Designing Softwares

I started designing at the age of 20 after my graduation. Initially it was neither my passion nor my interest. But today I cannot think of anything beyond it. I cannot imagine myself doing any other job. My choice of weapons for designing are Adobe Photoshop, Adobe Illustrator, Corel Draw, Adobe Muse, Adobe Flash, Adobe Dreamweaver and Adobe Edge Animate.

To design any kind of web related graphics I use Adobe Photoshop and for any graphics related to print media I use Adobe Illustrator and Corel Draw. For application/website designing I use Adobe Muse, Adobe Dreamweaver, Adobe Edge Animate and Adobe Flash. We will first learn the applications of Adobe Photoshop.

What is CMYK and what is RGB?

CMYK: CMYK color model refers to the four inks : cyan, magenta, yellow, and key (black). When a color photo is printed it is literally separated into these four colors and printed one color at a time. These four colors then combine to give you the full color image. 
This color model is a subtractive color model. CMYK is a standard color model used in offset printing for full-color documents. Because such printing uses inks of these four basic colors, it is often called four-color printing.

RGB: The RGB color model stands for Red, Green and Blue. Files in RGB format are intended for use on electronic systems like TVs, mobile phone displays and computer monitors. RGB color system, constructs all the colors from the combination of the Red,Green and Blue colors. The RGB color model is an additive color model in which red, green, and blue light are added together in various ways to reproduce a broad array of colors. RGB is a device-dependent color model: different devices detect or reproduce a given RGB value differently, since the color elements and their response to the individual R, G, and B levels vary from manufacturer to manufacturer, or even in the same device over time. Thus an RGB value does not define the same color across devices without some kind of color management.

Image Types

Image Types

Raster Images |  Vector Images | Compound Format 

Raster Images : These types of images are composed of pixels and are dependant on resolution for clarity. Raster images use many colored pixels or individual building blocks to form a complete image. JPEGs, GIFs and PNGs are common raster image types. Raster imaged cannot be resized without compromising with the quality of the picture because they are made of fixed number of colored pixels.

Vector Images : These types are images are not dependant on resolution and can be enlarged without distortion. Vector images are constructed using mathematical formulas rather than individual colored blocks, vector file types such as EPS, AI and cdr are excellent for creating graphics that frequently require resizing. 

Compound Format : These are formats containing both pixel and vector data, possible other data, e.g. the interactive features of PDF.
