The picture shows a close-up of the keyboard of a laptop, which is illuminated by warm rays of sunlight from the background. The screen of the laptop is on the left edge of the picture and a woman in a dark blue shirt can be seen sitting in a blur on the right edge. Her hands are resting lightly on the keys of the laptop. The background of the picture is very blurred, but you can easily recognise the walls of a room and a window through which the sun's rays shine.
