The blue background with the blue dress sounds really cool! I hope the photos come out well enough that you decide to show them to us. Can't wait to see!

If the program really helps with the planning of the lights, 150€ is a bargain in my opinion. Otherwise can't imagine how only one hour could be enough. Although you have a teacher there so that helps. And you are not yourself totally clueless either I might ad. But still, only one hour! Terrifying! :)
