As an approved photographer on stock libraries, you can possibly get access to client briefs where you can submit your work direct to the client, meaning they’ll consider you for the project and see your profile. Otherwise there’s usually a marketplace type system for you to upload your images and have them added to collections based on themes, destinations and seasons.
However, the most challenging of all the tasks involved in producing these photo films is to have the models literally become actors in the stories...not only because I want them to look the part of the betrayed lover, of the returning scorned avenger, of the famous singer haunting her past venues, but because I like them to narrate the story itself.
The other challenge is to scout for and find the locations for the photo shoots; locations that provide a "badge" of authenticity to the resulting photo films. In the the case of The Girl of Nanjing, it was the water town of Qi Bao near Shanghai....and in the case of The Legend of Hua, it was the water town of Xinchang' at some distance from Shanghai as well...while the backdrop to The Songstress of Temple Street was Hong Kong's famous Tin Hau Temple and the Canton Singing House.
Whether you're licensing photos through an agency or you're working with local businesses, destination photos sell. If you're just starting out, consider uploading your best work to sites like 500px, where you can offer your images for license quite easily. If you already have a strong portfolio of work, consider applying to Stocksy, the most reputable agency in the stock photo business. Interested in reportage?

Some of these 'singalong' parlors still exist, faded and tired but otherwise unchanged, offering a taste of popular and cheap entertainment from a past era. How these survive in anyone's guess. The parlors usually have an organist (who can also play a guitar) and a handful of habitual customers who sing Cantonese songs...and occasionally Western oldies such as "Sealed With A Kiss" by the Canton Singing House organist.
