Making a good looking Halloween graveyard display is not all that difficult. All you need to do is follow a few simple rules:
Don’t over crowd your display: More isn’t always better when setting up your graveyard display.
Use small sources of light in front or around the tombstones: Candles (I prefer LED candles for safety), lanterns etc…
Don’t highlight all of your pieces with point lights: leave some in the shadows.
Bring in brush and leaves to cover the bases of things: this adds a huge amount to the display. I generally put the brush/vines towards the back of the display as a backdrop and the leaves everywhere else.
A lot of people have opinions about lighting so I will tell you how I have done it in the past. No one is right or wrong its all a matter of personal taste.
I use large par cans (par 64′s with 1000 watt bulbs) with very dark blue gels from the eves of my house washing the entire display. Then I use par 56′s down very low and side light the graveyard with very deep purple’s to make dark shadows on everything from one direction only. This creates a very dark moonlit atmosphere. All of my lighting is plugged into a DMX controller so I can turn down each light individually. A few props have amber spots or red spots on them, but not all of them, I leave some in the shadows. I don’t worry too much about people seeing the edges of the lights, they really don’t care, or even notice them. As long as you arent shining them in their faces there isnt too much to worry about.
Have fun after all it Halloween, most people won’t be in your display for more than 5 minutes. You will sweat the small stuff, they won’t.
