My old camera I used for taking pictures of my haunt is about dead. I'd love to know what you use, and please show examples!
Then you are going to need a tripod and play with a longer exposure and try to not blowout the lights while using those lights to expose the scene so you get some of that too. An advanced trick is to use software, or a mode in many cameras called HDR for "high dynamic range" It takes multiple shots at different exposures and combines them. Some scenes are impossible to shoot without this if the difference between light and dark is too great and you want detail in both.I need to shoot in the dark to really get the lighting.
