I don't want to pay money for shows I can't watch because they might kill me.įor context I'm a production manager with IOSH health and safety training and I also work as a lighting designer. It should be evident when I book my ticket. I hate hate hate when I go to see a show and I don't know there's strobe until I'm walking into the theatre and there's a piece of paper by the door. I'm also really sensitive to rapid colour changing but again, each person is unique. If the side or angled backlight is strobing I'm less likely to have a seizure than if it's front light or direct backlight. In my experience as a photosensitive person the angle from which the lights are flashing is really important. The recommended "safe" exposure to stroboscopic lighting in the UK is a burst of shorter than 3 seconds with a break before the next burst. Seizures can be triggered in people who are photosensitive by rapid changing colours and in some cases flashing lights which are slower than stroboscopic lighting depending on the angle the lighting is hitting the eye. But stroboscopic lighting us not the only thing that triggers photosensitive people to have seizures. Stroboscopic lighting occurs when there are more than 3 flashes of light on and off per second. Here's some things from my perspective (I'm from the UK so I'm not going to talk about American legislation but general courtesy and safety). (I've had people ask why we ban flash photography even if we've announced and use strobes in the show.) Flash photography is not only a distraction to other audience members, it can and will happen at the worst possible moments which could put a performer at serious risk of injury if they are blinded by or lose focus because of a photo flash. Something many people don't realize is even if we're using strobing lights in the show, we also purposely plan them so a) the performers know when and where they happen, and b) they specifically avoid parts of the show where performers could be in a dangerous situation needing their focus on not falling off the stage or a set piece. This same post and announcement usually also has the prohibition of video recording (if required by the production rights) and also flash photography. A fast moving light can be construed as a strobe from certain angles as well, and the two seconds it takes to mention it in our "welcome to." announcement doesn't hurt to have even if it isn't required. We haven't used a real xenon strobe light in years but it's not uncommon for us to use a strobing effect on our movers or the LED strips we use as stage wash. We reserve the right to remove posts and/or comments that contain blatantly dangerous advice.įor every show I've been involved in at the high school I volunteer at, I've posted at the doors and provided a (recorded) verbal announcement at the beginning of our shows for "moving and strobing light effects, and theatrical fog".
