Is there some standard method when using windows between spaces and the other side is supposed to look like exterior? I'm using either open face 1.2K HMIs or open face 575W HMIs. There are a couple of things I'm not so sure of.
1. Diffusion on the window, on a frame in front of the light or both? On the window, it would help hide the space behind the window. But the light fixture, if used without diffusion in front of it, would likely leave a hot spot on the window. I want to blow out the entire surface are of the windows. Also, if using too strong diffusion on the window, it would take out most of the directionality from the light. I want the light to have some directionality, like a hazy morning sun, not look like it's completely overcast. So I was thinking of placing some light diffusion on the windows to help hide the other space and some stronger in front of the lights with maybe some kind of honeycomb to give it more direction.
2. How do you make the light look like it's coming from above instead of sideways? Since the ceiling sets the limit to how high you can place lights, there's a problem with the light looking too horizontal and shining too much on the ceiling. Real daylight shines mostly on the floor even on an overcast day because the sky is a dome above us. So, I was thinking of using separate lights for skylight and direct sunlight. Would it work if I bounced the skylight from the ceiling right next to the window and placed a couple of fresnels close to the ceiling as direct sunlight?
