sepia???

[stan the man]

whilst in a digital photography/imaging manipulation course today,the subject of sepia came up.no-one seemed to know how/what/where it originated,ie:was it due to the process of developing film in years gone by,or was it the best/nearest they could get to colour photography?

thanks in advance

I think originally it was used to prolong chemically the life of b/w images, when in the early days the pigments used would fade after a while, sepia kept its tone.
This could be rubbish ^ I'm not sure
If they wanted colour, they would hand paint them with water colours or something.

no its true sepia pigment was obtained from cuttle fish it turns any silver into a sulfide & is more resistant to aging. A B&W would last as long in same conditions. now just adds a touch of age.

not that clever i googles it lol
