  1. I've noticed that ARRI lists the safe distance for their ARRI 300W tungsten as 1-2 meters. Does that mean it's dangerous to be close to the ARRI even if it's facing away? How hot is it within a meter of it?

     

    If it's too close to a wall or curtain or makes contact could that ignite a fire?

     

    Also are two arri 300W enough to light a small room?

  2. So, from what I understand the best quality for indoor film is Kodak 200T, at a smaller aperture like F/6 or F/8.


    But what I don't understand is which ARRI Tungsten lights do I have to buy so that will be bright enough at 3200k and 24 flood light level. Let's say I have 2 of them. One for the foreground and one for backlight. Does that change the calculation?


    What if there's some outdoor light coming in through the curtains? I know T Film isn't designed for that kind of light so should I try to block out all light coming into the house?


    I don't understand how to calculate how to get the 200 ISO with the aperture and shutter speed.

    I know the shutter speed is naturally at 130 Degrees (giving 1/65 sec at 24 fps).


    Does that mean for 200 ISO. I would need an EV around 8.0, 1/65 and aperture of F/2.8?


    And for 200 ISO. I would need an EV around 9.0, for 1/64 and an aperture of F/6.3?


    But what's also confusing about the Bolex is that there are the RX lens and the regular lens. Are RX lens better? Does using them mean I don't have to calculate the 25% that is lost?


    Please help me understand this
