Great filmmakers should never let a lack of funds get in the way of an epic project. If you're searching for a piece of equipment to give your film a polished edge, look no further than your garage. A car can supply that extra professional look without costing extra professional dollars.
Attention Filmmakers! If you are sitting around, twiddling your thumbs, waiting for that perfect budget to fund your movie, look no further! Seriously, stop looking. It's time to quit procrastinating and use that crafty mind of yours to make your movie. As long as you have a camera, a friend, and an idea, you're ready to get started.
I discuss ISO and other related topics (aperture, shutter speed, histogram, and so on) in my recently completed an introductory photography book: "A Concise Introduction to Photography."
ISO is a measure of the sensitivity of your film or digital sensor. In this episode I discuss the basics of ISO and how it relates to exposure and noise.
