to blend, mix together.
For years I have been making photographs that take fractions of seconds or minutes to hours to expose. I recently decided to blend two images taken with the same camera a week and 6hours apart.
The image on the right was 6 minutes in mid day sun.
The image on the left was 12 minutes in late afternoon sun.
The central portion of the image was both 6 minutes and 12 minutes
Remnants of the week before remain in the image, and new artifacts appear, but most of the world remains the same. The trees swayed in the breeze, the fence and signs, remained. The white streaks from headlights that passed by virtually unnoticed appear as whips of light.
