Photo Editing techniques
July 20, 2018camera, masscommunication, media, notes, photoediting, photography, photojournalism, techniquesNo comments
Photo editing is the changing of images. Some types of editing, such as airbrushing, are done by hand and others are done using photo editing programmes like Adobe Photoshop. Photo editing is done for many reasons. Photo editing is sometimes called photo manipulation, usually when it is used to trick people.
Reasons to edit a photo include:
• Fixing errors (red-eye, contrast, brightness, etc.), practical jokes, and tricking people.
• To remove unwanted elements from a photo we may crop it.
• Photo editing is also used to make completely new images.
Here are few of the best photo-editing software available today. Among this Adobe Photoshop is the best. Adobe Photoshop, Adobe Lightroom, Corel Paint Shop Pro, Serif Photo Plus, Apple Aperture, GIMP, Paint.net, Phase One Capture, and One Pro Pixelmator.

Common Image Formats in Digital Cameras
July 20, 2018camera, digitalimage, masscommunication, media, notes, photography, photojournalism, typesNo comments
One of the most direct ways to capture an image is a digital camera which uses a special semiconductor chip called a CCD (charge coupled device) to convert light to electrical signals right at the image plane. The quality of the images created in this manner is closely related to the number of pixels the CCD can capture.
The most common image file formats, the most important for cameras, printing, scanning, and internet use, are JPG, TIF, PNG, GIF, and BMP.
Digital cameras and web pages normally use JPG (Joint Photographic Experts Group)files - because JPG heroically compresses the data to be very much smaller in the file. However, JPG uses lossy compression to accomplish this feat, which is a strong downside. A smaller file, yes, there is nothing like JPG for small, but this is at the cost of image quality.
TIF (Tagged Image File Format) is lossless, which is considered the highest quality format for commercial work.
GIF (Graphics Interchange Format) was designed by CompuServe in the early days of computer 8-bit video, before JPG, for video display at dial-up modem speeds.
PNG (Portable Network Graphics) can replace GIF today (web browsers show both), and PNG also offers many options of TIF too.
Camera RAW files are very important of course, but RAW files must be processed into regular formats (JPG, TIF, etc) to be viewable and usable in any way.
BMP file format (Windows bitmap) handles graphics files within the Microsoft Windows OS. Typically, BMP files are uncompressed, and therefore large and lossless; their advantage is their simple structure and wide acceptance in Windows programmes.
What is a Digital Image?

A digital photo is made up of a series of pixels (picture elements). Most of today’s digital photos use a “24-bit RGB” system to color each pixel.
When using digital equipment to capture, store, modify and view photographic images, they must first be converted to a set of numbers in a process called digitization or scanning. Computers are very good at storing and manipulating numbers, so once your image has been digitized you can use your computer to archive, examine, alter, display, transmit, or print your photographs in an incredible variety of ways.
Pixels
Digital images are composed of pixels (short for picture elements). Each pixel represents the color (or grey level for black and white photos) at a single point in the image, so a pixel is like a tiny dot of a particular color. By measuring the color of an image at a large number of points, we can create a digital approximation of the image from which a copy of the original can be reconstructed. Pixels are a little like grain particles in a conventional photographic image, but arranged in a regular pattern of rows and columns and store information somewhat differently.
Types of Digital Images
For photographic purposes, there are two important types of digital images— color and black and white. Colour images are made up of colored pixels while black and white images are made of pixels in different shades of grey.
Resolution
The density of pixels in an image is referred to as its resolution. The higher the resolution, the more information the image contains. If we keep the image size the same and increase the resolution, the image gets sharper and more detailed. Alternatively, with a higher resolution image, we can produce a larger image with the same amount of detail.

Difference between Advertisement and Public Relations
July 17, 2018advertising, difference, journalism, masscommunication, media, news, notes, publicrelationsNo comments
One of the most important and most often used tools that
business concerns employ is advertising. It is used to convey messages to
targeted audiences. Advertising can be extremely costly to employ. The process
of conveying messages to an audience which may be composed of present or
prospective customers through a single medium or multiple mediums is called a
campaign.
On the other side the main role of public relations is to increase
interest and awareness of the audience that you have targeted. This process or
campaign as it is also called does not necessarily try to convince or persuade
them to purchase the product. The public relations plan seeks to increase
awareness and create a positive image of the company through messages that
educate and provide information.
A combination of the two methods is generally regarded as
most effective. A marketing strategy that is an incorporation of the two
methods to produce the desired results would be the ideal process. Although
advertising requires a bigger budget public relations is often considered to be
the larger scale operation because advertising deals only with marketing and
sales while public relations encompasses the total communications activity of
the entire organisation.
