Increasing the grain by adding noise

The next thing that we'll be adding to our project is some noise.…And what I want to do,…is I want to add noise to everything that we've done so far.…And if you're working with a layered workflow like we're doing here,…where we have the original, the blur, then the texture we added with fibers.…What we need to do is to merge everything to the very tippy top of our layer stack.…To do that, you can use a shortcut it's Shift+Opt+Cmd+E on a Mac or…Shift+Alt+Ctrl+E on Windows.…And now that we've merged everything we've done up here, we'll go ahead and…double click this layer name we're going to call this one noise.…
