Introducing Media to your Church Part 3:The Projector(This is Part 3 in a series. To begin at the beginning, go
here)
One projector, two projector, three projector, four? While four would be very cool, one or two will do. Whether you start with one or two depends on the size of your church and wallet. If you're small or portable or have a nice central place for a screen that everyone can see and read, then one is what you want. If you have a big sanctuary/auditorium with people sitting out to the right and left sides of the stage area, then two would be best.
As you start hunting for a projector, you're going to be bombarded with all kinds of specs. Pixels,
Lumens, Contrast Ratio, Aspect Ratio, etc. Again, don't let all the technical
mumbo jumbo get you down. There is some important information contained in the spec sheets. But what you need to know can be easily understood. So what is it you need to know?
LUMENS:
Lumens is a fancy word for brightness. How bright is bright enough? This, I think, is the most important consideration. A projector that's great for PowerPoint presentations in a conference or meeting area isn't necessarily going to be bright enough to use in your sanctuary. Your projector needs to put out enough light to cover the distance between it and the screen, be bright enough to overcome whatever ambient light exists in the environment, and has to display an image that can be seen by people from anywhere in the room.
When you go to the movies, the film is projected in a blacked out theater. When you go to church, on the other hand, there tends to be a lot more light present while the projector is being used. A lot of churches have windows. The stage is usually lit for worship or for the message. Oftentimes, there's a general light level maintained in the sanctuary for note taking, reading, etc. This light in the room, the light the projector has to be bright enough to overcome, is called ambient light. Your projector has to be bright enough to overcome the ambient light.
So how many
lumens do you need? It depends. Price is going to make you want to go for something in the 1100-1500 lumen range. These projectors can be a good solution for small churches meeting in relatively dark rooms. But for churches bigger than 100-150 people or for churches meeting in a bright environment, 1500
lumens isn't going to do it for long. If you're only using PowerPoint and still images and you're able to keep the ambient light level low, you might be able to get by for a while, but the minute you want to start showing videos or movie clips, you're going to notice. Your video clips are going to come out looks dim and milky. In other words, they'll be hard to see and washed out looking. To be safe, I wouldn't purchase anything less than a 2500 lumen projector. If you have a pretty big auditorium, I would recommend you start somewhere in the 4000-4500 lumen range. Obviously, it's going to cost a little more and I know that is a very important consideration. But if you go bright enough the first time, you won't be kicking yourself for it in a few months when you realize that you didn't go bright enough and now you have to buy another projector (NOTE: I'm speaking from personal experience on this. I was the Media Director for a growing church and we went through this exact scenario where we bought two 1100 lumen projectors which worked well for a short while showing PowerPoint. But as the church grew and as we started adding more video, the small projectors quickly became inadequate for the task and we had to upgrade to 4400 lumen projectors).
CONTRAST RATIO:
After
lumens, this is the next most important thing. Contrast in an image is what allows you to see all the subtle variations in color from black to white. Contrast is also what creates the illusion of depth in a two dimensional image. If you plan on showing video, whether it be I-Mag or film clips, the more contrast the better.
Contrast in the specs is shown as a ratio. You'll see something like, "Contrast Ratio- 4000:1." The ratio is a measurement of the difference between pixels that are fully illuminated (as bright as they get) and pixels that are essentially off or black. I read once that for a film to look good in a completely blacked out room, the projector needs to have a contrast ratio of at least 10,000:1. You're room isn't completely black, so ideally you would need more, but 10,000:1 is a good place to start.
BULB LIFE:
Bulb life is another important consideration for churches. Projector bulbs typically cost hundreds of dollars. Also, the brightness of some bulbs degrades or decreases on a curve over time. So, while the bulb may put out say, 1500
lumens when brand new, over time that output and the resulting brightness decreases. Eventually, you are forced to replace the bulb even though it technically hasn't burned out. So, long bulb life is a definite plus.
CONNECTIVITY:
Make sure the projector has the connection options you need to hook it up to your computer,
DVD player, cameras, etc (If you're planning future audio/video upgrades, try and think ahead about future connectivity needs). Almost all projectors have the basic connections you'll need. VGA connections for a computer. S-Video or Composite connections for video. But more and more, people need connections like
DVI for a computer or
HDMI for
HD. If you're not sure what I'm talking about, email me your questions or talk to the person you're buying the projector from.
RESOLUTION:
Resolution has to do with the number of pixels the projector can display. The more pixels, the smoother the image looks. You ideally want high resolution, but again, more resolution= more money. Proceed with caution on this one. Resolution is an area where creative marketing types spin out impressive sounding numbers that ultimately don't mean a whole lot. After a certain point, a difference in resolution is only
discernible to a select few (especially when an image is being projected in a large room).
OTHER CONSIDERATIONS:
There are still a few things to consider. Where are you going to put the projector? Is rear projection an option? How are you going to mount the projector? What kind of mounting hardware do you need? There are a wide range of solutions available and they will all depend on your specific needs and environment, which brings me to my final and maybe most important point:
Don't buy a projector until you've set it up and tested it in the area in which it will be used.
Testing out a projector shouldn't be a problem. If the vendor you're trying to get the projector from gives you a hard time about testing the projector at your church, find another vendor. This is a really significant and important purchase and you need to make sure the projector you buy is going to work for you.
There are a lot of highly qualified people out there who can help you make this important decision. When I was a Media Director and we upgraded our projectors, we went through a company called
Fowler Productions (Google: Fowler Video). They cater to churches and were very helpful in helping us find the right solution for us. Good luck!
