If the court is satisfied that there is no trick photography and the photographs are above suspicion, the photographs can be received in evidence. But the evidence on photographs to prove the handwriting can only be received if the original cannot be obtained and the photographs reproduction is faithful and not faked or false.
Lakhsmipati Choria Vs State of Maharashtra AIR 1958 SC 938.
The Opinion of handwriting Expert should not be rejected because it is solely on the photographs as the photographs must be taken to represent the condition of original correctly.
The Expert opinion is admissible only when accompanied by the data and reasoning tending to that inference.
