Paper Negative Portrait

For this assignement, I decided to use a medium format plastic Holga camera
I used the instructions from the photo technologies blog to figure out the exposure time needed.
We assume that the working F-stop of the Holga is F11 for ISO 3. I took a reading with my DSLR at ISO 400 for F11 which gave me 1/13th of a second. The amount of time needed to expose the paper correctly would be (1/13)*(2^7) which was 9 seconds.

My roommate stayed as still as he could under the stairs for this photograph. It was then scanned and inverted

A second paper negative portrait was taken, this time of Jerome, smoking outside the collecge. The same technique was used to calculate the exposure. Before the paper was loaded, it was crumpeled. Why one might ask?! Just for fun I must answer!



Now, how does this differ from a pinhole? It is much more different as (I am talking here about the Holga) it is MUCH more portable, easier to load, requires sorter exposition times. On the down side, the size of the paper used is limited and it is hard to get the image in perfect focus.

This is a Holga (not mine) (well the one i used os not even mine)
