Pin Hole Camera Lab Report

Pin Hole Camera Lab Report
PURPOSE:
     The purpose of this lab was to be able to take pictures of objects in negative using a pin hole camera. We needed to learn how to build the camera and be able to make it work. We needed to discover what happened to the picture and why it turned out the way it did (upside down, backwards, e.g.).

MATERIALS:
  • Scissors
  • Duct tape
  • Cardboard box (cylinder)
  • Pin
  • Small aluminum square (pin hole)
  • Sandpaper
  • Black paint
  • Paint brush
  • Photographic paper
  • Chemicals to develop picture
PROCEDURE:
     1)We began with picking out a cardboard box and receiving all the materials to make the pin hole camera.
     2)Next, we taped all the holes and corners of our boxes to make sure no light got in. Also, we made a lid for the box. Next, we painted the entire inside of our box and lid black and cut out a dime sized hole in the side of the box.
     3)Then, we sanded down a small piece of aluminum (with the piece of sandpaper) from a pop can so we could put it over the dime sized hole.
     4)Next, we taped the aluminum piece on the cardboard box. We also created a cover slip made out of duct tape to allow the box to be completely black on the inside. (Reasoning is to put the film paper in the dark room and take off the cover slip to take the picture)
     5)Lastly, after everything in creating the box had been finished, we were ready to begin taking pictures. We put the film paper in the box while in the dark room so it does not ruin the picture. After that, we had chosen a spot to take a picture at and took off the cover slip and left the pin hole camera in the same place without moving it for a couple hours (depending on the lighting).
     6)After the picture had been captured, we carefully put the cover slip back over the pinhole and went to develop the picture in the dark room. (Developing involves putting the film in multiple chemicals to start and stop the developing and finally in water to clean it.)

CONCLUSION:
     During the experiment, I had learned many new things on how a pinhole camera works. The hole allows minimal light to enter the box and allows the film paper to be able to develop into a picture. The amount of lighting affects the picture taking process greatly. For example, the more natural sunlight/light in general, the faster the picture will be taken. However, we had to be careful not to leave the camera exposed for too long, otherwise the picture would turn out black because too much light had gotten in. Also, if not enough light had gotten into the camera, for example in a room with minimal light, the picture will not show up very great either. We had discovered that if any light had seeped through any cracks in the box that hadn't been sealed, the picture would have been ruined.
     After we had developed all the pictures, most of them were successful, with the exception of 1 or 2. I had altered a few things such as the place where I had taken the picture. Changing the place of where I had taken the picture gave me the opportunity the play with different amounts of lighting that the camera had let in.

Rock and Roll Hall of Fame Overview

Rock and Roll Hall of Fame


     On our physics trip to the Rock and Roll Hall of Fame and Museum, i had learned many new things. We had attended a class where a woman had taught us how musicians would record their music and how it changed over the years. She had mentioned the use of echos to create a different sound in recordings. She had also talked about the uses of synthesizers and how they made a huge impact on the way artists recorded their music.
     After the class had eneded, we began our own separate tour of the museum. We went to the upper floors first and observed many portraits of musicians from the 1900's. Then, we traveled back downstairs to listen to the different types of "one-hit-wonder" songs they had on display. They also had a display in a room with all of the inductees' signatures which was very interesting and neat. We ended with going downstairs to the basement level and going through the different displays and observing the clothes of artists, their cars, and their own style they put into their music.
     I had come to the realization that there are many more artists that I know that had been inducted into the Rock and Roll Hall of Fame. It was a fun experience and I would do it all over again and return there with only one change; more time.
