Getting to know you.

2) Do This First…An Evolving Story – Light and Color

There are many goals and many purposes for this project that you are involved with. There are many things that need to be done.

Fortunately, they don’t all have to be done at the same time.

So, if you don’t have the organizational support to download DCPs onto a USB drive and get them into the Media Player/Projector system right now – you can still download some audio and light measuring tools, then experiment with them until you can use them easily in a dark room.   Continue reading “2) Do This First…An Evolving Story – Light and Color”

It is good to have a basic understanding of frequencies and speakers and surround and amplifiers and level and Loudness. Hopefully you’ve noticed some of the many ways that the human hearing system has made things “interesting” in normal life, and while you have walked around your cinema theaters since learning more about these things.

What’s It Mean? Contrast…

Let’s go through a few terms that everybody uses, but have a specific meaning if you are going to get an idea across to the Tech Team to get a problem solved.

First, Contrast – Simply said, in the cinema, it is the range or difference between what looks like white and what looks like black on the screen. In most auditoriums, there is no real white on the screen or real black on the screen. There are many reasons for this, and it will always be. But there is a range that each room is capable of, and the equipment is in a war to try to make it stable, which it always loses. Continue reading “What’s It Mean? Contrast…”
