Denise and I made an unplanned side trip on Saturday to the Thomas Edison National Historic Park in Orange, New Jersey. They don't allow tripods of any kind at the museum so I had to improvise and shoot the entire inside set of photos in the factory area using my iPhone 5S and Procamera app.
This is the second floor machine shop. The second and third floors were a treasure trove of historical industrial engineering subjects. I only wish I could have used a medium or large format camera with a sturdy tripod up there to capture it properly. I still like the results I got here. I do want to return soon since we arrived late in the day and only had an hour and a half to wander around before they closed for the day.
