WEBVTT 99:59:59.999 --> 99:59:59.999 PROF VAUGHN: Okay, and this video is at using a gradient as a transparency mask. 99:59:59.999 --> 99:59:59.999 So we think of layer masks as revealing or concealing using black or white paint, 99:59:59.999 --> 99:59:59.999 and a range of grays. 99:59:59.999 --> 99:59:59.999 We can use a gradient that is set from black to white to create a really subtle 99:59:59.999 --> 99:59:59.999 blend inside of a layer mask. 99:59:59.999 --> 99:59:59.999 This gives you a lot of blending opportunity. 99:59:59.999 --> 99:59:59.999 So let's do a really obvious example first, I have a colour photograph open, 99:59:59.999 --> 99:59:59.999 I'm just gonna do a layer adjustment, adjustment layer, I'll do it black and 99:59:59.999 --> 99:59:59.999 white so you can have a quick view of how this might work. 99:59:59.999 --> 99:59:59.999 So of course we know our adjustment layers come with gradients. 99:59:59.999 --> 99:59:59.999 This is the effect, this is the- I'm sorry, they come with a layer mask. 99:59:59.999 --> 99:59:59.999 That is the layer mask. 99:59:59.999 --> 99:59:59.999 So if we wanted to use a gradient to blend in the layer mask as a method of 99:59:59.999 --> 99:59:59.999 transparency blending, you could still use that gradient tool. 99:59:59.999 --> 99:59:59.999 When you look at your gradients, you're gonna pick the black and white 99:59:59.999 --> 99:59:59.999 version here. 99:59:59.999 --> 99:59:59.999 So this is black and white. 99:59:59.999 --> 99:59:59.999 Whether or not you reverse it is up to you, remember the way a gradient in a mask 99:59:59.999 --> 99:59:59.999 with black and white will work; black is going to reveal, 99:59:59.999 --> 99:59:59.999 white is going to conceal. 99:59:59.999 --> 99:59:59.999 So, let's just do, um, let's do a radial gradient to see what this might look like. 99:59:59.999 --> 99:59:59.999 I'm gonna click and drag, now remember I've made sure I'm on the layer 99:59:59.999 --> 99:59:59.999 mask thumbnail. 99:59:59.999 --> 99:59:59.999 So this is isolated, it's a pretty small gradient, let's make it a little bit bigger. 99:59:59.999 --> 99:59:59.999 And it's pretty soft, but you can see I've got black and white now here in the middle 99:59:59.999 --> 99:59:59.999 radiating out in my layer mask. 99:59:59.999 --> 99:59:59.999 If you wanted to do a really weird, kind of, small spot, you could. 99:59:59.999 --> 99:59:59.999 Let's look at a linear gradient, now I've sort of moved from black and white, 99:59:59.999 --> 99:59:59.999 shifted it slowly into colour, because again the black and white in the layer mask is 99:59:59.999 --> 99:59:59.999 revealing of concealing, so the white in this case is showing what's underneath. 99:59:59.999 --> 99:59:59.999 So that is a a adjustment layer. 99:59:59.999 --> 99:59:59.999 If we were thinking about using these, um, to perhaps make some actual editing 99:59:59.999 --> 99:59:59.999 adjustments, we could think about not using them for creative purpose, but for 99:59:59.999 --> 99:59:59.999 perhaps fixing an exposure issue. 99:59:59.999 --> 99:59:59.999 So in this particular image, the land is well exposed, it has good contrast, but 99:59:59.999 --> 99:59:59.999 the sky, because the sun is probably over here somewhere, is a little too bright. 99:59:59.999 --> 99:59:59.999 It's a little bit blown out, we're losing out
