PinHole Photography
Making your camera
To make my pinhole camera I needed a tin that was or could be made light tight. I then had to paint to inside with matt black paint. Once I had done this I had to drill a hole into the side of my tin the cover it with tin foil.
After doing this I had to pierce a hole in the tin foil with a pin, I then had to make a flap out of cardboard to hold in the light and let the light in to take photos.
Preparing your camera
To get my camera ready to take photos I needed to cut and shape some photographic paper to fit the inside of my camera without covering up the lens.
I had to make sure that my photographic paper was secure with masking tape so that it didn’t move about and ruin my pictures.
To calculate how long I needed to keep the flap of my camera open, I needed to calculate the Fstop.
Lens
Measure from lens to back of camera.
Pinhole cameraThis required me to measure the point form my lens to the back of my camera.
After taking the measurement I then had to divide it by the size of the pinhole on my camera (aperture)
Focal Length
------------- = Fstop
Aperture
90
------ = 112
0.8
This means that to take a picture on the inside of a building, depending on the light readings we took earlier on in the day I have to expose my photographic paper for 15 minutes
To take a picture on the inside I have to leave it out for 40 seconds.
Taking a picture
To take a picture I need to choose a location put my camera in a suitable place where it won’t wobble or be unsteady and open the flap and leave it for the designated period of time.
