Some of the details and colour intensity of the photos are simply amazing considering is 100 years pass. You could imagine what they looked like when they were freshly taken.
The funny thing about photography is that the medium keeps being completely reinvented every so often, but the lenses and body configurations are generally conserved over time.
I would love to snap some those 100 year old lens designs on my digital to see how they stack up against some of the consumer zooms being made today
