Hi again folks, It now seems that the signature on the bottom corner of this hand tinted photograph of the above couple has been added to the photograph after it was hand coloured - presumably not by the photographer but by the artist who coloured the black and white photograph after completing the job. I have contacted Hugh who can not find the name Carlyle amongst the names of photographers in India during the early 1900s. It may well be the name of an artist in NZ, who was given the job of hand colouring the photo prior to it being framed to hang in my grandparents' front parlour in Invercargill. NZ. My next search is to see if the original photo has a photographer's stamp of signature somewhere on the original photograph but that's in NZ and I'm in OZ. Thanks to all who sent me suggestions, Cheers Ainslie.
