1) This is a picture I took while walking back to campus from Piazza Navona. I really like how the shadows make the buildings look so cool, and the colors of the buildings and the sky contrasting with the dark of the shadows gives it a really powerful feel. I have been so interested in going to different places at different times because seeing things with different shadows and coloring gives them an entirely different feel.

2) The ISO number refers to the films sensitivity to light. The lower the number, the less sensitive the film is so the higher the numbers get the more sensitive the film gets. This means the low number and low sensitivity film requires more light exposure for the film to produce the image. It is recommended to use a low ISO to avoid getting the blurry effect that sometimes accompanies the higher number ISO.

3) Louis Jacque Mande Daguerre was a French artist and physicist credited with creating the daguerreotype process of photography. The daguerreotype was mainly used for portraits and resulted in one unique image. He used silver salts to produce images by using a silver plated sheet and exposing it to vapor given off by iodine which resulted in silver iodide coating the sheet. Then the plate was exposed to the camera to produce the image; he made this process faster by producing the image on the plate using chemicals to speed up the reaction (mercury) and by removing the excess silver iodide.
