Information On How Your Digital Camera Works

Basically, a digital camera records electronic images by focusing light through a series of lenses onto a sensor. The images are stored as binary digital data on fixed or removable devices, which can later be read by a computer. This is an extremely simplified explanation; the process is a bit more complicated, but a lot more interesting!

Most digital cameras have an image sensor called a charge coupled device (CCD). A few digital cameras have a complimentary sensor metal oxide semiconductor (CMOS) instead. Both of these devices convert light into electrical charges and both facilitate storage.

The sensors are also used to filter light into the three basic primary colors and then recombine them to get a full spectrum. The more expensive the digital camera, the more sophisticated the process and the better the color quality. Three sensors will each filter a different color.

The shutter speed and aperture control the amount of light that reaches the sensor. The shutter speed is set automatically on most digital cameras, while the aperture can be either automatic or manually controllable. Most of us are grateful for the automatic settings, but photographers and serious hobbyists appreciate the aperture flexibility.

There are different types of lenses that digital cameras use: fixed-focus, fixed-zoom, digital-zoom, optical zoom lenses and replaceable lens systems. You will usually find fixed-focus and fixed- zoom lenses in inexpensive digital cameras. Optical-zoom lenses, with both wide and telephoto lenses, are usually found in more sophisticated, expensive cameras. A digital zoom is a process whereby pixels are actually "chosen" from the central part of the frame and enlarged. This feature can cut out unnecessary background, but it can also result in a less-focused, fuzzier image.

You can see your pictures on an LCD viewing screen on the back of your digital camera. This is only suitable for a quick check of picture quality (was everyone smiling?), not for really appreciating the photo. The number of megapixels (MP) in your digital camera determines the resolution -- the higher the number, the better the photo clarity!

Knowing your megapixels gives you an excellent idea of the quality of printed pictures at a given size. A 1MP digital camera will give you pictures that are perfectly suitable for web viewing or emailing. These pictures are easy to download and are of decent clarity and resolution online. The photos taken with a 2MP digital camera will generate quality, high resolution, 4x5 inch prints. Larger prints require an even larger MP number.

A great digital camera advancement is the way data is stored. Early digital cameras held all images on internal memory devices. These digital cameras were not capable of much storage and transferring to a computer was a cumbersome process. Today's digital cameras use reusable and removable storage. Memory sticks, CompactFlash and SmartMedia cards add lots of extra storage space and make downloading a snap. Other devices such as writeable CDs and DVDs, hard disks, floppy disks and microdrives have given consumers lots of options for storing images, with lots of room available!

Digital Camera Software

A combination of a digital camera, a color scanner and image manipulation software is highly recommended. The software digital camera software that is included also provides professional level workflow solutions for seamless use.

Most of the software is designed for digital camera users, compatible with most current digital camera models.

photo editing software & photo printing software that's renown for its ease of use. At last there's easy-to-use digital camera software for both home and business users.

Image

The image sensor employed by most digital cameras is a charge coupled device (CCD). Some current digital camera models store combinations of video (MPEG or AVI movies), image sequences or sound. Although Canon's images are slightly better, the Casio is an ultra-thin, sleek digital camera that doesn't sacrifice overall image quality.

Easy-to-understand information about digital cameras, accessories, image editing and more. Image quality depends on the resolution of the digital camera. To make image files smaller almost every digital camera uses some form of compression. This EasyShare digital camera's resolution of 5 megapixels, 3x optical zoom and an all-glass lens combine for amazing image detail and clarity.

With an image stabilizer, this digital camera produces clear, even images even in shaky conditions. Resolution is the most talked about digital camera characteristic and is often used to describe image quality.

If you have the option, choose optical rather than digital image stabilization in your camera. It is probably the best digital camera made and produces image quality that rivals medium format film (e.g., 6x6cm Hasselblad).

Image processing for single-sensor digital camera: a mathematical challenge This entry is from Wikipedia, the leading user-contributed encyclopedia. A typical slave unit will fire on the pre-flash it senses while the digital camera captures the image on the last flash. The image quality available from digital cameras is astonishingly good.

Film

In fact, a digital camera is better quality than a film camera in many important respects! The digital cameras enjoy the advantage of a built-in digital signal processor that your roll of film doesn't have.

Add an external or speed light flash to your digital camera or film camera. Many digital cameras are comparable to a 35 mm camera in price without the extra added cost of buying or developing film. Back to top Printing pictures Unlike with film cameras, you can print digital photos at home.

Is considering laying off the development of new film cameras as it focuses resources on its digital camera business. Though digital cameras don't use film, they have adopted the same rating system for describing the sensitivity of the camera's imaging sensor. So far, very few digital cameras have been produced with a receptor using the full size of 35mm film.

Whether you're using film or a digital camera, bring a sturdy tripod. Shooting with a digital camera is somewhat like shooting slide film. A couple years ago, I got into the digital camera thing to the point that I pretty much parked my roll film cameras. The digital camera scenario is similar in that mega pixels are similar to film size. To design and build a high performance digital cine camera with the quality of 35mm film and convenience of a camcorder.

Quality

The quality of your pictures can be enhanced by the digital camera accessory you choose. You'll find quality brands of digital cameras, 35mm cameras, lenses, video cameras, memory cards and camera accessories at great prices. An easy to use quality digital camera purchase will be fully used by staff and students. However, not all digital cameras can produce prints of the same quality. I wanted a go-anywhere high quality digital camera that's user-friendly with both auto & manual controls. At the cheaper end of the digital camera scale, the quality can be remarkable for the price.

Buy

It is better to buy a digital camera with a 100% glass lens for the best pictures. Many retailers advertise their best buy digital camera as one with a plastic lens. You should also look for the best buy digital camera packages with the most RAM that you can afford. A lot of unscrupulous retailers will advertise a price for a best buy digital camera but then charge high shipping costs.

Finally, ensure that you have accounted for any shipping costs before you make your final decision over which best buy digital camera you purchase. There's never been a better time to buy a digital camera. Having to buy re-chargeable batteries and a charger will typically add from $20 to $100 to the cost of your digital camera.

As a person constantly taking photos I made this page as a lot of people keep asking me what digital camera they should buy. Find discount computers, cheap digital camera, buy digital cameras. Try before you buy - I've always been a firm believer that you should handle a digital camera before you buy it.

Size

Experienced digital camera users know pixel size isn't everything. The small size and versatility allow easy integration of digital cameras into all parts of the curriculum. If you care more about price and features than compact size, choose a standard size digital camera.

There are three basic "sizes" of digital cameras, and knowing what size camera suits your needs will make your search much simpler. For digital SLR cameras with interchangeable lenses it's more difficult as different cameras have different size sensors. This is why I am currently looking for an extra digital camera featuring a minimal size combined with a maximum amount of useful features.

These are about the size of a matchbook and used in digital cameras made by Nikon, Canon, Kodak and many others. When choosing a digital camera you have to think about the resolution of the pictures, size and memory. A larger inner diameter makes the L-Ring 3200 perfect no matter the lens size of your digital camera. This has nothing to do with your camera being digital it is entirely a result of smaller frame size.

Video

Webcams are digital cameras attached to computers, used for video conferencing or other purposes. However, modern digital photography cameras have a video function, and a growing number of camcorders have a still photography function. Modern compact digital cameras are typically multifunctional, with some devices capable of taking photographs, video, and/or sound.

Classification Digital cameras can be classified into several groups: Video cameras Professional video cameras such as those used in television and movie production. Some digital cameras have direct video out..... Another alternative, although not directly a digital one, would be to purchase one of the analog peephole video cameras.

Lens

The super multi layer lens coating reduces flare and ghost, a common problem with digital cameras. The vast majority of digital cameras are "point-and-shoot" models with a single, non-interchangeable lens. Because auto focusing in most digital cameras is done through the lens, the focus shift is automatically taken care of. Focus and Exposure: Fixed-focus digital cameras have a lens that is preset to focus at a certain range. These depend on the actual (as opposed to relative) diameter of the lens aperture, which makes them especially painful for digital cameras.

Memory

You can find a memory card reader or extra battery to keep your digital camera powered up for any circumstance. Some professional digital cameras and memory card readers connect to the computer over FireWire. SD is now the most popular type of digital camera memory. Many types of memory cards are available for use with your digital camera. Files deleted from PC, digital camera or memory stick can be restored with high speed and reliability. When using your digital camera to make movies it is also very important to have ample Flash Memory on hand too.

Battery

All digital cameras can run on rechargeable batteries of one of two types: an expensive battery pack or a set of AA batteries. A battery is taped to the inside cover of the box that the Olympus digital camera came in. Take a few moments to look around, keep your camcorder, digital camera or laptop computer working like new with a fresh battery today! The Digital Camera Battery can power two devices at the same time and has adjustable outputs that match each device automatically.
