Alberti

"For this reason always take from nature that which you wish to paint, and always the things will turn out more beautifully." Alberti's understanding of painting can be summarised with the previous sentence because he says we should draw what the eyes see. Also dividing the painting process into three parts, Alberti makes it easier to reflect nature but he insists on not to draw the ugly things. Instead of showing the disabilities in your picture, make the angle right and reflect it successively.
