So, through gritted teeth we acknowledge the limitations of this wonderful camera. One of the issues I had noted earlier on, was the problem of vertical banding/noise/lines. Whatever it is, it isn’t pleasant and I need to get to he bottom of the conditions that make it worse.
One of those conditions is making a film that involves a blind man’s darkened house. A lot of GHOSTGIRL’S scenes are in low light. Although it was a good test for the camera, we failed to spot the noise issue on the camera’s monitor or on our lovely Marshall monitor.
Of course when I checked out the day’s rushes and on our big plasma, I had a slight “Oh dear” moment.
Didn’t have time to get to the bottom of it then, but I am on the case. 1st point of call was to use only the recommended ISO’s from Philip Bloom’s blog on the Zacuto shootout – http://philipbloom.co.uk/2010/03/24/shootout/
I also played with the Highlight Tone Priority setting, as you can’t physically set ISO 160 whilst HTP is enabled(although apparently it shoots at a lower ISO than displayed in this mode and then compresses the picture to bring the exposure back up-I think…).
I thought I would use this HTP mode as the first test and I noticed the difference, especially when I bumped up the mid tones in FCP Colour Corrector.
I am going to shoot some more, and research a bit more. i may have missed a couple of articles online.
BTW apologies for the mis-captioning clip 2 should say Highlight Tone Priority DISABLED!
More tests to come…
