As the title implies a dawn till dusk assignment taking the same scene throughout the course of a day. In my case this was from my office window, with an ever more busy schedule this is the closest I will get to the exact requirements of this particular exercise.
Equipment used Nikon DSLR, 35mm lens, tripod. All processing in Nikon NX2 and DXO. I have a limited view through the windows (none of which are very clean) I took a number of test shots to try an find a good angle for this exercise. The camera was setup with its interval timer to take two shots on the hour and every hour from 6am till 8pm a total of 15 shots are show below:
Shame the windows were so dirty! but I still love the look of this light cutting across the grass and sides of the buildings.
The effect of the sun going behind a cloud here is clear, look at how diffused the light is compared to the previous shot.
You can clearly see the movement of the sun throughout the day and the move and angle of the shadows that it throws. In the foreground with the people and trees, but also noticeably in the tower blocks in the background. At and around mid day the shots look flat, with little to show or enhance the three dimensional properties of the scene.
Of all the shots my preferred images would be the early morning with the long shadows and the warmer light of the lower sun. The early evening images start to become overshadowed by the buildings.
