You shouldn’t “use” generic to fix any specific problem, you should create a new Ref Type to handle your specific needs for a ref type like Photograph.
To learn about creating or modifying Ref Types (about page 11) See [https://support.clarivate.com/Endnote/servlet/fileField?entityId=ka11K000000ONtTQAW&field=CA_Attachment_1__Body__s](https://support.clarivate.com/Endnote/servlet/fileField?entityId=ka11K000000ONtTQAW&field=CA_Attachment_1 Body s)

Then apply that Ref Type to your record, and ensure you create a Bibliography Template for that ref type in your output style. If you don’t use artwork or maybe film, for another record, you might start with that, rename and modify the field names to make sense. You can use the text [Photograph] as a part of the title field, or adjust the output style template to introduce that text to all photographs.
