GH3 ISO on GH series ?

[Vinyl Stax]

Hey Fam,

Quick question.
How do you guys go about rationalizing ISO values on the GH cams ?
Does setting higher ISO values protect the highlights in any way ? ( like on the RED for instance )

Anyone have some thoughts on this ?

thanks

I set it as low as it goes, raising as needed when there isn't enough light.

I generally tend to shoot at ISO 400, sometimes 800 when shooting live theatrical events. Anything beyond that is too noisy for me.

I don't know if there's a specific ISO that gives the GH3 greater dynamic range, but if there is I bet the difference is minimal. Much more important to me is the amount of digital noise in the image.

I've done some tests and I 'rate' the GH-1 @ ISO 100 with a ISO 250 setting on my Sekonic L-308DC incident meter. This yields a 50% IRE for an 18% grey card. That gives about 2-3 stops of 'higher values' before saturation.

Here's a 'red' discussion on the topic:
