Ohio Rev. Code § 2317.41
"Photograph" as used in this section includes but is not limited to microphotograph, a roll or strip of film, a roll or strip of microfilm, a photostatic copy, or an optically-imaged copy.
To the extent that a record would be competent evidence under section 2317.40 of the Revised Code, a photograph of such record shall be competent evidence if the custodian of the photograph or the person who made such photograph or under whose supervision such photograph was made testifies to the identity of and the mode of making such photograph, and if, in the opinion of the trial court, the record has been destroyed or otherwise disposed of in good faith in the regular course of business, and the mode of making such photograph was such as to justify its admission. If a photograph is admissible under this section, the court may admit the whole or a part thereof.
Such photograph shall be admissible only if the party offering it has delivered a copy of it, or so much thereof as relates to the controversy, to the adverse party a reasonable time before trial, unless in the opinion of the court the adverse party has not been unfairly surprised by the failure to deliver such copy. No such photograph need be submitted to the adverse party as prescribed in this section unless the original instrument would be required to be so submitted.
