First Photographic Emulsions Exposure Time?

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all! I need some help with this.

What were the average exposure time of the first photographic emulsions?

 

Few days ago I noticed something interesting in the “Genious of Photography” documentary.

The said emulsions exposure time was so long that people on the streets barely registered on the film, if they did at all.

I plan on duplicating it with modern means but I need a reference point. I guessimate 2 minutes? Or is this too long?

 

BTW let’s assume that lighting conditions are late afternoon of a sunny day.

 

Thanks beforehand, Kostas
