I've recorded several dates and with some companions, we pretty much always have the camera up. I use a combination of my digital camcorder on a tri-pod and a smartphone. If she already includes a photo/video option in her rate list, I'll simply request to add video as an add-on. Otherwise, usually *after* the screening process, I'll respectfully ask if she would be open to photos or video. I'll write something like:
Would you be open to photos or video for personal use only?
When I do this, I usually let them know I would be willing to conceal their identity (exclude their head, bring a mask of some kind, etc). As rapport builds, we could expand on that as she's comfortable.
If you're looking for recommendations to get started, here are three:
Natalie: https://www.theeroticreview.com/reviews/natalie-189435
She's totally open to photos and video and practically encourages it. Not shy, by any means. lol Just be sure to mention your interest, during the booking process, so she's aware.
Aisha Love: https://www.theeroticreview.com/reviews/aisha-love-334896
She has a photos/video add-on. Highly recommended and she looks great on video. 
She's coming to town in early April, so check out her Tryst ad to get the travel dates.
Harmony Temple: https://www.theeroticreview.com/reviews/harmony-temple-357387
She has a photos/video add-on. She comes to the Bay Area every now and then, so check out her Tryst ad for travel dates or reach out to her and get screened and ask to be notified when she'll be in the Bay Area again.
Hope that helps!!!!
