adding more lights to show off your specific detail does not mean the set has to be too bright! dim those sob's...if i'm correct, i believe the darkness is using a lot of led mini spots to light the sets (as i'm told by others, i have not seen for myself)...dim your fixtures, it sounds like work...but if each fixture in a scene is individualy dimmable you can contol whats highlighted more than everything else in the room.
something tells me lately, that the next hauntworld dvd could have huge how to's on lighting your haunt "the right way" haha.
dimming is definitely one solution, but it adds time and money to the equation.
on a future model of our lights, we may consider building in a dimmer... we'll have to see if the costs added are what customers are willing to pay for the extra feature.
