I was looking at the thread about that yesterday, I watched the trailer and it looked AMAZING!!! I was surprised that a camera almost as old as me could be used to shoot scenes that looked that good. I still have a lot of learning to do, but I hope that I'll be able to get good enough to make something even remotely as good as that.
If you follow a basic protocol for each shot, you'll do well with it. I always set the ISO first. For that film with that lens, outdoors was ISO 200 and indoors was ISO 800. Scenes in a parking garage were treated as indoors most of the time. So set your ISO first, this is like choosing a film speed (ASA) in the old days.
Next, f-stop. With indoor dialogue scenes, try to keep that number as low as possible. On our kit lens, this varied between 3.5 - 5.6. For outdoors action, we would use a higher number like 19 if we didn't have an ND filter that day. Basically, if you don't have ND, your f-stop will be your main method of adjusting exposure.
Third, white balance. This is crucial on these cameras since you can't really fix a bad white balance in post with these 8bit files. Without Magic Lantern, you'll light your scene, set the exposure like I mentioned above, and hold up a piece of white paper (we used the back of the script). Take a still photo off it, then you'll go into the camera's menu and load that image to set the white balance. If you have Magic Lantern (highly recommend that you do), you can dial it in to perfection. Outside will be 5200-5600 and inside will be between 3200 and 4000 if you don't have daylight balanced lights.
In summary: Set the ISO based on inside vs outside, use ND and set the f-stop for correct exposure, then white balance the shot. Don't mess with the shutter speed. Leave that at 1/50 if you're shooting 23.976 fps
