This flower have so small pollen grains that they are beyond capabilities of my current optics: at this photo, we cannot see exact shape of grains (maybe, something like erytrocyt cells?). But pink color of grains is real, not casted by flower petals: when i transferred this pollen at black glass, grains still looks pink on camera screen.
Gear: my usual “snowflake” macro setup (i described it in article about snowflake photography). Daylight from right side, reflected from opposite side with aluminium foil.
Focus stacking + averaging (12 groups with different focus, each group contains 10 identical shots for averaging). For background i averaged all 120 source RAWs for better smoothness of color gradients with no visible traces of noise.
