Without it you’ll have a tough time making sure that keystone is correct and the image seems flat to the projector screen or surface. When using this, you’ll be able to square up every corner, and make sure all your lines are straight. I always start with this, too make sure that the projector doesn’t warp, bend or angle in any way.

2. Broadcast Color Bars.

One of the first steps to getting great looking projection images, is to make sure that your colors match, and they represent the entire spectrum accurately. We can use this color bar pattern from TripleWide Media to accomplish this task with much greater ease. You can also see why this would come in handy for those doing edge blending or multiscreen, since the projectors would be so close to each other. Thus, these are essential blend grids for projection of any kind.
