Practical Grain

[Freak]

Hi,

Can anyone point what should I do to create practical grain sequences?

I have access to a filmrecorder, 35mm cameras and a Telecine.

Thanks in advance

I got told in a shake class that a few of the guys
create a solid grey element and make some grain and match it to the footage required then save 4 frames of this to disk import it and loop it,

But if you want to i'd print out whats called a 10 step wedge.
attached below
stick it to a wall (neutral grey) and film it with your 35mm camera.
remembering the film stock , process your neg and put it through the film recorder and save it as your favorite uncompressed format for reference.

It would be nice to have all kinds of film stock available but that would be very expensive.

Hi Dreggsy,

I was thinking about doing a filmout of 10 frame sequences of solid 50% gray. I'm just not too sure about the color that I should use, if it should be pure black or a neutral gray. If I'm not mistaken the blend mode used to comp practical grain sequences is ADD due that I think pure black would do the work fine. With a 50% gray sequence I'm afraid that some color shifts may happen when things are comped toghether.

We have a laboratory where I work so I probably will have access for most of the film stocks avaliable, various Kodak types and Agfa stocks mostly.

The only problem is that for now I don't have access to film scanner so the sequences that I'm planing to do will be linear HD 1080p 4:4:4 scaned with a Spirit 2K with a Rave HD system from our facility.

Do you think I should filmout and then telecine your 10 step wedge with 10 frames (or less) of each one of the wedge's stages?
