I tend to view this photograph on the basis of compositional elements rather than the rendering of highlights, shadows, sharpness of the included elements or of the type of broom that this is.
For instance this image is all about shapes, lines and textures to me...the “photography of known and readily identifiable objects” really has very little interest for me today.
The first thing that I notice is the mimicking of the diagonals in this image. By that I mean the diagonal shadow on the door mirrors exactly the angle of the diagonal of the broom handle. The curves of the vegetation on the left wall mirror the curves of the vegetation on the right wall. The lantern on the larger right wall surface contributes to resolving the relative imbalance seen in the smaller left wall surface. Furthermore the lantern is located at the point of interest of the upper right hand corner and it serves as balance to the location of the broom which is located in the lower left hand corner "point of interest" of the image. Last but certainly not least is the source of light deep within the composition that is rendered as the window located in the interior of the room. This source of light located deep within the image imparts the dimension of deep space in the composition. For me, the single greatest point of compositional tension within this image is the point at which the diagonal of the broom handle impinges upon the vertical line of the wall.
These are the things that I see that make this image effective and worthy of being called a fine photograph today after the passage of all of this time. I care nothing for why Talbot chose to photograph this scene…I don’t care whether he had cornflakes for breakfast or whether he had sex the evening before.
