The requirement of this exercise was to provide a single image with an emphasis on illustrating rain. The image could be generated for purpose or captured in the wilds... I chose the wilds.
The umbrella is a relatively universal interpretation of rain, however in choosing this image I felt that the element of rain has been more positively transmitted into the conscious understanding. The inclusion of the car with it's rain drop covered roof enforces the message with its more graphic and less interpretative presence. If the image presented umbrellas alone then the message may have not been so overtly about rain, just inclement weather.
The depth of field selection, with the focus area being toward the nearer car roof, renders the umbrellas in the distance into a blur, and therefore a component of rather than the whole of the image narrative.
