How are light trails captured? how to capture car light trails?


      Light trails are a colourful and creative effect that photographers can capture by employing long-exposure shooting on their camera. The basic principle of light trail creation is that by manually dropping a camera’s shutter speed to a very low level, light is captured by the sensor over an artificially long period of time, with every passing vehicle having its lights tracked and recorded over the visible distance of the road.

        To take a shot like this one, find a roadside vantage point in which no other moving objects are visible other than the passing vehicles. Second, mount the camera on a tripod, as stability is key while shooting long-exposure imagery. This is because if there is any camera shake while the unit’s shutter is open, then the captured light will lose its direction and smudge across the entire image. Next select the shutter priority setting on the DSLR camera and drop the shutter speed to the desired level , this means at least a 30 second exposure. Finally, automatically focus on the scene’s background and use an external remote to take the picture. Interestingly, the very same process is also used in light painting, a technique where the streaked light is controlled by the photographer manually, using light-emitting diodes (LEDs) to draw custom streaks across a dark backdrop and thereby essentially ‘painting’ in light.

How do barcodes work?

  How do barcodes work?           Barcodes are a machine-readable way of writing letters and numbers. A laser is shone onto the barcode and the reflected light can be interpreted by the barcode reader. There are many types of barcodes, but the ones most commonly found in supermarkets use a row of lines of different widths. The different widths represent different numbers.           In the some Country many items are coded with a GTIN – Global Trade Item Number. This allows the manufacturer to print the barcode on the packages. The numbers are unique to that item. The barcode only has a number, but no product information. That is held in a database which the retailer can access at the point of sale. It also means that shops can set their own prices and change them easily.


 [1] HTTP:                            (Hyper Text Transfer Protocol) The communications protocol used to connect to servers on the Web. Its primary function is to establish a connection with a Web server and transmit HTML pages to the client browser or any other files required by an HTTP application. Addresses of Web sites begin with an http:// prefix; however, Web browsers typically default to the HTTP protocol. For example, typing is the same as typing                HTTP is a "stateless" request/response system. The connection is maintained between client and server only for the immediate request, and the connection is closed. After the HTTP client establishes a TCP connection with the server and sends it a request command, the server sends back its response and closes the connection.                Version 1.0 of HTTP caused considerable overhead to a Web download.

2. WEB SEVER (Apache Server & IIS Server)

                 A computer that delivers Web pages to browsers and other files to applications via the HTTP protocol. It includes the hardware, operating system, Web server software, TCP/IP protocols and site content (Web pages and other files).                Web server may refer to just the software and not the entire computer system. In such cases, it refers to the HTTP server (IIS, Apache, etc.) that manages requests from the browser and delivers HTML documents and files in response. It also executes serverside scripts (CGI scripts, J SPs, ASPs, PHP, ASP.NET etc.) that provide functions such as database searching and e-commerce There Two most widely Used Web Server    [1] Apache Server     [2] IIS Server  [1] Apache Sever                     Apache HTTP Server is an open source HTTP web server for Unix-like systems (BSD, Linux, and UNIX systems), Microsoft Windows, and other platforms.
