- This is my first "First Sunday" project. A soon to open Iris bud stands among the tall green foliage. Snapchick issued a challenge on the first Sunday of each month to focus on composition and creativity rather than high tech camera gear. The challenge was to use your oldest digital camera, set it on a high ISO and a low resolution. The idea is to show what the photographer can do rather than what the camera can do. This photo was taken with my first DSLR a vintage 2003 Canon Digital Rebel aka 300D, 1/2000 sec @ f/5.6, ISO 1600 (the camera's highest setting) using a 50mm prime lens.
