What Happened: Yesterday during lunch we got to develop the photos we exposed. We turned Andrew's room into a dark room by covering up the door, turning off the lights and using a red light. We put trays of fixer, developer and stop bath out. First Andrew cut of a piece of one of the photos out and put it in the developer to see how quickly the negative would show up. We slid our photos into the developer then the stop bath and lastly the fixer. It was so exiting to see the photos slowly develop. But unfortunately we did not get desirable results our photos turned out looking like gray swirls and you couldn't make out any of the actual shapes from the things we took pictures of, that is not uncommon for pin hole cameras. Andrew did tell us that we did expose our pictures right because they did not turn out completely black.
On a Molecular Level and Science Take Aways: The way the pin hole camera works is when light shines the photo paper, the light is absorbed onto the paper creating an exposure. But If the surface of the object is not perfectly smooth, the reflected light is bounced off the object at many different angles. Light rays reflected from an object may be thought of as originating at the object. The camera has a pin hole size lens so that it will just capture a small portion of light so that it can distribute that light forming the image. Opening the shutter just captures the light where ever you point it at and when you seal it back up the light is shut out leaving the paper with a single exposure. For the developing process the is film is first submerged in developer that is a reducing agent. The developer will convert all the silver ions on the photo into silver metal. Those grains of silver metal have image sites will develop more rapidly. The unexposed grains will remain as silver-halide crystals. The halide crystals that form on the photo is what creates the negative from the light. The next step is the stop bath which is used to stop the silver metal on the photo to stop forming so that the photo does not get over exposed. Basically washing off and neutralizing the developer. It is made up of alkaline. The stop bath also helps control the fixer. You do have to ware gloves while handling it other wise you could get chemical burns. Next, with the fixer the unexposed silver-halide crystals are removed. The fixer dissolves only silver-halide crystals, leaving the stabilized silver metal behind. The silver metal remaining on the photographic film or photographic paper, leaves behind the reduced metallic silver that forms the image. The image you get is a negative of the original scene. The photo has the highest density of silver atoms in the area that was exposed to light the most. In places that received no or less light, the negative has less silver atoms and is looks more opaque.
Lab Practice: I think Maia and I got undesirable results because we exposed our pictures too long in a bright sunny area. The instructions we looked at said to expose them for 30seconds to 4minutes and we exposed both of our photos over 4 minutes. Although it is difficult to guess exactly what went wrong, because the process is very tedious and there is a lot of mistakes that could be easily be made. It could have also been a bit of light came through other parts in the box, that would explain the swirly look of the photos.
Collaboration: I think that Maia and I collaborated very well in this lab we did have quite a bit of confusion throughout this lab because we didn't now exactly what we were getting into. The only thing was that we needed to communicate and research more in the begging so that we would now exactly what the process would be. We never got frustrated out even though it was challenging to always be in a dark room. We worked together and figured out what to do.
What Next: If I could do this again, Maia and I would get a box that was more light proof and I we would try too take a shoot inside so that there would be less light over powering it. Just try new things and see what exposure would turn out the best. I would defiantly may continue this lab it was really interesting to me because I am really into photography of all kinds. I never thought that I would have the opportunity to develop pictures with a 'camera' that I made and develop them my self like when cameras where first invented. It was a really cool experience and I learned concepts that I would have never learned about otherwise. This lab was really amazing and although I would really like to develop a successful negative in the future.
