Digital Camera Revolution

Unlike conventional cameras, the digital camera does not use photographic film. Digital cameras capture a photograph electronically and store them in digital format and in today’s market the digital camera is outselling the 35 mm film camera. Small enough to carry in your pocket, car console or handbag these cameras can often double as a video camera and also record sound.

The beauty of these compact wonders is the ability to check your photo immediately. Instantly can will know if you have captured the shot exactly how you wanted it and you then have the opportunity to take anther if you are not satisfied. Great when you are on holidays or taking a snap of the grandchildren. The unwanted shots can be immediately deleted saving space on the disc. It is also much easier to modify images taken digitally rather than traditional shots. No more red eye!

Unfortunately there are some disadvantages to digital cameras, one being that many have to be charged using electricity instead of batteries also some applications such as the use of infrared light are not available with digital cameras unless specially converted or a special filter used over the lens but this does need a very long exposure. Due to the fact that digital images can be so easily modified, images taken with a digital camera are not readily accepted as court evidence. For the average person, the advantages far outweigh the disadvantages but not everyone sees it that way.

Digital cameras are also now being used for underwater photography. This is achieved by putting a digital camera into a watertight underwater housing much the same as you would use a conventional camera. Although there are some brilliant specially designed cameras for underwater use, using a digital in the watertight housing has the advantage of not limiting the photographer to the amount of shots he can take as would be the case with 35mm film which only has a maximum of 36 exposures.

Many professional photographers do not use digital cameras for most of their work. They have found editing and post processing takes longer than the traditional camera. When traveling, recharging is more difficult and also, if a conventional camera breaks down, as all cameras do from time to time, it is much easier to repair conventional than digital cameras. In saying that, there has been a swing to digital, especially in the area of photojournalism, where getting that all important great shot happens on the spot. The print media is now accepting more and more digitally captured images.

Over the last few years digital cameras have become much more affordable as the demand for these cameras has increased. More and more features are available and combined with the everyday use of computers the general public who can now easily shoot their photos, go home and print them out on their computers. The many benefits of these multi-functional, light and compact cameras are changing the way we capture our memories like never before.

Digital Camera Photos: From Point And Click To Pointillism

First the digital camera was the next big thing in photography. Now thousands of ten year olds are walking around with digital cameras on their cell phones, emailing themselves pictorial records of their lives.

The digital camera has removed most of the science and a lot of the artistry from the art of photography, because anyone who knows how to scroll down the camera menu and correct its settings for the lighting can point, press, and review the resulting digital camera photos in a matter of seconds. Not a roll of film, light meter or darkroom in sight, and many botched digital camera photos can simply be erased and re-shot.

While the convenience and user friendliness of digital cameras has opened the doors to millions of new photographers, those who have been fans of digital camera photos from their beginning have expanded their horizons to include putting the artistry back into the art. What the amazing FX people of the Hollywood motion picture industry can create on the silver screen has its counterpart on the computer screen for those who are willing to learn how to use software to alter their digital camera photos.

While you can purchase the software to rework your digital camera photos, you can also download many very sophisticated software programs from the Internet at no charge. Whatever software you choose, however, should clearly state that it is compatible with both your digital camera and you personal computer.

How To Use Your Digital Camera Photo Editing Software

Once you‘ve installed your software, select one of your digital camera photos which is the same as it was when you transferred it from your camera to your PC. Save it under a new name. By doing this you’ll still have the original photo as you downloaded it, and the copy which you are going to be altering. If you don’t like the way the copy turns out, you can always delete it and start again from scratch with the original. Always give your reworked digital camera photos new names before you save them.

Put the copy of your photo into the digital camera photos editing software, and read the software help if you like. Otherwise you can just begin experimenting. If you don’t like an effect, you don’t have to save it. The digital camera photos editing software will give you the ability to make of your digital camera photos fantastical creations to satisfy your every creative urge.

Digital Camera FX

Are you a nostalgic sort? Try exchanging the colors of your digital camera photos for the sepia tones of yesteryear. Or go for the striking and stark black and white landscapes of Ansel Adams. Transform the clear pixilated surface of your digital camera photos into newsprint graininess. Or the Impressionist paint strokes of Van Gogh. Or the pointillism of Georges Seurat.

Give your digital camera photos the appearance of having been shot through a filter-- Grand Canyon scene done in red or purple; an autumn woodland shot in rust or orange. Make a drop of water into prism with the rainbow effect.

Reshape your digital camera photos with the software cropping feature; turn that rectangular autumn scene into a pumpkin shape; make the picture of your favorite rosebush into a rose. Exaggerate or eliminate shadows and blemishes as you please. Your digital camera photos software is your portal to a visual world where you make up all the rules.

It certainly it beats being a ten year old emailing yourself a pictorial record of your life from your cell phone!

Digital Camera Storage Media

When someone buys a new digital camera for recreational purposes, they rarely look at the type of storage media the camera supports. How important is the storage media, exactly? Well, it's where your pictures are stored, so it must be pretty important! Someone doesn't want to be in a another country before they figure out the camera blinks "Memory Low" in red. A new digital camera usually comes with a means of storage, but the storage media is, most of the time, not sufficient enough to hold the slighest amount of pictures. The average stock digital camera may come with 16MB, 32MB, and maybe even 64MB worth of memory media. A memory card with at least 512MB-1GB storage is highly recommended to replace the stock memory card the camera packaging includes. The most common types of digital camera storage media are CompactFlash, Secure Digital, xD Picture, Memory Stick, MicroDrive, and SmartMedia.

Most of the current digital cameras use CompactFlash cards. The two types of CF cards are Type I and Type II(slightly thicker). The Type II CompactFlash card is also known as MicroDrive, which will be discussed further down this storage media list. SanDisk describes their CF cards as "size of a matchbook and only weighs half an ounce". There is a controller card that allows for faster transfers. These cards are the most popular because of the decent price and the support throughout many digital cameras.

Secure Digital Cards are the smallest digital camera media cards in the storage media market. The cards can store up to 4GB of memory as of now, but new technology will soon increase the max size to 8GB. A high level of protection is guaranteed against illegal copying. This means that Secure Digital Cards offer more data security.

xD Picture Cards can be used in CompactFlash supported cameras with a CompactFlash adapter. The maximum capacity of xD Picture Cards is a gigabyte of space. The cards offer fast read and write capabilities for digital cameras.

Memory Sticks were created by Sony for their Cybershot line of digital cameras. They aren't supported by brands of digital cameras other than Sony which decreases their digital camera's support of Memory Sticks severely. Many of Sony's other products, besides digital cameras, support Memory Sticks. The Playstation Portable(PSP) uses Sony's Memory Sticks as well as Sony's Vaio line.

MicroDrives are the hard drives inside of Type II CompactFlash Cards. They have better value and are better priced than flash memory, but flash memory has more space and storage. You may have heard that hard drive MP3 players fail over time due to their moving parts. The same concept can be applied to these cards because they have moving parts as well. This is why you may have heard that MicroDrives are unreliable and low in quality. Many of them would break due to the mishandling of the card.

SmartMedia cards are being replaced by the new flash card technology. The cards are still available, but the modern digital cameras usually don't support this type of storage media anymore. The card is cheaper than all the other types of storage media mentioned above.

Storage Media for digital cameras is constantly evolving and improving in quality and capacity. Years ago, the maximum storage capacity for an average memory card was 128MB or 256MB at max. They cost way too much, probably 300% more than they cost right now. The prices of digital camera storage media gets lower every year as the technology gets better. The types of storage media provides diversity and choice for the average consumer with a digital camera.

Things You Should Know Before Buying Discount Cameras

Taking photographs has always been considered an enjoyable pastime. Photography is one of the best ways to capture a moment in time. It seems now the world has become obsessed with taking pictures. Everywhere you look there are advertisements for cameras. Probably one of the most significant innovations in the Digital Age has been the digital camera. At one time these cameras had one thing in common with their non-digital counterparts—an expensive price tag. In recent years the cost of digital cameras has dropped considerably; so much so that you can easily purchase a digital camera for less than $200. To find the best deal you will need to do some comparison-shopping. By arming yourself with some information about digital cameras, you will better prepare yourself for buying discount cameras.

As most of the innovations in digital technology, digital cameras are considered more complex than they really are. When you shop for discount cameras, price should not be your only guide. It is a good idea to understand some of the basic features of digital cameras so that you can effectively compare the various models available on the market.

If you’re interested in buying discount cameras, you undoubtedly are familiar with at least one buzzword associated with digital cameras: megapixel. Megapixel, which refers to the number of pixels per one million or how fine an image’s resolution is, is important to consider when buying discount cameras because megapixel directly relates to the image quality you are able to obtain. When you shop for discount cameras you will notice that there are a wide range of megapixels. At one time, a digital camera with 1.3 megapixel was standard and a camera with 5.0 megapixels was considered top-shelf. With the recent introduction of digital cameras with 9.0 megapixels, the standard in megapixels is changing.

Buying a digital camera with the highest number of megapixels is not necessarily the best method of selecting a digital camera. Since megapixels relate to an image’s resolution, you should first determine your plans for the digital camera. If you want simply to take images for personal use, a median number of megapixels such as 3.5 may be sufficient. If on the other hand you intend to enlarge and crop images, you may want to shop for digital cameras with a higher number of megapixels.

The number of megapixels that a camera uses is the primary selling point for digital cameras. However, it is the additional features that will have the greatest effect on price. Optional features that you may want to consider include video recording capabilities, an optical zoom lens, and a histogram. Most cameras include a zoom lens, but it is usually a digital zoom lens. This type of lens only appears to enlarge the image. An optical zoom lens is an ideal option if you will use your digital camera to shoot distant objects. Creating a digital movie is another popular option. If you want a digital camera with this feature, be sure to note the maximum recording time. A handy feature that is not used often, but is very handy if you are serious about digital photography is histogram. Once you snap an image you can use the histogram option to analyze the exposure. If an image is too bright or too dark you can reshoot the image.

Find the Best Digital Camera for Your Needs and Maximum Enjoyment

Digital Cameras have become a common site wherever you go. If you're getting ready to purchase your first digital camera, or maybe you're looking to replace one you already have, it is best to familiarize yourself with the knowledge of what makes one digital camera different from another and choose the one that is right for you. In this article we'll cover one of the most significant factors in picture quality. This is the “digital film.”

Just like with a film camera, the digital camera has a lens which brings light into focus on a bed of light sensitive material. In the digital camera, that light sensitive material is a circuit bed called a “CCD.” The CCD plays the same role as film in a film camera and the lens allows light to fall onto the CCD which is then converted into a digital image. The quality of the lens can make a significant difference in the clarity of that image. Very cheap digital cameras may even use a piece of plastic as the lens, which will usually have an uneven surface and light transmission. This will be noticeable in the picture but may not be an issue for a security camera or a web cam. Better quality digital cameras will have ground-glass lens and high-end digital cameras will even have interchangeable lenses as do high-end film cameras. The lens still plays the important role of bringing light clearly to the CCD surface for a distortion free picture.

A CCD also provides an interesting advantage to the digital camera. It is possible to automatically adjust light sensitivity to improve contrast, shoot in dim light, or even take black and white, sepia or infrared and ultraviolet light pictures with the touch of a button. Because any of these images are stored as the same data on the memory card, a digital camera can offer unsurpassed versatility without the need to change film types. Not all digital cameras have these features built in, but they are options you may see in some cameras. While the possibilities are cool, ask yourself if you that is a feature you need in a digital camera.

With digital cameras, CCD is a grid of light sensitive points which capture the image for conversion into a digital image. The number of points on the CCD is measured in terms of “mega pixels.” The mega pixel rating is a completely new bit of terminology and is unique to the digital camera. The mega pixel rating is a measure of the resolution of the camera, or its ability to store details of am image. For example, a digital camera with a maximum resolution of 1280 by 768 pixels (dots) comes out to a total of 983,040 pixels with which to describe the digital image. As each mega pixel represents one million pixels, we can see this isn't even one mega pixel. Some digital cameras have mega pixel ratings at 5.1 and even 7.1 mega pixels. What does this mean to you? The more pixels the more detail stored. If the image is going to be viewed on a screen or a TV, this isn't very meaningful because video displays have resolutions which are usually well below one mega pixel. However, when printing on a high quality photo printer, the difference between a 3 mega pixel digital camera and a 5 mega pixel digital camera can be very obvious.

Some people will try to evaluate a mega pixel rating by how large a print can be made from the digital camera's image. The truth is that any digital image can be printed to any size. The real issue is what it looks like. Most people print their film to 4x6 prints and many are now doing the same with their digital cameras. Ask to see printed samples of pictures which are like the type you would normally take and compare the same prints between different cameras. Many stores will try to dazzle you with colorful still life images of piles of multi-colored fruits and hot air balloons. Do you take pictures like that? Probably not, so perhaps they're not the best images to be scrutinizing. If you take pictures of friends standing around, use each camera to take pictures of people standing around. Then use a demonstration printer at the store to make prints and look at the results. Do you see little dots in the middle of solid colors? Does the image look like it was taken with a poor quality film camera? Don't seek out the digital camera that happens to take perfect pictures in a perfect setting, contrived by the marketing department of the digital camera's manufacturer. Look for the digital camera that takes pictures you like in the settings in which you most commonly find yourself.

Another issue to consider is that some digital cameras are designed for “point and click” use while other cameras are designed with lots of settings which must be manipulated for optimal results. In my personal experience, I have found that Kodak makes digital cameras which are ideally suited for simple “point and click” use and consistently take great looking pictures in a wide variety of settings. I have also personally found that digital cameras from Nikon work best when you set them to “manual” and do not rely on the automatic settings. This seems to be true of their film cameras as well. Does this make one digital camera better than another? Only if one fits your needs and skills, and the other does not.

There are many magazines available on digital cameras today. Most recognize these differences in digital camera quality, based on needs and intended use of the owner. Before buying your new digital camera, pick up a few of these magazines and familiarize yourself with the latest reviews. Remember that the pros and cons are still written “through the lens” of the reviewer. If you see a negative about a digital camera that you otherwise like, ask yourself if that negative is meaningful to your needs. Next ask yourself if that negative might be meaningful to your needs as you become more experienced. If the answer is yes, ask yourself if you would still be using that camera as a more experienced photographer in the future or would you perhaps sell it and buy an entirely new digital camera? It's unlikely that the digital camera you buy today is going to be the only one you'll ever have. Buy the digital camera that most reasonably meets your needs and how you normally plan to take pictures.

Memory cards and battery life are also consideration factors which will be covered in other articles. For now, I hope this information has taught you more about the workings of a digital camera and some of the factors to consider when choosing one. Take your time and learn a bit about digital cameras before your purchase. Sure, it's not like buying a car, but photography is a very personal experience and the right digital camera will truly make a difference in your enjoyment of capturing the moment with digital photography.
