about the camera that the salesman is trying to sell you is as follows -&#8232;How long does the camera take to turn on and be ready to take the shot? In the consumer market this can range between 1 to 5 seconds most being towards the 3 seconds mark. &#8232;How long does the camera take to focus on the subject? (Not to take the picture) most cameras take between 1 to 3 seconds most at around the 1-second mark. How long does the camera take to actually take the photo after you have pushed the shutter button completely? Again, most cameras take between 1to 3 seconds this is called shutter lag time. Now you can see to take a photo can take up to 5 seconds just to turn on and up to another 3 seconds to focus in and the up to another 3 seconds just to actually take the photo.

In a cheaper camera, but not necessarily cheaper it can be up to 9 seconds to take a photo from the camera turned off. You may say “yes but I will leave my camera on” ok that’s fine, but you may still have a lag time of up to 3 seconds just to take a photo. Just imagine how annoying it will be now that you have purchased your new digital camera costing you around $400 - $500 to find that you just can’t catch your child blowing out the candles because your new camera at the critical time of blowing the candles out took 1 second to focus and a further 2 seconds to take the photo. What was the result? A child sitting in front of a cake with black smoldering candles.

Can you set the white balance on your camera? Just what is the white balance?

About 60% of digital cameras don’t have this adjustment, you must buy one that can be set manually, not just one that has an “auto white balance” as they are not as good as they advertise.

Does your camera have different exposure modes?

Exposure modes are simply where does the camera take a light reading? The cheaper cameras just do an all over reading which can be very limiting to say the least. A good camera will have a “spot”, “centre weighted” and “matrix” metering system, which allows you to take great photos in any light situation.

When buying a digital camera, buy it for the fact that it’s a camera not a video camera as well. One student showed me all the features her camera had and that’s why it was more expensive – the only thing that it didn’t do well was take still pictures!

You can get so much out of your new digital camera! you just have to put some time in for learning how to use it properly and how to take better pictures – remember no one will ever want to look at a poor quality photo twice!

If you want to take really great pictures that will be in your family for years put in a little effort with your new digital camera.

Materials And Technologies That Just Might Eliminate Digital Camera Shutter Delay

Bob pushed the shutter release button and…NOTHING HAPPENED. The football passed into his son's hands and the actual photo he took was one of a cheerleader's pom-pom. Bob missed the touchdown too. He resisted an insane urge to slam the camera to the ground and jump on it.

This was his first digital camera, and Bob had just experienced an unpleasant surprise. He had used film cameras all his life, but when his Yashica went into the shop a friend loaned him a digital camera. He naively decided to take some action shots and discovered the most maddening "feature" of digital cameras – the shutter delay.

MADDENING AND FRUSTRATING

Articles on this subject have attributed shutter delay to:

1. The camera's focus system

2. The time it takes the camera to digitally process the image

3. Reaction time of the photographer

Numbers one and three are lag times that most people using digital cameras are accustomed to. Most have used a film camera and know it needs a few milliseconds to focus.

The no-brainer solution is to reduce the aperture of the lens to increase depth of field, or aim the camera at the object you wish to be in focus and depress the shutter button half way in order to "tell" the camera what to focus on, then move the camera to center the image and depress it the rest of the way.

As far as human reaction time, well, it hasn't really changed much for users of film cameras, and people experienced in taking action shots usually get what they want.

So let's look at number 2, the time it takes to process the picture.

TIME TO DO THE PROCESSING

Processing the picture (so the camera can be ready for the next one) comes in several steps to move it from the image sensor to flash card storage:
