NPS recently announced that the peak bloom for cherry blossoms in 2015 in Washington DC and the Cherry Blossom Festival is April 11-15 2015. You can read more on the National Cherry Blossom Festival or NPS website.
The past few years have flipped between peaks in March and April. This picture is from March 2011, when the following morning I captured my most popular image, Awakening. I passed by this image for years and finally decided to process it… I actually like it quite a bit since it shows the Cherry Blossoms in a bit different scene – under twilight and stars. I spent a bit of time dodging the stars so they would come out brighter – so I would consider this image as one where I took some fine art liberties.
