"Now to finish up the highlights on our rock planet. As we can see here, we have it, we have it embossed and it's really kind of messing it up because it's over the top of our nice beautiful layer here but what we're going to do, since everything is embossed, we're going to take our highlights and we're going to click on that, alt level. We're going to hit "Command L" and go straight into our input levels and what we're going to do is we're actually going to darken this down. Just bring it up like so, oops well we can't see it because it's let's hit cancel. Let's turn off the layer above it, there we go now his "Command L" and go into our levels and as you can see, we're going to adjust this to a point to where it's nothing but black with a little bit of white on it. Almost an alpha channel there we go, something like this, just going to take our white down and this back up like so. We're just going to keep adjusting it until we get what it is we're looking for like like so. That looks fine, we'll accept that, that looks good so it's not necessarily white squiggles but they're colored squiggles and that works for me on a black background so we'll accept that. We're going to go over to our shadows and we'll open it up. What we're going to do is basically the same thing but in reverse. We want to make sure that this is all black squiggles on a white background so let's take this down like so. Just bring it up a bit, bring it up into it like so, keep bringing it up. It's going to get hard-core before it gets any better; there we go something like that. We can also change our output levels down here too if we so feel like it. Let's bring our white down a little bit, no let's not bring our white down a little bit. All right, we're going to accept that too and we'll just hit o.k. on that. Now what we're going to do is actually, we're going to pause here and I will show you what these are going to do in a minute."
