This Tuesday at the Discovery Science and Technology Centre, the group of girls explored a fascinating photography and filmmaking technique known as forced perspective. This method manipulates the size or position of objects to create distorted or illusionary effects, playing with the viewer's perception of depth and scale. As a result, objects can appear much larger or smaller than they really are, or spatial relationships can seem unrealistic.
After watching a short video that explained the theory behind forced perspective, the girls were paired with students from another school. They were given iPads, some props, and encouraged to experiment with the technique. Within minutes, they returned to the lab, eager to share their creative photos. It was inspiring to see the girls' imagination and creativity at work as they captured their distorted, playful scenes.
Next, the girls learned about chroma key, another popular technique used in film, television, and photography to create the illusion of a different background. The process involves filming or photographing the subject in front of a solid green (or blue) backdrop, and then using software to replace the green with a new image or scene in post-production. They discovered that while colours like red, white, and black were once used as backdrops, lime green is preferred today. The colour does not match skin tones, is not commonly used in clothing, and is easier to remove digitally, making it ideal for creating virtual backgrounds.
To wrap up the session, the girls were rewarded with a playful activity involving a sticky insect. The reactions were mixed, some found it hilarious, while others cringed as it landed on their backs. It was a fun and memorable way to conclude an afternoon of learning and creativity.
