Do you aim to have some of the image just coming on the zebras? I'd imagine that would be a good thing also, so that you know you're using as much of the latitude as possible. If you were a stop out (i.e. There was nothing so bright that you could go a whole stop higher before clipping) then you're losing 1/2 the dynamic range which can't be a good thing either.

Well, I think that depends on the amount of light available. I'm
trying hard to remember my Lady X shoot, but it has been a while already. I think I only saw a couple of lines in some shoots. Mostyle I tend to shoot on the safe side. I'm more concerned with the overall brightness then getting the maximum highlight. I understand what you are saying. Trying to get the maximum exposure range possible, without crushing anything should give you more to work with. I just don't think I have mastered that kind of control yet. Especially since I'm also not using any lighting kit at this moment at all. So yes, I do think I'm losing a bit if the dynamic range. But I don't think it is half. Good question though! I'll play with that some more in the future.

Yeah I'm really interested now to start trying to control things a bit more. Going to look into a lighting setup soon I think. I'm already wanting to get into my next short film already!
Regarding dynamic range, I was just thinking of that post that Jeff did regarding it. Every stop that you go down you halve the light, and therefore, if you haven't got many highlights (i.e. you stopped down too far) then you lose half the dynamic range. For example. If I set up a scene so that I have some dark parts that are "as dark as you can go", and then I have some light parts that are "as light as you can go" and then I close down the iris one stop, the darks will crush, and highlights will now sit at the top of the second to last stop of the camera right? So I've effectivly lost a stop, which is 128 of the 256 possible light values - or half. Maybe I misunderstood his post. Anyway that's probably in extreme conditions and trying to manage that, as you say, could be a nightmare without controlled lighting. Catchya Aaron |

I read that as well Aaron and it's definitely important to maintain
as much as possible. But that's hard to do sometimes with our "limited" tools.
