Using the selection tool in Photoshop (Very basic) Cont.

Selection and Learning in Photoshop.

In Adobe Photoshop one of the most important concepts  is Selection.
See in your tool area. There is a tool named Rectangular Selection Tool.
Use this tool on your image to select an area of the image. This lets Photoshop know that that's the area you want to work on.

Selection and making a square.
To add to a selection, hold Shift before dragging.
Tomake the selection exactly square, start dragging, then hold Shift.
You can press Ctrl+D to "deselect" and remove the selection at any time.

Elliptical Selections and subtracting Selections

Hold down on the Selection Tool on the Toolbar, and choose the Ellipse.
To move the selection, just click inside it and drag.
Holding Alt while selecting subtracts that area from the selection. I've done that with the Ellipse Selection Tool

Using the Layers window in Photoshop

The Layers window shows the various layers that your image is made up of.
To make a new layer, click the New Layer button, as shown by the red arrow.
To work on a different layer, click on that layer. The eyeball will apear next to that layer.
You can drag layers up and down the list.
Note – create a new layer for each part of your image. More you need. This allows you to go back and edit the layers individually and you can modify easily. Every Adobe Photoshop beginner at some time makes a masterpiece, only to find out that they did it all on one layer, and now they can't remove those pink clouds they put on it.

2D & 3D computer graphics

Today, computers and computer-generated images touch many aspects of our daily life. Computer imagery is found on television, in newspapers, for example in their weather reports, or for example in all kinds of medical investigation and surgical procedures. A well-constructed graph can present complex statistics in a form that is easier to understand and interpret. In the media "such graphs are used to illustrate papers, reports, theses", and other presentation material.
Many powerful tools have been developed to visualize data. Computer generated imagery can be categorized into several different types: 2D, 3D, and animated graphics. As technology has improved, 3D computer graphics have become more common, but 2D computer graphics are still widely used. Computer graphics has emerged as a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Over the past decade, other specialized fields have been developed like information visualization, and scientific visualization more concerned with "the visualization of three dimensional phenomena (architectural, meteorological, medical, biological, etc.), where the emphasis is on realistic renderings of volumes, surfaces, illumination sources, and so forth, perhaps with a dynamic (time) component".

2D computer graphics

2D computer graphics are the computer-based generation of digital images—mostly from two-dimensional models, such as 2D geometric models, text, and digital images, and by techniques specific to them. The word may stand for the branch of computer science that comprises such techniques, or for the models themselves.

2D computer graphics are mainly used in applications that were originally developed upon traditional printing and drawing technologies, such as typography, cartography, technical drawing, advertising, etc.. In those applications, the two-dimensional image is not just a representation of a real-world object, but an independent artifact with added semantic value; two-dimensional models are therefore preferred, because they give more direct control of the image than 3D computer graphics, whose approach is more akin to photography than to typography.

Pixel art
Pixel art is a form of digital art, created through the use of raster graphics software, where images are edited on the pixel level. Graphics in most old (or relatively limited) computer and video games, graphing calculator games, and many mobile phone games are mostly pixel art.

Vector graphics

Example showing effect of vector graphics versus raster (bitmap) graphics.

Vector graphics formats are complementary to raster graphics, which is the representation of images as an array of pixels, as it is typically used for the representation of photographic images.[4] There are instances when working with vector tools and formats is best practice, and instances when working with raster tools and formats is best practice. There are times when both formats come together. An understanding of the advantages and limitations of each technology and the relationship between them is most likely to result in efficient and effective use of tools.

3D computer graphics
3D computer graphics in contrast to 2D computer graphics are graphics that use a three-dimensional representation of geometric data that is stored in the computer for the purposes of performing calculations and rendering 2D images. Such images may be for later display or for real-time viewing.
Despite these differences, 3D computer graphics rely on many of the same algorithms as 2D computer vector graphics in the wire frame model and 2D computer raster graphics in the final rendered display. In computer graphics software, the distinction between 2D and 3D is occasionally blurred; 2D applications may use 3D techniques to achieve effects such as lighting, and primarily 3D may use 2D rendering techniques.



3D computer graphics are often referred to as 3D models. Apart from the rendered graphic, the model is contained within the graphical data file. However, there are differences. A 3D model is the mathematical representation of any three-dimensional object. A model is not technically a graphic until it is visually displayed. Due to 3D printing, 3D models are not confined to virtual space. A model can be displayed visually as a two-dimensional image through a process called 3D rendering, or used in non-graphical computer simulations and calculations.

Inline image, using IMG, OBJECT or APPLET.

There are three ways to include inline objects in HTML.
The IMG element is the most common method for using graphics in HTML pages. For faster display, the width and height of the image can be given as attributes. One attribute that is required is alt, used to give an alternate textual string for people browsing with images off, or who cannot see the images. The string cannot contain any markup. A longdesc attribute lets you point to a longer description - often in HTML - which can have markup and richer formatting.
The OBJECT element in HTML can contain other elements nested within it, unlike IMG which is empty. This means that several different formats can be offered, using nested OBJECT elements, with a final textual alternative (including markup, links, etc) right at the center. The outermost element which can be displayed will be used.
The APPLET element is used for embedding applets into the HTML page. These applets can do many things biut o\a common task is to use them to display images, particularly ones in unusual formats or which need to be presented under the control of a program for some other reason.

Inclusion in XML,SVGA,CSS

Inclusion in XML

The XML specification does not prescribe or limit which graphics format you can use. It also does not provide a standard method to describe image inclusion. Work in progress at W3C on XLink and XPointer will add standard hyperlinking capabilities - including links to graphics - to XML. This work provides the same hyperlinking capabilities HTML users will be familiar with - simple, since ended links to embedded media and simple, single-ended hypermedia links - but also provides more advanced compound links, bidirectional links, and out of line links. This provides a standardised basis which XML languages can use for the actual linking part.

Scalable Vector Graphics (SVG)

SVG, a vector graphics format designed at W3C, written in XML and stylable with CSS, is starting to become a popular choice for including graphics in XML documents. It may be included either by linkage, or by textual inclusion in an XML document that uses a different namespace. Because SVG can itself include raster images such as JPEG and PNG, SVG can be used to add raster and mixed vector/raster graphics to XML documents. SVG uses XLink and XPointer to provide linking functionality.
SVG does not limit but does prescribe the formats that can be used. All conformant SVG implementations must support PNG and JPEG and SVG images. Other formats may also be supported by various implementations, but these two can be relied upon.

Background image, using CSS

Any XML element can (when displayed visually) be given a background image using Cascading Style Sheets (CSS). The background color can also be specified, and the image will composite onto the background color if it has transparent portions. This allows the same image to be re-used with different visuall presentations. The width and height of the image can be adjusted. It can repeat in the horizontal(x) direction, vertical (y) direction, both , or neither. The position of the image relative to the box taken up by the element can be adjusted.
CSS does not prescribe or limit which graphics format you can use.

Graphics on the Web



There is no limit in the Web specifications to the graphical formats that can be used on the Web. You just need a MIME type so that the format is labelled correctly for transfer across the Web, and so that a suitable viewer (if one exists) can be located at the other end.
In practice, certain formats are more widely understood than others; certain formats are more suited to one type of graphical data than another; so you should make an informed choice about what format to use.

Animation is nothing but using of graphics.

Computer animation (or CGI animation) is the art of creating moving images with the use of computers. It is a subfield of computer graphics and animation. Increasingly it is created by means of 3D computer graphics, though 2D computer graphics are still widely used for stylistic, low bandwidth, and faster real-time rendering needs. Sometimes the target of the animation is the computer itself, but sometimes the target is another medium, such as film. It is also referred to as CGI (computer-generated imagery or computer-generated imaging), especially when used in films.
To create the illusion of movement, an image is displayed on the computer screen and repeatedly replaced by a new image that is similar to the previous image, but advanced slightly in the time domain (usually at a rate of 24 or 30 frames/second). This technique is identical to how the illusion of movement is achieved with television and motion pictures.

How to start with/Very basic of Graphics design.


Welcome to my 1st beginning dig. Simply be courage you can draw! I think you can hold or can move a mouse. If not no problem. You must can. Believe me. Ok, Let start.
This operation for those who use Windows Operating System (like 2000, XP, Vista etc).

Click in your desktop start button. Ok , there is a list- go to the “All Programs” and select “Accessories” then there is a pop-up menu select “Paint”. Very fine!

Now you can see there is a working area and some tools in left side.


Hold your left side mouse in working are and look! There are a line which is following your mouse. Un press your mouse, now you can click to “Eraser” tools beside your left corner. Come on the working are where were you draw something. Now press and hold the mouse and follow the line you draw. See, it is very easy.
Try again, try again and try again with other tools.

Thank you.

Motion graphic design.

Motion Design is a subset of graphic design in that it uses graphic design principles in a film or video context (or other temporally evolving visual medium) through the use of animation or filmic techniques. Examples include the typography and graphics you see as the titles for a film, or opening sequences for television or the spinning, web-based animations, three-dimensional logo for a television channel. About 12 minutes in every hour of broadcast television is the work of the motion graphics designer, yet it is known as the invisible art, as many viewers are unaware of this component of programming.[citation needed] Although this art form has been around for decades, it has taken quantum leaps forward in recent years, in terms of technical sophistication. If you watch much TV or see many films, you will have noticed that the graphics, the typography, and the visual effects within this medium have become much more elaborate and sophisticated.
Contents

• 1 Technology
• 2 Notable Motion Designers
• 3 Motion Design & digital compositing software packages

Graphics Technology

The elevation of this art form is largely due to technology improvements. Computer programs for the film and video industry have become vastly more powerful and more available. Probably the leading program used by motion graphic designers is Adobe After Effects, which allows them to create and modify graphics over time. Adobe After Effects is sometimes referred to as "Photoshop for film." A relatively recent product in the market is Apple Inc. Motion, now a part of Final Cut Studio. Adobe Flash is widely used to create motion design for the web.
A typical motion designer is a person trained in traditional graphic design who has learned to integrate the elements of time, sound and space into his/her existing skill-set of design knowledge. Motion designers can also come from filmmaking or animation backgrounds.

The study of computer graphics.

The study of computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.

As an academic discipline, computer graphics studies the manipulation of visual and geometric information using computational techniques. It focuses on the mathematical and computational foundations of image generation and processing rather than purely aesthetic issues. Computer graphics is often differentiated from the field of visualization, although the two fields have many similarities.

Applications
* Computational biology
* Computational physics
* Computer-aided design
* Computer simulation
* Digital art
* Education
* Graphic design
* Infographics
* Information visualization
* Rational drug design
* Scientific visualization
* Video Games
* Virtual reality
* Web design

Computer graphics.

The term computer graphics has been used in a broad sense to describe "almost everything on computers that is not text or sound "Typically, the term computer graphics refers to several different things:
• the representation and manipulation of image data by a computer
• the various technologies used to create and manipulate images
• the images so produced, and
