Pinhole Reflection- Alison & Karina

Karina's Reflection:

 

Alison and I worked on making a pinhole camera last week.  We made a pinhole camera out of a Pringles can, tin foil, and light-sensitive paper.  Once our camera was completed, we inserted the paper.  Since the paper was light sensitive, we had to put the paper in our camera in a room with no lights except two red lights.  We went in the light-proof room with 3 other groups and attached the paper to the lid.  We had to be extremely careful about covering our camera because if light reached our paper before we were ready to take a picture, it would ruin it.  In the room we had to cut the paper to fit the inside of the lid and put the paper back into the bag before we could turn on the lights.  It was a time-consuming and intercut process, but after a while we got used to the amount of light in the room and were able to work faster.  Once our camera was loaded with film, we went out with the other groups.  We went outside because that is where the most light is.  Luckily it was a sunny warm day and there was a lot of sunlight.  Alison took a picture of me from the same angles and at the same place four times.  The first time the paper was exposed to light for 5 seconds, the second time 10 seconds, the third time 15 seconds and the fourth time 20 seconds.  After each picture, we had to go back into the dark room and reload our camera with new paper.  After we removed our used paper, we had to place in into a bag with all the other pictures and we had to seal the bag to confirm that no light would access the paper.  We were testing what amount of time makes for a good picture.  I think the 10 second picture will be the best because the time was right in the middle.  The only problem with the pinhole camera was that when Alison was taking the picture she could not see what she was taking a picture of, so she had to guess and hope that it was pointing to where she wanted it to point.  Also, since we had to keep going back into school and relaod out camera, the sun probably moved and the angle of the light slightly changed.  In conclusion, it was great experiment.  I learnt a lot and it was extremely fun; I just hope the picutres turn out good! 

 

 

 

Alison's Reflection:

 

Karina and I worked as partners on this project and we spent last week making the camera and on Monday we did the experiment. We went into the black room with two small red lights, it took a while to prepare the cameras because it was so dark. We had to take light sensitive paper from special bags and cut and label it. then we put the paper inside the camera and made sure the whole camera was covered with tinfoil so that no light would ruin the paper before we took the photo. Then we went outside and took photos of Karina. We took 4 photos in total. The first we left for 5 seconds, then 10 second etc. up to 20 seconds. When we get the photos back we hope to see what amount of time creates the best pictures. after we took one photo we had to go back into the room-with-no-light along with three other groups and take out the used paper, but it in a special black bag and then redo the process until all four photos had been taken. we wnt outside to take the photos because we wanted the best abount of light. We took the photos of Karina on a really sunny spot of grass in hopes that we would be able to see her better. The major problem we are worrying about is the fact that we might not have actually take a picture of her. I was standing really far away so it is likely that I got her in the picture but because there is no way to see what we are taking a picture of we can just hope that the camera was pointing in the right direction.  My hypothesis was that 10 seconds would make the best picture, and I cannot make a conclusion at the moment because I have not seen out pictures.
