This image, captured in 2016 at Great Sand Dunes National Monument in Colorado, holds special significance for me. Presented as shot with my old iPhone 6s using the now-defunct 645Pro app, it represents a pivotal moment in my photography journey before I transitioned to a DSLR camera. The black-and-white composition emphasizes the sweeping dunes and expansive sky, beautifully highlighting the unique landscape of the monument and evoking a sense of wonder and nostalgia. All "effects" done in camera.
