DIGITAL PHOTOGRAPHY


INTRODUCTION



Aperture
  • Referred  to the lens diaphragm opening inside a photographic lenses.
  • The size of the diaphragm opening in a camera lens regulates amount of light passes through onto the film inside the camera.
  • Calibrated in f-number or f-stops. f/64, f/32, f/22, f/16, f/8.0, f/5.6, f/2.8, f/1.8
  • Large aperture will decrease depth of field while small aperture will give you larger depth of field


Shutter Speed
  • Also known as “exposure time”, stands for the length of time a camera shutter is open to expose light into the camera sensor
  • If the shutter speed is fast, it can help to freeze action completely.
  • The aperture diaphragm of a lens (bigger or smaller values) and timing (open and close) of the camera's shutter curtain (BOTH).
  • 1/8000, 1/4000, 1/1000, 1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8, 1/4, 1/2, 1 or -1, -2 etc. are essentially indicators of the duration (timing) at which the shutter curtain opens up and closes during an exposure process.
  • A 1/125 setting means the shutter curtain open and close within one hundred and twenty five of a second while 1 means an one full-second the shutter opens up during exposure to absorb the available light source onto the film to form an exposure.


ISO
  • ISO is level of sensitivity of image sensor.
  • The lower the number the less sensitive your camera is to light and the finer the grain/noise.
  • Measured in numbers ISO 100, ISO 200, ISO 400, ISO 800, ISO 1600, ISO 3200.
  • ISO 100 and ISO 200 is a base ISO.
  • You should increase the ISO when there is not enough light, when there is plenty of light you should always use the number of base ISO.

Publishing and Web Design






INTRODUCTION



Publishing is the process of production and dissemination of literature, music,or information — the activity of making information available to the general public. In some cases, authors may be their own publishers, meaning originators and developers of content also provide media to deliver and display the content for the same. Also, the word publisher can refer to the individual who leads a publishing company or an imprint or to a person who owns/heads a magazine.


Traditionally, the term refers to the distribution of printed works such as books (the "book trade") and newspapers. With the advent of digital information systems and the Internet, the scope of publishing has expanded to include electronic resources such as the electronic versions of books and periodicals, as well as micro publishing, websites, blogs, video game publishers, and the like.


Publishing includes the following stages of development: acquisition, copy editing,production, printing (and its electronic equivalents), and marketing and distribution. Publication is also important as a legal concept: As the process of giving formal notice to the world of a significant. Intention, for example, to marry or enter bankruptcy; As the essential precondition of being able to claim defamation; that is, the alleged libel must have been published, and For copyright purposes, where there is a difference in the protection of published and unpublished works. Web design encompasses many different skills and disciplines in the production and maintenance of websites. The different areas of web design include web graphic design; interface design; authoring, including standardised code and proprietary software; user experience design; and search engine optimization. Often many individuals will work in teams covering different aspects of the design process, although some designers will cover them all.


The term web design is normally used to describe the design process relating to the front-end (client side) design of a website including writing mark up. Web design partially overlaps web engineering in the broader scope of web development. Web designers are expected to have an awareness of usability and if their role involves creating mark up then they are also expected to be up to date with web accessibility guidelines.
