hmc 150 Scenefile handbook updated

Thanks for that.

By the way, I noticed a strange passage on page 9 regarding Cinelike D (also the same with Cinelike V).

It says to adjust "the iris to reduce the video level to approximately 1/2 of normal video level".

I presume it is talking about exposure? Why would you want to reduce this by 1/2, wouldn't it all look too dark? Anybody got any idea why they would say that?

Much appreciated.
 
I believe its for filmouts and grading. But I could be wrong.
Also A IRIS level is not explained .
So basically I still have to order Mister Green's book .
 
What they're saying there is that you want to make sure not to overexpose. Cut your exposure by a half a stop to a full stop, because there's no rolloff in the highlights when using the CINE gammas. It's a linear slope, so when things blow out they blow out suddenly and ugly. So you want to make sure that you don't let anything blow out; that's why they're suggesting to lower the exposure.

I say don't sweat that, instead put the zebras on 105 and make sure you never see zebras and you'll be fine.
 
Thanks Barry. That's useful to know. Most of my work is weddings with conditions varying from bright summer sun to very dark churches and discos. Is there a scene file that you would recommend for this. I have just been using F1 Normal so far as this is my first camera with this level of customisability, and I'm wary of screwing it up! Can't wait for your HMC Book BTW.

Thanks,

Stuart
 
One thing that can help (and hurt) in a wedding scenario is the DRS function. Weddings really stretch the camera's capability to handle the dynamic range, because you usually have black tuxedoes and white wedding dresses in the same shot; add some sunlight in there and yeah, you've got trouble. The DRS function, especially on "2" or "3", can really help there, but at the expense of making the scene quite a bit grainier and noisier. There's no free lunch, after all.

Some tricks to try might be to have the bride stand in shade and the groom in the sun, etc. Or try to keep the sky out of the groom shots, etc. You can't always arrange for stuff like that, but when you can it might make things easier. Of course, when you have a very dark-skinned bride in a bright white dress, you're just going to have a challenging situation no matter what.

Typically I'd say use Cine-D for this, with the zebras at 105 and not letting any zebras show. But you should experiment with DRS and see if you like what it does. DRS is kind of like using gain but only where you need it; it intelligently analyzes the picture and gains up the areas that are too dark, and yanks down areas that are too bright. It only works in 60i or 60p mode, but that's probably what I'd be shooting a wedding in anyway.
