February 1936. “Mission District. San Francisco, California.” Medium format negative by Dorothea Lange (1895 – 1965) for the Resettlement Administration. – Shorpy
Dorothea used the Graflex Series D to take her photographs. The lens came standard as a f/4.6 anastigmat lens with a focal length of 7-1/2 inches (190mm) – 4×5 camera. If you just take a quick look at this photo you may dismiss it .. that would be an error in my opinion. I decided that it would be cool to try and model this structure .. at least as a low-profile structure and that it might be fun to walk through what I did to bring it back to life in model form.

The following is taken from History of Yard Lumber Size Standards
The photo we are attempting to get measurements off of was taken in 1936. Looking at the weathering on the building it could easily have been built c. 1900 .. so a 2″x6″ board may very well be the full 2″x6″ and not the 1-1/2″x5-1/2″ we would find today. In fact .. it could be whatever was needed at the time if cut locally.
