Since you're into the subject, at the risk of repeating my other comment in this page and seeming to oversell it, I'd like to call your attention to the documentary "Dirty Pictures" (if you haven't seen it): https://youtu.be/qXHyKyoHJzo

It's mostly of historical/political interest, but I'm repeating it here because I genuinely think if you're interested and somewhat knowledgable about this subject, you really should watch it.
