I wouldn't expect to be able to clearly see a pattern, but photo equiptment from the turn of the century was certainly advanced enough to be able to see if the blade was shiny or darkened. It would all depend on if the photograph was a reasonable distance from a drawn blade

I not only follow your logic, but tend to agree with it. I am not necessarily presenting the argument that blades weren't etched, just looking for evidence of it.
My point about Javanese keris once receiving a Balinese style polish with it's etching was only to show that traditions can change over the years. It would be nice if we could determine with some certainty if etching blades dark was indeed always the tradition.
