Overview
Project Physics is a pinhole photography project that incorporates advanced laser cutting technology. It focuses on creating pinhole cameras made out of plywood that can be used to capture stunning and unique images. The use of laser cutting allows for intricate and detailed designs that enhance the aesthetics of the camera.
In this six-week course, three high school students attempted to become photographers by exploring the vast world of pinhole photography. Through the incorporation of design and photography skills, as well as testing their patience, creativity, and problem-solving abilities, the final product is something they are proud to share.

Analysis
We found that the biggest factor affecting resolution and detail was the size of the pinhole. Another significant factor was surface stability. We often had to take pictures on windy days and had to ensure that we found a flat and solid surface before capturing an image. To improve resolution, we also experimented with using very short exposure times and leaving the image in the developer for a longer period. However, this approach made the image more 'blotchy' rather than enhancing its level of detail.

Analysis
The depth of field trick was something we identified early and wanted to take advantage of. Being able to take a picture with multiple layers entirely in focus was a special effect in itself. The best part is, there isn't anything extra we had to do to get the depth of field. We just had to design a camera with a high enough F/stop.
Portraits were definitely difficult. We very quickly realized it was incredibly difficult to stay still for periods longer than five seconds.
Special Effects Cont.
Selective Masking
Using filters, parts of the film are left unexposed. If done correctly, the final image is two alternating images.
Consecutive Developing
By sealing off a certain part of the film, it is unable to develop. If it is developed at a later time, parts will appear darker than others.
Silhouette
This effect utilizes exposing the film multiple times in different places. This creates an overlap in the images.
Improvements
Kunal Bolta
- Lighting is impressive!
- Try leaving your film in the stop bath longer to prevent the yellowish tinge.
- Decrease the pinhole size to increase resolution.
- There seems to be a little bit of movement or light leak in some of your pictures. Recommends running a control where shutter is not removed.

Technique: Laser-Engraving
After heavily modifying the original image, I was able to engrave on 1/8 inch plywood. This took a few iterations, because the original image was too dark to successfully engrave.
