From what I've learned from this discussion (from those who properly contributed), I would agree with you. I think if my goal was to make money off those photos, then I should be hiring models for the explicit reason of doing so. But, that's not really my goal, so I've concluded to just post my favorites from TF shoots on Instagram, and then just have a private portfolio for when people want to see the rest of my work. Again, the disconnect for me is that I'm used to always saying, "check out the rest of the photos on Facebook," so I was trying to find an alternative. The alternative, I believe, is just to not post them all.
