I am assuming that Photographer took your money and is not sending you the photos and videos, in that case –
Send a Legal Notice via an Advocate in Delhi to your Photographer’s home and office address.
If he doesn’t accept your demands then file a suit for specific performance (to get photos/videos) or suit for recovery (if you want your money back).
I think sending Legal Notice will suffice as of now, filing criminal complaint is useless as Police won’t investigate this matter seriously and will take years to file the chargesheet.
