VECTOR DRAWING PROGRAMSWritten by BLUR LOTERIŅA
One of best tools in creating and modifying a vector-based image is Adobe Illustrator. Artworks done through Illustrator can be used for print, multimedia and online graphics.Illustrator is used to open and manipulate vector-based drawing. Vector-based images are series of points connected by lines. It is also called object-oriented or draw images. It uses geometrical formulas to represent images. Vector files have graphical elements called objects. These objects have properties including color, shape, outline, size, and position on screen as well as definition of object. It is also a self-contained entity, which means that properties of object can be moved and changed without affecting other objects while clarity and crispness are preserved. This characteristic makes a vector-based image suitable for illustration and 3D modeling. An image is created by connecting vector point with straight or curved lines. Vector point or anchor point is basis and most fundamental component in every vector image Unlike bitmap images, vector-based images are resolution dependent. The quality of image increases as resolution increases. So it looks better on devices with higher resolution. It can also be resized and stretched and does not become grainy. Since bitmap images are composed of dots, it losses its quality and proportion when stretched.
| | HOW DO YOU USE THE GRADIENT TOOL IN PHOTOSHOPWritten by BLUR LOTERIŅA
There are different ways in eliminating opacity on images. One of basic techniques is use of gradient tool. A gradient tool is used to edit or modify a part or entire layer of an image. It is located in tool bar and there is a window provided to customize your gradient.Different gradient shapes include diamond, reflected, linear, etc. There is also gradient blending modes for foreground and background colors. Just double click tool bar in color picker to change color of foreground or background. You can have your foreground transparent. its color fades so you will be able to see layers below. Fading is done by swiping across pixels. Different locations for gradient include Adjustment Layer, Fill Layer, Layer Styles Menus and Tool Options Bar. There are two gradient types or settings, solid and noise. Solid is a gradient generated algorithmically, while noise is from RGB values. Solid gradient is used for manually set colors, while noise is for numerous color bands. Before you can use gradient tool, convert first background layer to a regular layer. Then, create a gradient layer. Choose any gradient style and make sure that gradient layer is transparent. The transition between color bands can be determined by adjusting smoothness. Short strokes result to sharper gradient and long strokes result to smoother gradient.
