I often enjoy going to exhibitions unprepared as that can give me a cleaner sensory experience than having read reviews; such was the case for The Shape of Light at Tate Modern.
There is something about Minimalism that resonates deeply and here are some of the pieces that stood out for me: part of Alison Rossiter’s expired photography paper series
Barbara Kasten’s cyanotypes 
Edward Ruscha’s parking lot photos next to Carl Andre’s Steel Zinc Plain
Black by Inge Dick (the people and shapes are all reflections)
One of Jay Defeo’s Untitled pieces 
John Hilliard’s Seven Representations of White (with more reflections)
and, seen at the end, Thomas Ruff’s massively scaled virtual photograms
