I have been experimenting with manual exposure on my HV20 and using the lock exposure method in Shutter Priority mode described here and in Barry's tutorial here:
My question is this: why does everyone feel so strongly you must keep the shutter speed at 1/48 when shooting 24p, and why is it such a bad thing if your shutter speed varies during shooting?
I know the obvious reason to shoot 24p at 1/48 is for improved low-light performance, and that this is the slowest speed you can shoot at using 24p. But it seems the pros here feel really strongly in locking the shutter at 1/48 when shooting, even in bright light, which in bright daylight would be overexposed without using an ND filter (external or the camera's). So why is it bad when shooting 24p and using manual exposure, in daylight, if your shutter speed goes up from 1/48?
And correct me if this is wrong, but the most the HV20's shutter can stop down to is F8, right? When the camera display says it's gone to F11, F16, etc., anything beyond F8, what it is really doing is keeping it closed down to F8 and applying the in-camera ND filter, yes? And coming from long ago 35mm SLR shooting this is probably another dumb question, but if this is the case, why can the HV20 not stop down to F11, 16, 32? Are all HDV camcorders like this?
