Join Rob Garrott for an in-depth discussion in this video Gamma Control, part of NAB 2014 Panasonic's GH4 First Look.
We realized that with the GH3 there was a lot of, concerns about the gamma not being flat enough for people. They really want a flat gamma so they can cut it with other cameras, so that it grades nicer in post. So we've added product from our broadcast division, or functions from our broadcast division. We call it the cine-like profiles. Cine-like deals will give you a nice middle of the road, middle profile, which is going to be a nice wide dynamic range gamma.
By giving you that nice wide dynamic range gamma, you are now going to be able to grade this better in post and it's going to match up better with other cameras you may be shooting with. Or if you are just looking for a very professional look from the output, this will give you a very professional output look. Aside from having a cinema-like D gamma profile, we also have other functions to help match this camera to other products that you might use. So one of the challenges that we run into is that you know, Sony and Canon and Nikon and Panasonic. We all use slightly different references for black.
And so it becomes difficult for you to match this camera, to like a Sony or a, or a, you know, JVC on set. So we have something called Master Pedestal Function which allows you to lift that reference black point up or down so it gives you a better match to other cameras that you may be working with. In addition we also allow you to set your grayscale function. So historically photographers like zero to 255 for their gray scale. Zero being black and 255 being white. Well for video, in, in at least in the United States, seven is black and anything below seven is invisible.
The camera allows you set 16 to 255 gray scale. Or a 16 to 235, meaning that 16 is black and 235 is white. This gives you more latitude which you're less likely to lose beadwork in someone's dress, if you're shooting a wedding. Again a huge advantage to the camera.
