The area of sharpest focus in a photograph (B)

Explanation:

Depth of field: when you focus your lens on something you’re actually focusing on a plane. There are some exceptions but mostly the plane is parallel to the sensor when you want to focus further away you turn the focus ring, and the plane moves further away. The furthest that you can move is infinity focus. This is the distance after which it doesn’t matter anymore because everything beyond that point will appear to be in focus  

the above mentioned statements talks about the creativity of an artist and to what extend they can utilize and experiment on the objects provided.   differing size and subjects are given so that an image of wisdom is created. displaying a transition from light to dark in something by darkening sections in order to create a shadow. and lastly, putting bits and pieces together to formulate a new image.
