A quick reminder because I love getting myself distracted by photo challenges: The 2/3 series features a simple formula: composition by the so called rule of thirds. The idea is to focus on structures and colours rather than composition while giving the pictures a uniform look. Based on this unifying ‘grammar’ it should be possible to arrange and re-arrange picture series according to different criteria – and tell different ‘stories’ – without losing a certain coherence. Here, the story told might be of rocks, or the remnants enclosed inside them.

Ich finde es unheimlich gelungen, wie du die unterschiedlichen Strukturen fokussierst.
