Hi Folks,

I m launching the blog www.en. digitalkamera.com. Here you will get Latest stuffs related to the world of digitalcamera and photography. Lets start with History of Digital Camera!!

We all Love digital camera and we love taking creative photographs also..But, did we ever thought about history of  digital camera . I mean, how it converted to the existing form. Most probably the answer is  ”No”. For those who didn’t know about it yet , this post can really help you.Lets start!!

CAMERA OBSCURA – This is believed to be the first camera in the world.In 1480,Leonardo da Vinci wrote the first detailed description of camera obscura in his Atlantic Codex, a 1,286 page collection of drawings and writings. The principle of camera obscura involves punching a hole in a dark box and putting a piece of light-sensitive material on the other side thereby providing a photograph. The first picture of a pinhole camera obscura is a drawing by Gemma Frisus’ De Radio, an astronomer (above photo on the left). He used the pinhole in his darkened room to study the solar eclipse of 1544.

As we went through ages,Science and Technology Developed.One of the first advanced digital cameras was SONY ProMavica MVC-5000. It has appeared in 1989. The word “MAVICA” stands for Magnetic Video Camera. The camera worked as follows: it recorded images as magnetic impulses on a compact 2-inch still-video floppy disk. The images were captured on the disk by using two CCD (charge-coupled device) chips. One chip stored luminance information and the other separately recorded the chrominance information. This camera provided a 720,000-pixel image.

The images could be stored on the floppy disk either in Frame or Field mode. When Frame was selected, each picture was recorded on two tracks and up to 25 images could be recorded on each disk. When Field was selected, each picture was recorded on only one track, allowing up to 50 images to be recorded. When recorded in the Field mode, images were less detailed as compared to images recorded in the two-track Frame mode. The MVC-5000 was considered to be the leader in image quality during its time.

” Another significant model of camera, XapShot was a Hi-band still video camera. The XapShot had a built-in flash, self-timer, and an unusual rechargeable lead acid battery. Also required was a kit which included one floppy disk, the battery, and computer interface card with software. The USA version of the XapShot could send a NTSC signal to a TV/VCR for playback and recording of images. There was also a very basic software utility that worked under System 6/7 for the Mac in conjuction with the Computer Eyes NuBus video capture card that the camera connected to. Later, a Plug-in shipped that worked with Letraset’s ColorStudio and then Adobe Photoshop to capture the images. ”

FIRST PRODUCTION CAMERA – I’m not talking about the latest production camera’s which costs millions..These are  Daguerrotype cameras of 1839 produced by Giroux in Paris.

They weighed 120 pounds each and cost 400 Francs (about $50). They were capable of producing Excellent shots.They consumed a lot of space and its mobility was ver poor.

FIRST COMPLETELY DIGITAL CONSUMER CAMERA :(Logitech FotoMan) – 1990. Dycam Model 1 B&W digicam was the world’s first completely digital consumer camera.

It stored 32 compressed images on  internal 1MB RAM. 1/3-inch, 376 x 240 pixel CCD at 256 gray levels. TIFF or PICT 2 format. 8mm fixed-focus  lens. Shutter 1/30 to 1/1000 second. Built-in flash. The  Dycam worked similarly to the Canon XapShot except  that it included the digitizing hardware in the camera  itself. The camera was attached to a PC to transfer images.

FIRST DIGITAL CAMERA WITH COPIER: Its name is DA VINCI (1993).It had no storage capability and photos are printed with help of a thermal copier.

FIRST MASS MARKET DIGITAL COLOR CAMERA : APPLE QUICK TAKE 100 – 1994.The first digital cameras for the consumer-level market that worked with a home computer via a serial cable were the Apple QuickTake 100 camera (February 17 , 1994), the Kodak DC40 camera (March 28, 1995), the Casio QV-11 (with LCD monitor, late 1995), and Sony’s Cyber-Shot Digital Still Camera (1996).

FIRST DIGITAL CAMERA WITH IMAGE AND SOUND  RECORDING : The RDC-1 was the first digital camera to offer both still and moving image and sound recording/reproduction. Its recording capacity on a 24MB PC card was 246 still pictures in standard mode, or 492 in economy mode, or 246 still images in economy mode each with 10 seconds of sound, or 173 still images in standard mode each with 10 seconds of sound, or four video scenes of 5 seconds each with sound, or one hour and forty-five minutes of sound only.

Now , the latest cameras offer much more than what we can image.Live recording,High definition videos, Sharing through Wifi and Bluetooth and  so on.

MODERN DIGITAL CAMERAS : Digital cameras, similar to conventional cameras, are available in point-and-shoot and digital single lens reflex (DSLR) models.

Point-and-shoot cameras: These cameras are small, inexpensive, and easy to use because they contain fixed lenses and a built-in flash. To frame a picture, they typically have a liquid crystal display (LCD)–based viewfinder. If they do have an optical viewfinder, they tend to inaccurately frame the image. The advantage and disadvantage of point-and-shoot models is that they are designed to be simple. Thus, they have limited user control over the camera. Some cameras have the focus and exposure set automatically.

DSLR cameras: In contrast to point-and-shoot cameras, DSLR cameras have optical viewfinders, removable lenses, external flashes, and the ability to focus and to adjust exposure manually when needed. It is a direct replacement of the conventional film–based single lens reflex (SLR) models used by physicians for decades. For these reasons, DSLR cameras tend to be more complicated and expensive than point-and-shoot models. The cost has decreased; a complete DSLR system can be purchased for less than $1000. The early generation DSLR units tended to be more expensive, larger, and bulkier than conventional film-based cameras. This is no longer the case, with today’s DSLR cameras becoming cheaper, lighter, and more compact with each successive generation.
