Hi, I wonder if there is any way to have Capture calculate the lux level on a surface? For some of our performances we have the requirement to reach a specific lux level and it would seem that rather than calculate this manually that Capture should be able to work this out based on fixture luminance, beam angle, focus, distance etc etc.
This would be useful for fixture/lens selection based on a minimum truss trim height where a specific lux level has to be achieved.
Does this already exist, or if not would it be considered for a feature request?
Thanks,
Ben
Hi,
I'm afraid this is not a feature we have currently planned to add. Calculating lux values needs taking global illumination (light bouncing around in the scene) into account and is very complicated and also often requires modelling the entire room (all walls, ceiling etc). It's tempting to think that's not necessary, but you'd be surprised what a difference that makes.
