I have not an art education. But very much I like to draw. I draw always when there is such possibility. Small drawing, quick sketch. In the future they will become ready work, which I place on stocks.
In process of preparation of drawings for stocks I used the technics of vector drawing which I want to share for you.
The sketch demands the further processing in the raster program, for example a photoshop. Scan the pencil drawing, increase contrast and black color intensify a contour. Turned out image trace in a vector. Further long and boringly - clean superfluous points and smooth bends. A work result - picture-coloring.
Begins the creative activity. Much colors, little lights, little shades...
And some imagination.
Possibly such method will be useful also to you.
