Muhammad - 13 April 2012Ryan Green, Michal Winkler, Danielle Lambert, JasonThis exploration was cosufed on gaining an understanding of how artists portray the depth of three dimensions on a two dimensional plain. The first picture that was chosen was Trademark (Welder) 1935. The first aspect of art that portrays depth is the overlap of objects. This can be seen in the fact that the welder blocks the view of part of the girder, overlapping and concealing it, showing that he is closer to the viewer than the girder at that space. Size next shows us that the larger top of the girder is closer than the smaller, welder at the bottom, showing us that the perspective is higher. The next feature that shows us the depth is the shading of the artwork. This can be seen at the top of the girder which is darker than where the welder is welding. This shows us that there is a light source at the bottom of the picture caused by his welding; this shows us that the top of the girder is much farther from the welder than it appears. Lastly the perspective helps show us the depth. This particular picture has a three point perspective. Its nadir is far below the actual scene its horizon line is above the scene and its zenith is far above the scene. The second art that was seen was Delft: Voldersgracht, 1939. Overlap is seen when the bridge and pots hide what is behind them showing that they are closer. Also it can be seen that the windows get larger as they get farther to the right, showing that those windows are closer. The right facing sides of buildings always appear as lighter thus showing us that the right sides are facing the light source. It can be seen that the farther right you go the less detail there is showing that the left side is closer. It shows a two point perspective, with the horizon straight ahead, the zenith far above and the nadir far below. The next work of art that was seen was New Year’s greeting Card (Well), 1947. Overlap can be seen in the sides of the well which block out the surrounding background showing that they are closer. The hands appear larger than the house showing that they are closer. In the well it appears darker than on the outside, showing us that the light source is outside of the well. There is more detail in the hands than in the sky, showing that the hands are closer. A three point perspective is used, with the horizon line below, the zenith in the center of the sky, and the nadir is far below the view. The final art examined was Three Worlds 1955. The leaves are seen to overlap the fish and the reflection of the trees, this shows that the leaves are closer. The fish is seen to be larger than the trees, and the leaves at the bottom are larger than those at the top showing that they are closer. The water appears darker at the bottom than the top, showing that it is closer and deeper. The fish is seen to have more detail than ther leaves at the top, showing that it is closer to the viewer. A three point perspective is used with the horizon line above the top, the zenith far above the top and the nadir at the bottom of the scene.
