Are photographs acceptable in patent applications?

Photographs can be included in patent applications, but there are specific requirements and limitations. According to MPEP 507:

“OPAP may object to and require corrected drawings within a set time period, if the drawings: (F) include photographs of the claimed invention which are capable of illustration by other medium such as ink drawings, and which are illegible after scanning. See 37 CFR 1.84(b)“

This means that while photographs are acceptable, they should only be used when the subject matter cannot be accurately depicted in a drawing. Additionally, the photographs must be of sufficient quality to be legible after scanning. If a photograph can be replaced by a clear ink drawing, the USPTO may require such a replacement.
