In this project we created a pinhole camera by taking a shoe box
and making a hole for a digital camera and a hole for the different pinhole sizes.
We used a shutter speed of 30 seconds.
This is a picture of our camera model:
The three pinhole sizes that were used were 0.6mm, 3mm, and 5mm.
Using the equation given(1.9*sqrt(f*lambda)) and since the distance from the hole to the screen was 19cm, we got 1.9*sqrt(190mm*0.00055mm) = 0.6mm.
Analysis:
It seems that the
3mm pinhole size worked the best. The smallest one(0.6mm)
was way too dim and had very dark colors. The largest one(5mm) was too bright
and since it was really bright it made the pictures very blurry.
When you use a small pinhole you are essentially confining the amount of light let in.
Since less light is let in, there isn't enough light to see a clear picture.
When you use a large pinhole you are bringing in too much light. This makes it so that
there are just bright colors and not a lot of contrast in the picture. Also since
so much light is let in, the picture becomes blurry since there is too much light being
bounced off of the white paper.
