About this project

I’ve learned a ton about optics during my photography and physics studies, but this was my first time learning about holography. Just like regular film, you need to expose the film to light, and generally the longer you expose it, the brighter the image. But the longer you expose it, the higher the risk of movement in the system, causing blur in your final image.

The film came attached to glass slides. I placed my brass rat (MIT class ring) under the slide and then adjusted some boxes so it was sitting just under the glass. I then exposed it to a red light for around 30 seconds, then turned off the light. I had tried other objects as well, but the brass rat turned out the best since it’s reflective and it increased the amount of light hitting the film in the time frame. Just like regular film development, this all had to occur in the dark. But unlike regular film development, I didn’t need to do any additional processes to develop the images.
