055 Gain without grain

- [Instructor] Hi, this is Steve Wright,…welcoming you to this week's Nuke Nugget,…how to increase the brightness of an image…with a gain operation without increasing the grain.…When you increase the gain on an image, it will, of course,…increase the grain right along with it.…In this week's Nuke Nugget,…we'll see how to fool Mother Nature and increase the gain,…without increasing the grain.…Can you say that ten times fast?…Okay, so we have a sad little 1K film scan here.…Let me push in on it.…

Very grainy, very noisy.…Let me jack up the viewer a little bit.…I'll make the grain pop for ya here.…Here we go.…Okay, so we got quite a bit of grain here…and the image is quite dark.…So I'm going to gain this thing up,…but I do not want to increase the grain.…So we'll start by selecting our image…and go to the Filter tab and grab a Denoise node.…There we go.…

Now, I'm going to have to move the sampler…up to a region that has no real texture in it.…So it'll sample the sky and oh what a lovely job…the Nuke Denoise node does.…
