It's worth more, more often than you think, it's just hawked by random "influencers" with a paltry 50k followers or some shit. That kind of exposure is worthless.

I've heard from photographers and artists before that they will consider exposure offers, but only if you have an actual status. Like a major brand or near-celebrity or a top 50 social media "influencer" with millions upon millions of followers.

And they usually want a contract, i.e. you have to pin our work for X days and you have to tag us etc.
