1- The report should be 2 pages long.
2- The report should be typed in 11-point fount, and single space.
3- The references list should be kept to a 10 sources at maximum, using whichever bibliographical
referencing style you prefer.
4- You should write a little introduction about Pinhole Camera.
5- The second thing in the paper that you should provide is a half-page narrative of the history of
pinhole cameras, including what they are, their origin in ancient times and their use during the
past few centuries. Please write this part in your own words, citing references as needed. ( it is
about History of the Pinhole Camera).
6- The third thing that you should explain how you make pinhole camera with these materials
cardboard box, such as a shoebox, potato chip can, or other cardboard tube. Make a small
pinhole at the center of one end of the box. To look at the image, cut a large square hole in the
opposite end and cover it with tissue or wax paper. The tissue paper serves as a transluscent
screen so you can see the image on it from the outside. Throwing a black cloth or coat over both
the camera back and your head will cut down on stray light. Whatever material or method you
use to make the camera, please explain clearly.
7- After that you should write one paragraph about if we look through the hole First look for the
image of some bright object, such as a halogen lamp or the Sun remember: never gaze directly
at the Sun! ONLY look at its projection onto some sort of light colored screen or wax paper.
Using the lamp bulb as an object, note the orientation of the image, as well as its change in size
as you move away from the bulb. Can you estimate how much larger or smaller the image looks
as you move toward or away from the bulb (e.g., when I move it from this distance to that
distance, how many times larger does the image get, etc) So you should write in detail what you
will see if you do what is saying above.
8- Then the second experiment that you should say in the report if you increase the size of the
pinhole a bit. What will happen to the image of the bulb? Increase the size of the pinhole a little
bit more, then observe again what happens to the image of the bulb. Now make the pinhole
quite large (say 3 or 4 times larger than it was before). What happens to the brightness of the
image? What happens to its sharpness? You should describe that in a another paragraph
9- Last thing, if we Punch 4 or 5 small holes (same size as you started out with in the original hole).
Make sure they are well separated from the original hole. Now view the image of the bulb. How
do those images compare to the image through the enlarged hole? This should be in a separate
