Masks from Selections
One of the next things that we have are masks that we can make from a selection. So here is a good image to use for this. This is a portrait my wife took for me, specifically for this. You gotta set yourself up for success when you are teaching, right? So what we're going to do is we're going to use something called, there's a selection in here that is an intuitive selection so we've moved out of manual selections and now we're moving into more of the automated selections. They're a little bit more intuitive selections. One of them is called focus area and I'm going to show it to you because we need to look at this as a valid selection but it's also a very difficult selection to make perfect. So if we were to go to focus area, what this is going to do is this it's going to try and make a selection that is, that's on the area that is in focus. So right now the area that's in focus is going to be my head and my shirt and my hands and the background is then going to drop away and it's aut...
omatically going to make that selection for me for what's in focus. Now the problem here is that if you're working with something like a 1.8 lens on a portrait and you're right on the eye and there's a lot of bokeh and soft focus happening around that face, it might be more difficult for Photoshop to find that in focus range and if that's the case, you have an in focus range slider here that is going to help you find that area that you want to have selected. So if I move this in focus range up, anything that is in white is basically not going to be selected. Those are areas that it's just not going to select so if I were to press okay on this, I would look like I don't know maybe a robot or something. So what I'm going to do is just move this up a little bit and that actually, if I press control and space bar, I can move in. It's actually a pretty darn good selection. So usually that focus range can be difficult to work with if you don't have the very precise parameters of the lens that you are using. If you're using a 1.8 lens or a 2.8 lens or something that's got a lot of bokeh and soft focus to it, it can be difficult for this tool to find it. With this, I think it was at F4 so it's a really good focus to find that nice range between it. If we were to, what we can do here is we can select what we want this to output to. We can say do we want this to be it's own layer mask, do we want it to be a new layer, do we want it to just be a selection so that we can decide if we want that to be a new layer or do we want it to be a whole new document or a new document with a layer mask? So it's giving us a bunch of different options as to what we want to do. If I'm working with this image and maybe I wanted to replace that background with something else, I might say let's just make this a selection but there's also something down here called select and mask. And select and mask can also be one of those tools that's kind of difficult to use but when we pop over to select and mask, what it's going to do is it's going to give us what this would look like on whatever background we have set up here in the view mode and it gives me a bunch of different options as to what I want to do with this selection that I've created. We still have not created a selection yet. We made the focus area and now we're using select and mask with that focus area to make that selection a little bit better. So if I were to turn this to overlay, what we're seeing is that anything that's in red are areas that are gonna basically disappear, that I'm going to mask out and my selection is going to be anything that is not in red. Marching ants is going to be typical to what that selection would look like if we were to use any of the selection tools. Onion skin, this one allows you to see a little bit of the background through the selection that we're making and adjust the transparency so do I want that to be less transparent in the background or more transparent in the background. The onion skin is a pretty cool one to use. The other ones that are pretty helpful are black and white. This one will show you exactly what that mask is going to turn out to be once I make that selection. Anything in white will be the selected areas and anything in black will not be selected. So if I go ahead and change this to on layers, if there were a bunch of layers underneath this, when I pressed on layers, it will show me what this selection looks like with anything that is underneath of it.
