So the first thing when it comes to projection blending is, it’s as easy as you think about it. There is this diminishing law of return when it comes to the brightness of projectors. So I want you to just kind of keep that in mind as we talk about putting projectors on top of each other to make them double as bright and things like that. Projection Blending: Double-Stacked Projector That’s where we might want to look if you need it to be brighter, it needs to be outdoors, you might want look at led screens, things like that. So one thing to keep in mind is that even though you might say, “Hey, I’m going to throw a ton of projectors at this problem and make it brighter.” There is definitely a diminishing law of return. And what you perceive as bright when it comes to projectors. Well, once you start to get into that 18K, 21K, 30K lumen area, you start to see this diminishing law of return when it comes to brightness. You might see only a bit, a little bit more of a return. But then you go from a 3K to maybe a 5K, or a 6K, you’re doubling again. You’re going to see a big bump in brightness, what you perceive as being bright. The important thing to know is that at some point, yes, you’re going to see, for example, if you go from a 1K, 1000 lumen projector to a 3000-lumen projector.

And then we have the perceived brightness over here on the X-axis. We have light intensity up on the Y-axis. In fact, you get this sort of graph here. So one thing to keep in mind though is that perceived brightness, what your eye perceives as bright, is not equal to the number of lumens projected in the brightness of that projector. Well, obviously if you subtract those, it tends to make the projector dimmer on there. You might hear something like a 10K projector, or an 18K, projector, 21K projector. So you may know this, the brightness that’s outputting from the projector is measured in lumens. Click out, click out, click out.” I want you to pause for a second and we’re going to talk a little bit about the idea of brightness not equaling the same thing as the lumen projectors on projectors. And before you go, “Oh my gosh, graphs, math, get me out of here. So before we dive into it about the different types of blending and some basics around it, I want to talk about this graph right here. And kind of how this works, and why it’s important when it comes to your AV setup. And for people in the events, just to make sure you understand a few basics when it comes to projection blending. What I thought it would be interesting though is, I think that there’s not a lot of education for planners. But obviously we’re going to listen to what our clients tell us to do to save money. We wish it was brighter.” Obviously, as an AV company, we regret allowing them to do that. And onsite they said, “Oh my gosh, it’s not bright enough. Because we had these nice 30 foot by 10-foot screen screens on either side, very awesome looking corporate setup.” And they ended up getting rid of that. We’re going to end up not doing double the amount of projectors. I had a client who decided, “Hey, we’re not going to go with our backup projectors. This came after essentially this last week. Why You Need To Know About Projection Blending I’m going to explain some basics that will help you understand this a little bit more. Oh my God, click out.” No, don’t do that now, even if you don’t know anything about projectors. Well, that might sound confusing and technical. And today we’re talking about the basics of projection blending. What’s going on everybody? Will Curran from Endless Events back here again with another Whiteboard Wednesday. The Basics of Projection Blending – Video Transcription And what event planner doesn’t want that? So press play and let’s get to this week’s edition of Whiteboard Wednesday! Either way, you’ll learn something that can make your events better. So join our lovely host Will Curran while he walks you through the basics of projection blending.

And that includes AV and, you guessed it, projectors! At the end of the day, the success of your event is the sum of many things. Because event planners do need to get educated on certain aspects of AV. It’s about time you get a crash course on projection blending! But seriously, even if you don’t care about projectors or want nothing to do with it – stick around.
