Cine Gamma

hEY,

I was just wondering if someone could explain to me the function of the Cine Gammas as well as in what situations I want to use which one. I made another post and was told to read adam wilts website (the part on cinne gamma's). I got more confused by reading it. I either did not understand or the answer to my questions was not there. Hence, could someone help me out by answering my questions?

Thanks,
Yue
 
Re: Cine Gamma

ill try to say this as simply as possible. the different gamma settings refer to the way the camera records colors. a gamma curve is a measurement used in the good ole days of 35 film to give a visual representation of how different film stocks worked in various lighting conditions. i.e. some some stocks are good for outdoors at high noon and others are good for indoor in daytime and some are good for night, inside or out. the curve would show which film type to use. since video sees colors in a different way than film, its gamma curve is different and is one of the key elements that makes video look like 'video'. the cine gamma settings on the dvx are supposed to make the colors look more like the range of colors a film camera would record as opposed to a video camera. as to which one to use...thats personal taste. experiment :)
 
Re: Cine Gamma

The final goal with filming (photo,film,video...) is to reproduce exactly the amount of light and color that each element in a scene represents. This scene/image (gamma) relation is not allways perfect. Film material has a specific relation which (among other things) tends to make the mid-grays somewhat darker than they are in the real scene. This specific "distortion" contributes to "film look" when it is being applied to video.
 
Re: Cine Gamma

right !

but the problem is that video cameras lack the dynamic range of film, and with the correct gamma setting, you have even more dynamic range limitations, unless you use perfect lighting, which is impossible outdoors.

maybe a special (Tiffen' Shneider... or other brand) filter would help.
 
Re: Cine Gamma

Indeed, dynamic range is also one of the many things which limit the "film look" experience. Also the visualisation (projection) approaches play their limiting role.
