<span>Overlapping is when one part of a shape or form is placed in front of another, Foreshortening is a technique that make a form appear to move back in space. In Mantegna’s piece, The Lamentation over the Dead Christ, he used overlapping to provide the depth to the room, and to show the image of Christ on top of the bed. By using foreshortening, the artist was able to make the body of Christ lay horizontal, and therefore receding into the background. This technique also allowed the other figures on the left to be positioned specifically by his waist, while his chest and head appear behind the figures. Mantegna created great depth using these techniques.</span>
Answer:
1.Why is exposure a subjective decision?
Exposure is the amount of light you let in the camera to take the picture. If you let in lots of light, the resulting picture will be bright and if, on the other way, you left only a little bit of light in the camera, the picture will be dark.
Although the camera could select the perfect exposure for a given photo, to enhance most/all details, the photographer should intervene to decide the amount of the light he wants in... to control the overall feeling/ambiance of the photo. It's his photo, a second photographer might come in and make different decisions regarding the exact same location and composition. Just like a painter will approach the empty canvas its own personal way.
2.How do our decisions about aperture and shutter speed influence the photography that we take?
Aperture and shutter speed are the tools used to control the amount of light in the camera, the exposure talked about in previous question.
The best way to discuss this is to take a classic example. Imagine you want to take a photo of a fountain or a small waterfall. There is movement there. Is it better to take a photo with a very fast shutter speed to capture individual drops flying in the air, freezing the time? Or to do a long exposure to show the flow of the water? Maybe somewhere between those two extremes? All these answers are good and depend on what the photographer wants to transmit as message. That's where the subjectivity comes into play. As you play with the shutter speed, you also need to adjust the aperture to control the overall exposure of the photo.
