Few Facts Of Digital Cameras
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.
