With iPhones continually advancing their camera capabilities, one can capture satisfying photos without the need for a dedicated digital camera. Yet, there exists a niche of individuals who intentionally purchase older digital or film cameras. They are drawn to the unique aesthetic of photos and videos produced by these cameras. In this talk, we'll explore how to achieve such retro-style photos using Swift. While Core Image's documentation offers articles like "Simulating Scratchy Analog Film," implementing these techniques directly into a camera app may not yield the desired retro effect. Therefore, we'll start by reexamining the question, "What defines a retro-style photo?" and aim to create the ideal retro aesthetic. Speaker: Yunosuke Sakai try! Swift Tokyo Conference 2024 - try!
