There could be a number of reasons why your photographer is not listed on this site.
They could include the following –
- they were not a professional – i.e. they were an amateur photographer
- they did not operate at any time before 1940
- they did not have a studio IN THEIR OWN NAME – this can happen if they owned a studio such as ‘West Street Studio’ or ‘Abbey Studio’ etc.
- their business name was ‘Brown Brothers’ or ‘Williams & Son’ etc.
- they worked for someone else as an employee – this could be in a portrait studio or for a news agency or perhaps they travelled around and took photographs for publication as postcards
- they worked under an assumed name (not as infrequent as would be imagined).
