Photography tips

  • Photograph flowers on calm, overcast mornings to avoid wind blur and harsh shadows.
  • Get low: a shallow depth of field (f/2.8–f/5.6) isolates a bloom against soft color.
  • Stay on trails — trampling meadows kills plants and ruins next year's display.
  • Try a kaleidoscope abstract of a single bloom with our online kaleidoscope tool.
