Introduction To Raster Image

Introduction to Raster Images

There are basically 2 types of Images 1.Raster images & 2.Vector images. Vector images are based on mathematical objects such as lines and curves.

But what is a Raster image? It is a type of image made up of small rectangular pieces which are known as pixels. Pixel is a small part of an image i.e. an image is made by combining lots of pixels. That image is known as Raster Image. This Raster image is also known as bitmap images.

Raster ImageRaster images are dependent on the resolution that’s the reason that they have large size. The image becomes pixilated when the zoom level is increased. As Raster image is dependent on resolutions. Due to this some images can be rescaled, while other images are not seen clearly. In Raster image is measured in ppi (pixels per inch).

Raster Image 2

The color system used in Raster images is RGB (Red, Green, and Blue). The pixels usually smooth out visually for the user, who sees a photograph or drawing, when a Raster image is viewed.

The Formats of Raster Images

  • .tiff (tagged image file format)

It is tag based file format which promotes the interchange of digital photographs and line arts. Mostly Image Manipulation applications, page layout & publishing applications, faxing, scanning, word processing and other applications are supported by tiff. It is an image compression format. This format is developed by Aldus (Adobe Systems). The main purpose of this format is to create such an environment that the image data can Up till now 4 revisions are developed of .tiff

  • Revision 3.0 which is in HTML.

This memorandum is mainly developed by Aldus now known as Adobe in the year 1986.

  • Revision 4.0 which is in HTML.

This memorandum is developed on 31 April, 1987 by Tim Davenport of Aldus and Manny Vellon of Microsoft in conjunction. This revision was developed with minor enhancements.

  • Revision 5.0 which is also in HTML.

This Technical memorandum of Aldus and Microsoft was developed on 8/8/88. The basic new thing about this revision was the LZW compression, support for Palette Color images.

  • Revision 6.0 which is in PDF

This memorandum was developed by Adobe Developers Associations previously known as Aldus in March 1995.

  • .gif (graphic interchange format)

Gif is like short animation. In 1987 CompuServe developed this format. CompuServe developed this format to give some moving effect or animation to a still image.

  • . png (portable network graphics)

To improve the gif and to replace it .png was developed. It was developed by PNG Development Group in 1996

  • . jpeg (joint photographic experts group)

To compress the photographic images this file format is used. By this format we can adjust the storage size and image quality.

  • .bmp (bitmap image)

Bmp file format is very simple format and familiar to windows. Generally bitmap files are stored in Device Independent Bitmap (DIB) format, due to this format windows allow  display of bitmap image to any display device.

CorelDRAW Graphics Suite

Introduction

Hi readers ! This is Saumil back with some more on vector graphics. Previously we discussed about a very good vector graphics tool, The Adobe Illustrator. Now let us see another great tool for vector graphics, CorelDRAW.

Let’s know CorelDRAW

CorelDRAW is vector graphics editor developed to deliver optimum performance with vectors. CorelDRAW was developed by Corel Corporation which is situated in Ottawa, Canada. It is also the name of Corel’s Graphics Suite. CorelDRAW is designed to provide the user with  a capacity to edit & create vector graphics. As it is a vector based software, it is widely used as a key tool for print designing.

Journey from origin to X4

Corel Corporation was looking forward to develop a vector graphics editing software to accompany the bundle of other desktop publishing programs. So in 1987 Corel hired two software engineers namely, Michael Bouillon & Pat Beirne, & asked them to develop a vector graphics editor. As a result CorelDRAW was released in 1989. It was its first version. Then later in 1991 version 2 was released. Thereafter every year an updated version was released uptill version 6 came out in year 1995. Than version 7 was released in year 1997. The trend continued uptill the release of version 12 in year 2003. Than it had a break for about 2 years. This break was discontinued with the release of CorelDRAW’s version 13 popularly known as CorelDRAW X3. in yera 2006. Then in year 2008 CorelDRAW X4 was released, which is the  14th & the latest version of this software.

In this journey CorelDRAW was converted into a full graphics suite with addition of 3 more softwares. They were Corel PHOTO-PAINT which was a raster based graphics editor, Corel CAPTURE which was a image capturing assistant & Corel Power TRACE which is a tool to convert raster images to vector graphics. This is available inside the CorelDRAW.

Corel Corporation has contributed greatly to the graphics & designing industry by giving such a product, The CorelDRAW Graphics Suite.

Few Common Mistakes In Photoshop

Photoshop is an amazing software which gives any user the ability to create stunning digital art. Anyone can start on it but amongst the new users I see lots of mistakes which should not be happening. I believe this mistakes are as a result of them wanting to do everything in one art.

This article is not about tips and tricks but the focus of this articles in on what NOT TO DO in photoshop. Avoid this mistakes listed and you should do fine with your artwork.

Not Using Layers and Folder

Photoshop is based around the concept of working in Layers. I have seen many new users neglect working on new layers and then regretting their choice later. I adhere to the policy of doing each and every change on a new layer this way it is easier to edit, move, duplicate or delete, etc.

Grouping the layers in a folder based on your workflow also helps in navigating through large PSDs. Naming each layer and folder helps you identify easily when you need to go back to certain layer to re-edit it. This will help save lot of time and headaches.

Not Using Grids and Guides

Grids and Guides are for a reason, they are not for show. Its amazing how almost everyone claims to have “the eye” but trust me we often don’t have the correct alignment. Grids and guides will help a lot, so use them.

Not Learning Shortcuts

“Shortcut – A path between two points that is faster than the commonly used paths; A method to accomplish something that omits one or more steps”

Shortcuts save a lot of time, no matter which program you use learning the shortcuts is a must. Not only will this save time but your workflow will get faster. Photoshop also allows you to customize your shortcuts.

Abusing and Overusing Filters

I have seen many new artist use all the available filters in one art work. Even I was obsessed with them when I started out. Agreed they are fun and easy way to work and can at times give good results. Using them does not make you a great photoshop artist, instead it shows your amateurish level. Using discretion when using filters don’t overuse them.

Jarring Colours

Always know your colour theory, don’t use jarring colours. Art work should be such that the focus is on the art and not the colours used.

Working under 300dpi for Print

Most new users fall into the trap of working in 72 dpiTypically 300 dpi is best for print but always confirm with the printer.

When working with 72dpi users assume that they can always increase the pixel resolution and it will be fixed, but on printing the picture will appear pixelated.

Abusing and Overusing Blending Options

Similar to filters, beleved or embossed text and work will certainly mark you out as a amateur. Unless you have very strong reasons of using them stay away from them.

Using drop shadows should also be used with utmost care. Make sure you have the shadows in the right direction according to the lighting. Also they should be soft and subtle not harsh and overpowering.

Creating Logos in Photoshop

Though this an debatable point, I believe logos should be created in vector based programs like Adobe Illustrator. The main disadvantage of creating logos in photoshop is that when resizing them you will loose the quality and the image will appear pixelated.

Adobe Illustrator – An Industry Standard Vector Graphics Software

Introduction

Hello friends… I am back with something more regarding vector graphics. Up till now we have seen what are vector graphics & how they are used. Then we saw that where vector graphics are used & what are their different uses. Now we will see how vector graphics are created & edited. What are vector graphic file formats & other things related to vector. Lets enter into a new dimension of vector graphics.

The Software

There are many vector graphics editing & creating software in the market nowadays. For example Adobe Illustrator, Corel Draw, Macromedia Free-hand etc. Today we will discuss & know about a leading vector graphics software called Adobe Illustrator.

SS1

Adobe Illustrator  is a vector graphics software developed & marketed by Adobe Systems Inc. USA. This was a complimentary software of Adobe Photoshop series of raster graphic software. Illustrator was first developed for the Apple Macintosh Inc. in year 1986. Then the software became popular & it kept on developing resulting into its fourteenth edition out today.

In year 1988 Adobe Illustrator’s first version was commercially launched which was called Adobe Illustrator88. This was its basic version but still had a lot of features & tools. This version typically made to support Macintosh platform. Following this Adobe also developed Illustrator to support platforms like sun solaris, NeXT, Silicon Graphics IRIX etc but they were discontinued as a result of poor sales.

SS2

In early 1990 Adobe launched the second edition of Adobe illustrator in Macintosh platform named Illustrator  1.1 followed by another version called Illustrator 3.0.  Then Adobe took a leap & went ahead to launch a Windows platform based version of Illustrator & launched Illustrator 2.0 for Windows. Then next version for windows came which was version 4.0, but it got highly criticized because of similarities with Macintosh versions 7 Illustrator’s biggest market competitor The Corel Draw Graphics Suite. Adobe was pretty successful with Macintosh versions of Illustrator thus it launched version 5.0 for Macintosh in 1933.

After a big failure with the windows version Adobe worked upon the UI (User Interface) & functionality & came up with Illustrator 6.0 in 1996.  This version also failed in making something for the company. Still the 6.0 version was updated to a great extent. The biggest leap Adobe got in 1997 with launch of Illustrator version 7.0. This was a lot better 7 professional version of illustrator. Users were now being able to standardize themselves on Illustrator. From this period itself Adobe Illustrator was a standard software for vector illustrations.

Later adobe created history by acquiring Free-hand, an another vector tool, & initializing on Adobe Pagemaker. Although free-hand was sold to Macromedia after sometime. Adobe added some more extraordinary feature like web publishing, Raster previewing, PDF (Portable Document Format) & SVG (Scalable Vector Graphics) compatibility etc & launched Illustrator 9.0. This version also include some features like tracing.

SS3

Adobe now wanted something to boost up its sales & popularity of Illustrator & Adobe got it int the form of the Creative Suite (CS) series of Illustrator. Its 11th version The Adobe illustrator CS was launched in 2003 followed by CS2, CS3 & CS4. The creative suite series was technically advanced & well configured to match the needs of the illustrators. Today the latest version of Adobe Illustrator is CS4. This is its fourteenth version & still the software is growing.

For me as a vector artist & Adobe Illustrator user, this is the best software in terms of use, UI, tools, functionality & Quality up till now amongst the vector editing software i have used. I hope this article will help you know the software well & respect the art in you.

File Format(s)

Adobe Illustrator supports almost every file format associated with images. The official Illustrator file format is .AI. This is the standard file format invented by Adobe for Illustrators users. This file format saves the whole project as it as & it is supported by all versions of this software.

Character Designing – Beginners

Character Designing – Beginners

Designing a character is like playing the role of God.It is amazing ,creative, full of freedom ,power and control.Nothing can go wrong with your character , and even if it dose its always in your control.From Mickey Mouse’s famous three-fingered hands – drawn to save production time when the character was first developed for animations in the 1920s – to the elegant simplicity of Homer Simpson, character design has always been about keeping it simple. But aside from clean lines and easily readable features, what else are you going to need to know? There’s knowing what to exaggerate and what to play down, what to add to give a hint of background and depth, and what to do to develop personality.

Key Steps to Design your Character

Designing a character is similar to giving birth, since you are creating a whole new being, but it’s different because you get to pick all the character’s traits, personality and looks. You also have complete control over what the character does and does not do. You can design a character by using your imagination to work on this few steps.

Character

Envision the being. Is it a man, woman, or child? Perhaps it’s a giant, walking stick, an insect, a fish, a cat, a goat, a tiger, or a mixture of all types of animals. Maybe it’s a talking coin or another inanimate object come to life. Figure out what kind of being your being is going to be.

char-sketches22Personality

Pick its personality. Your walking stick can be laid back and happy, your insect can be ferocious. You can create a fearless fish, a catty cat, a glib goat, a terrified tiger or any personality that comes to mind. Your figure’s features are going to reflect its personality.

Features

Sketch a rough draft with the personality in mind. A laid back stick will be slouchy with half-closed eyes. A fierce insect is going to have a gargantuan stinger, big teeth and slanted, angry eyes. Your terrified tiger will have wide eyes, like a deer caught in the headlights, and a grimace showing his flat, useless teeth. Envision the personality traits of people you know that act in the manner of the character you’re creating. Reproduce those traits with your character’s stance and facial expression.

oku-sketches-06-apr-091Attributes

Give your character a few obvious attributes that are easy to reproduce. You want your character to be memorable with giant eyes, a weird hat, creepy teeth or other attributes that stand out from a crowd and make the character recognizable at a glance. You also want the attributes to be easy to draw, again and again, in case you make a comic strip or animation of the character and you find yourself drawing him nine million times.

Uniqueness

Be unique. If you are ending up with a droopy dog with sagging ears, a giant, yellow sponge that wears pants or a smart aleck rabbit that is constantly chomping on a carrot, you better rethink your character. You don’t want anything you create to be too similar to anything already out there, like Droopy Dog, Sponge Bob or Bugs Bunny.

fred9Naming Ceremony

Now, this is where you can have a lot of fun.You have your characters age,gender,personality,his uniqueness,probes and lot many things to assist you in this task.There can be endless number of names for a given character, but the best would be the one that justifies either all its qualities or the one that appeals the most and defines it, making him most memorable and unique

Happy Character Designing.

Vector Graphics Overview

Introduction

When working with graphics we often hear a word i.e. Vector. Sometimes we  just take vectors or vector graphics as something else than taking it as important it is. It might happen as we don’t know the meaning of the words vector graphics or because of some other reason.. So what are vector graphics & where are they used? Come on now to explore the world of Vector graphics with me…

Introduction to Vector

Vector is a type of image. The usual photographs we see on the internet or in our computer are Raster or Bitmap images. These are also image types. These image types work on pixels & represent the images in the form of pixels. These images are resolution dependent & their quality is affected depending on the viewing size.

Vector images are those which are in form of logos on any website. This image type works on basic geometrical forms like lines & curves & represent the images in the form of lines & curves. This allows this type of images to be resolution independent which means their quality doesn’t affect depending on the viewing size or their image size. Vector graphics are  2d & based on CMYK (Cyan Magenta Yellow Black) color type basically. This is because vector graphics are widely used in printing & print media industries. A printer is set to work with only CMYK color type, thus vector images are created using CMYK color type only. It can also be created using RGB (Red Green Blue) or HSB (Hue Saturation Brightness) color types.

Why Vector?

Vector graphics are very flexible in use as they are resolution independent. You can create an image large in size & can rescale it at a size you want. These images are not affected when rescaled. While raster images, when extended to a large size, lack its quality. We can see pixels in the image. Below image will make it much clear.

Ball_final

As you can see in the image above, the main image of a tennis ball is magnified up to 1200% or at 12x in the small square below. You can see the pixels or small squares making the image. This is the biggest disadvantage of raster images. While working with images which would need rescaling many times, vector images are preferable.

An Introduction to Typography

An Introduction to Typography

Introduction

Typography is an art of writing text in a specific format & style.  It includes arranging text, designing text, & formatting text in a way to gain an artistic gesture in writing or typing.  Arrangement of text includes tasks like line spacing, selecting font, point size, etc.  Typography is used in various fields in media & web.   Typography is an essential tool for vector graphic artists  &  people engaged in type setting, type design, calligraphy etc occupations. Below is a simple example of Typography.

Typography

History

The word typography is derived from Greek words i.e. typos which means to strike & graphos meaning to write.  Looking back in history, typography was optimized as a profession & people engaged in tis profession were known as typographers. It was seriously practiced & was a popular thing among people. It was modified according to needs as time traveled.

Types

Typography is not defined in any types but it is used in many different manners. Typography is used differently for printing, differently for display, & differently for web media. For printing typography is used in simple & bold manner so that it is easy to see & read. For display it is used in vivid forms like animated, kinetic, etc. Bright colors & bold symbols are easy to see & looks good when displayed. For web it is simple & artistic at a same time. this helps readers to have a pause & look at it while surfing or scrolling pages over the internet.

Dos & Don’t s

The basic thing to be taken care of while performing typography is that the words or text written should be clear in reading & understanding.  While stylizing the text it should be seen that design doesn’t make the text unreadable or it doesn’t hamper the essence of the text. When giving any color or font to the text, its appearance should be kept in mind & concentrated upon. Colors should be according to mood & type  of the illustration & color key should be thoroughly followed. Too bright colors are unpleasant to view  & too dull colors  sometimes lose the feel. Designs or styles given to the text should be neat & Alignment of each letter should be proper in order to preserve the aliveness of the text.

Below are some examples & pieces of reference related to typography..
