Re: [frameconnews] Identification of photo process

[Mitch Park <mfpark@xtra.co.nz>]

Thanks for replies received on the "Mezzotone" topic. However, there is
no 
doubt that this item is a normal photographic portrait from a
professional 
studio and that the printing press had nothing to do with its making. 

Having re-examined it and looked through the PPFA volume on photography,
it 
seems probable that this print is simply a normal (for the period) matt 
collodion, with appropriate toning to make the shadows look a dark
chocolate 
brown. The carbon print ridging effect is missing and there are no signs
of 
cracking in the dark areas.  

However, that was also the case with another portrait from the same
studio, 
twenty or thirty years older and clearly labelled as a carbon print. 
Hence my 
question as to whether "Mezzotone" identifies a carbon process picture.

Still in the dark.
