This week’s theme was “Depth of Field”.
My interpretation assumes a narrow depth of field, which is best illustrated by a line of objects from near to far with one in sharp focus. The narrow depth of field is created by opening up the camera’s aperture, and carefully lining up the object you wish to be in focus with the plane of the camera’s sensor so the whole of the object is in the focal range. You can achieve many interesting and artistic effects with this method. Go out and practice!
