Everything Digital Cameras

If children love hide and seek and squeal in delight when they find who or what they are looking for, imagine how enraptured they will be to be able to peep through a little hole on a camera and capture what they see for in a photograph.

A digital camera, with all the convenience of a digital device but with child-friendly features, has made children’s digital camera a hit. Parents and teachers who were included in a survey to assess the popularity of the camera gave it rave reviews.

It has instructions for its use written out clearly and simply enough for a child to figure out by themselves alone. And even though it’s meant for a child, its abilities are no child’s play. It gives top quality images on a 1 ½ inch full color LCD when they are being viewed on a computer screen and when they are being printed.

It has also take all the jostling for it and frequent use children will put it through thanks to its durability, including being able to take five drops from a height of five meters. It’s no doll when it comes to memory too. It can store up to a generous 500 photos with a 2MP resolution and it can also store up to eight minutes of a video clip. It also takes a 16 GB SD card.

Another feature on the camera is AV cables to plug in into a television so one can view photographers or video clips. It comes with software included that is compatible with Windows, Mac, XP and Vista. To add even more fun to it, the children’s digital camera lets them play around with photos they’ve taken, putting them in frames, making them into stamps, altering facial expressions and adding kaleidoscopic effects. It will make for fun times using it and more viewing and playing around with images.

A digital camera captures images in a digital format, unlike a conventional camera, which captures images using a photographic film.

History:

Using a mosaic photosensor, Eugene F. Lally of the Jet Propulsion Laboratory first showed how still photos could be produced in a digital domain. An engineer at Eastman Kodak, Steve Sasson, used solid-state CCD chips to build a prototype digital camera having a resolution of 0.01 megapixel, and recorded black and white digital images to a magnetic cassette tape. With this prototype model, Steve took the first image in December of 1975 taking 23 seconds to capture it.

In 1988, Fuji DS-1P became the first digital camera that captured images as a computerized file. However, the camera never entered the U.S. market. In 1991, Kodak DCS-100 was the first commercially available digital camera, which used a 1.3 megapixel sensor. With the advancement of technology, modern digital cameras have become multifunctional and are now capable of capturing audio/video and still photographs.

Benefits:

1 – You get superior image quality. Digital cameras can offer good to excellent image resolution.

2 – You get a fair price. A digital camera is reasonably priced and is affordable.

3 – You can transfer the pictures to your laptop. You can easily connect the digital camera to your laptop and transfer the pictures in your hard disk.

4 – You can print in large sizes. Due to its high resolution, pictures can be printed in large sizes by any plotter.

5 – You can email the pictures to your friends. You can send the pictures by email to your loved ones.

6 – You can store the images in CDs or hard disk. Once the pictures are transferred from digital camera to the computer, permanent storage on a CD or hard disk is possible.

7 – You can take the camera in your pocket while you travel. The small size of the digital camera makes traveling with it easy and a pleasure.

8 – You can move in close to your subject. Zoom lenses offer close-ups of your subject with sharp focus. You can take very good close-ups of flowers, bugs, stamps, coins, etc.

9 – You can rework the image in a computer. Any photo editing software can rework the images taken.

10 – You can take good pictures even in low-light situations. Due to flexible over sensitivity or ISO equivalents, digital cameras can easily take detailed pictures even in low-light conditions.

11 – You can take quality still photos of moving objects. Sports and fashion photography can be easily accomplished due to the fast burst rate of digital cameras.

12 – You save money. There is no need of buying photographic films, developing them into negatives and positives. Moreover, the batteries are usually rechargeable lithium-ion batteries, which last a long time.

13 – You can choose as per your needs and fancy. Many models are available like standard digital camera, underwater digital camera, waterproof digital camera, compact digital camera, and the professional digital camera.

Storage Media:

Digital cameras use memory to capture and store images. Some of the storages media used are onboard flash memory, 3.5″ floppy disks, video floppy disk, PCMCIA hard drives, CD or DVD, CompactFlash memory cards, Microdrives, Memory Stick, SD/MMC, MiniSD Card, MicroSD Card, XD-Picture Card, SmartMedia, and FP Memory.

Power:

Digital cameras consume a lot of power, which is supplied by powerful, small in size batteries. Batteries are broadly divided into two groups, namely, off-the-shelf and proprietary. Off-the-shelf batteries are like AA, CR2, CR-V3, AAA, and RCR-V3. They are lithium-ion (Li-Ion) or Nickel metal hydride (NiMH) batteries. Standard AA non-rechargeable alkaline batteries either do not work or work for only a very short time in most cameras.

Proprietary batteries are built as per the manufacturer`s custom specifications and are usually available as aftermarket replacement parts. Generally, lithium ion batteries are widely used as proprietary batteries for digital cameras.

When looking for a digital camera for a child, what things should you consider? The age of the child, his or her knowledge of cameras and photography, and of course, your budget all factor into your purchase. The various kinds of digital cameras available can make it difficult to choose the right one, especially if you’re shopping for a child. The following guidelines will help you in your search for the right digital camera for your child.

Video capabilities are standard in almost every digital camera these days, take this into consideration as you shop. Nowadays almost all digital cameras have a video function. Your older children will of course appreciate this function more than a smaller child might. Kids who develop a strong interest in video will eventually need a camcorder, but digital cameras can at least introduce them to this exciting field. With the availability of video technology on computers, cell phones etc your kids are exposed at an early age to video streaming. So, when choosing digital cameras for kids you may want one with video capacity.

The toy section is usually where parents start out looking for kids cameras. If you are shopping for a very young child this might work but not for the older ones. With all of the technological advances our kids are exposed to at early ages it’s not a big surprise that toys just don’t keep their interest for long. One other factor to consider is the price, toys are no longer less expensive than real entry level cameras. It may please you to know that you can find these entry level cameras for less than twenty dollars online as well as in discount retail stores. You’ll save some time and money by skipping the toy stage all together and getting them a real one they’ll love.

You will also need to find a camera that is sturdy and durable when shopping for a child. Regardless of their nature, kids tend to be hard on their things. The best kind of digital camera to get is one that is made to take a certain amount of abuse. In case of pool accidents, you should also consider getting one that is waterproof. While you want to encourage your kids to be responsible with their possessions, you can’t expect them to always be careful and paying attention. For this reason, it’s important to get a camera that will stand up to some abuse from the child.

Digital cameras can be a great gift for a child. Learning how to take pictures will not only teach them about technology but they’ll become more observant of the world around them. Keeping these tips in mind will make your search for the best digital camera for your child easier. Just remember that they don’t need the most advanced camera available.

Why is so difficult for camera companies to come up with one good all around digital camera that’s perfect for all occasions? I suppose it’s not really in their best interests to encourage consumers to only own one perfect camera, when they can sell them several. If I were more of a conspiracy theory advocate, I’d suggest they do it on purpose. But, I’m not, and I do believe there are other factors at work here. With all that being said, it doesn’t mean we can at least try to find the most likely candidate for best all around digital camera.

The three most distinguishable features or dividing factors when it comes to digital cameras are size, ease of use, and image quality. To lesser and greater degrees, these traits seem to be mutually exclusive when it comes to camera design and build.

Smaller sized camera designs are very portable, but usually affect ease of use and image quality in negative ways. The smaller a camera is, the smaller the controls are, which makes them harder to use. Single control buttons and wheels are often used for multiple functions which can increase user confusion. Smaller cameras often mean, that features like viewfinders get left off in the effort to add bigger LCD screens. Smaller often means zoom lenses are less powerful, and overall lens quality suffers. The most successful small sized cameras I like are the Canon SD1000 Digital Elph, and the Olympus Stylus 790SW.

Ease of use usually means lots of auto settings, which is great for newbie photographers, as little skill is required to snap a picture. But, it also means camera designers are forced to compromise on default settings that are OK for most pictures, but not great for all pictures. Factory set defaults will have to do until cameras become smart enough to detect all the nuances of a particular shot regarding lighting, color, and artistic intention. The Canon Powershot A570IS is one of the better cameras in terms of simplifying things at a reasonable price.

The ultimate in image quality usually means big bulky SLR cameras with a case load of lenses and controlled lighting for different types of shooting environments. SLR photography also involves micro managing of all the various camera settings such as aperture, ISO settings, white balance, f-stop and so on. You really have to know what your doing. The Canon Rebel XTi Digital SLR, or the Nikon D40 are good cameras in this category that don’t break the bank.

A digital camera produces excellent photographs. For many years however, professional photographers have discussed the drawbacks to the digital camera from the perspective of image quality which does not always match that available through a traditional 35mm film camera. The convenience afforded by going digital however far outweighs the minor loss in perceptible quality for most consumers.

For millions of potential camera shoppers, choosing the smallest, lightest camera is most important while others may wish to hold down costs or only share photos online where image quality is limited anyway. For these and other shoppers, finding and paying for a more costly camera may be unnecessary. But for those who strive to capture images that record the most accurate and color correct images, there are choices they can make during the shopping process that can help to assure they end up with equipment that will be capable of producing outstanding images.

The primary decision is not about megapixels; or at least not entirely. A digital camera with 10 megapixels does not necessarily produce a better image than a camera with only 6 megapixels. Megapixels are important and a camera must have enough of them to provide adequate image information for the size print being produced so that there is less noise and better clarity in the resulting image. Unless a consumer plans on producing very large images, 5 megapixels is generally sufficient and 3-4 may be enough if prints will be 5×7 or smaller.

The sensor which captures the light entering the camera lens is even more critical however. The sensor stores and displays data, converting the light into electrons. The sensor can be either CCD (charge-coupled device) or CMOS (complementary metal oxide semiconductor). CCD is the more mature technology and produces images with less noise. They also tend to be more expensive and consume more power but for those seeking the highest quality images, a CCD is the better choice at this time.

An important aspect of the CCD is the actual size of the sensor. Larger sensors provide higher resolution and less noise. Understanding how the size of the CCD sensor influences the quality of images and knowing what size sensor is adequate requires a bit more study. There are several articles available on line which could prove valuable for those wishing to learn more about this topic. Articles at http://www.photo.net/equipment/digital/sensorsize/ and http://www.photo.net/equipment/digital/basics/ are well written and knowledgeable.

A final consideration regarding the sensor in a digital camera is the availability of 1 CCD and 3 CCD models. As one might suspect more is often better. A camera with 1 CCD picks up image and color information through a single sensor. A model with 3 CCD has a sensor that picks up each of the different colors (Red, Green, and Blue) resulting in superior color reproduction.

Certainly the selection of a CCD sensor over a CMOS sensor, a larger sensor, or more sensors is not required in order to own a high quality digital camera capable of producing very good images. However, these features certainly do significantly enhance image quality and are the focus of attention for those seeking to produce the sharpest and most vivid images.
