the blue hour was talking about just that, the blue hour:
"At the end of a sunny summer day, there's a particular quality of light just after the sun sets. It is most pronounced if you're in a park, or in the woods, or even sitting on a lawn. It's the blue hour, the light of dusk, gloaming - but combined with green foliage in summer, it's really distinctive to me. It's hard for me to put into words - it's a feeling more than anything. I think about being a kid during summer vacations and playing outside with friends until late, summer humidity, a walk after dinner outside, cicadas, stillness, the day fading into quiet, a hush."
I know exactly what he's talking about.
And I feel lucky enough to have captured my own "blue hour" last week, though mine was taken in the early morning hours rather than at twilight.
Oh, and now it's available in my shop here and here!
