The basic things behind this topic are that the designers always attempt to cut down on this raster period as required as possible. So, they take efforts to dally that time when the designer launch Photoshop and minimize Illustrator. However, the author has less knowledge about Photoshop. On the other hand, you can look much about a vector-based figure is completed by the author out of a total of primitives, lines and shapes for better and effective look. However, it is much difficult to imagine about the opportunity to find any of those element and modify any of its properties. In this way, editors are creating other way to modify the icons designs that suitable for every application. So, the Adobe Photoshop adepts is create sharpening their feather to abscond a viperous remark here and impressive in relation to the required for the author to known about the tutorial and learn more about the entire process.
You can also judge that and vector based image is been made up by author out of whole primitives, that is lines and shapes with all possible effects applied. But complicated that image is, there’s the opportunity of getting down to those constituents as well as change any of the properties. In the raster editors it is other way and you make the stroke with brush n everything is totally lost: it isn’t the brush stroke, and it is lots of pixels not get connected to one another but having become the indispensable part of image over that stroke was made. It is like with the paper, in stone age! At present, I feel the Adobe Photoshop adepts sharpening the quills to leave the viperous comment, something about need for an author to brush the tutorial as well as learn more about the Layers, Paths as well as other stuff.
