After I posted my last musing, many more examples of photography department directors appearing in films were brought to my attention by MN Sardana and Yaseer Abbasi as a response to my Facebook post. Thank you both very much!
1. Singapore (1960): Dwarka Divecha, Shammi Kapoor, Agha Shapur
2. Solvan Sal (1956): Anil Kumar, Kammo, Dwarka Divecha, Mr Raj Khosla
3. Abhiman (1973): Jayawant Pathare (right)
