The closer your diffusion material is to the light, the more the light acts as a point source, instead of a diffused one. For example, there's no real point to using diffusion material in a gel frame, right in front of the light.
I don't understand the problem with the initial bid being too low for the amount of work finally done. If I hire a contractor to fix my kitchen, and halfway through I ask them to switch to better quality counters and cabinets, I know I'll be paying for that. Why wouldn't the same principle apply, if I'm not satisfied with my VFX and need more work done on them?
What is posted there is an abbreviation of what I wrote. I don't think there's a point to entering a discussion that's being handled that dishonestly.
I want to stop hearing about this film. You, the filmmaker, are too stupid to understand that you have made an entertainment out of the death of an animal. From your synopsis, the death of the animal isn't even the point, it's somebody's Daddy issues. It wouldn't matter if you had figured out how to eat the squeal, killing a pig to make your short narrative film doesn't benefit anyone. Stop making films. You are completely lacking in moral compass. No film with you involved will ever be anything but a completely worthless piece of crap.
