Let's have a slide/projection subforum!!!
I very often use two projectors, a Leica P150 and a Rollei P37a during lessons to show repros of famous photographers' work, and students love the setting up ritual and the eventual reversed/stuck/wrong slide against the digital perfection of Keynote or Powerpoint prepared lessons!
