Information and discussion on all aspects of British photographic history
I know this may not be much help as it is outside London, but the Fox Talbot Museum will be running a series of workshops on early photography in the coming months ahead. Some are listed in the BPH Events section, but for a more comprehensive selection, click here.
Mark & France Scully Osterman ran workshops in London in the past, and they are involved in the Lacock ones this year. So do check their website here, in case they have any London workshops in the near future.
Hope this helps....
thank you Michael for that information I shall check it all out.
Not London, but you might be interested...
If it helps, I came across an ambrotype/collodion Workshop running in London sometime in November this year. Details can be found here.
