Refine Edges Part 1
Let's take a peek at using the refined edge dialogue ok so this is the next thing we're gonna create right here so this girl right here that is dancing around on a fun happy disco background if we take a peek in our layers paint all you're going to see that she did not used to live on that disco for she actually was on a black back room okay, so we could use channels for this but it's all about options so we're going to take a look at yet another way the newest way to create really tough selections and that is by using the refined edge dialog box okay, so I'm going to go ahead and open up my dancing girl actually I'll open it both those images I stopped disco floor in the eye scott advancing girl so using channels to create tough selections has been the only way to get these tough selections for years aside from buying a third party plug in specifically for selecting crispy stuffed like karen for channels was the end of the line for a while there up until version cs four we had a filte...
r called the extract filter and that was also helpful for creating tough selections like this but with cs for adobe did away with that filter and now we have the refined edge dialog box which is arguably more powerful than anything we've had before for tough selections more powerful than channels it's all about knowing all of your options so one of them is going to work better on an image than another and there's no way to really know that unless you get into it okay, so what we're going to start out with here is we've seen the refinish dialogue before when we were fixing the animal white I so what we want to do is we want to start with a selection, okay? So what's the easiest way to get a selection of what we have here? Well, one of the easy ways is to use the quick selection tool and we're simply get a click and drag to paint the selection onto our girl and this is a good exercise in using this tool, you could select the black and then flip flop this election, but I'll go ahead and do it this way. I'll zoom in a little bit now remember when you're using this tool the size of the area that photoshopped grabs as a selection is proportionate to the size of the brush cursor, so if I want to select her arm I want to go down and brush size and I'm gonna paint across her arm and photoshopped did include this area in the crook of your arm I can delete that from the selection by putting the tool in subtract from selection mode by holding down the option or the all key on the pc and then just painting back over that area now I need to come down here and grab the other arm I've still got my really small brush tool so did a good job of selecting that area so basically you just want to start out with a rough selection and then we're going to use the refine edge dialogue to perfect it remember if you don't see the refine edge button in the options bar then either you don't have an active selection or marching answer on your screen or you don't have a selection toll active so you need those two things to be happening in order to see this button so we're going to go ahead and click the refined edge button and because we use this dialogue earlier and we set it tio the red overlay previ mode that's what you're seeing on the image so don't let it freak you out that it turned red the red is indicating the selected area I'll go ahead and zoom into my image a little bit more here so all of your resume in space bar tricks from moving around in the image still work even though you have this dialogue open the new thing and c s five is this smart radius okay, so this whole edge detection section does not live in cs four this is cs five on ly arguably worth the upgrade price this one button right here so what this is all about is that this smart radius edge detection section is your way of saying, hey, photo shop, yeah, I'm dealing with fern hair here, so if you would take another look at the areas, I'm about to point out to you, and if you would try to find two in your selection to get the wispy parts that's what you're asking it to do with this smart radius so your first step is to turn it on your next step is to tell it how far out from your rough selection do you want it to analyze? If you're dealing with wispy stuff, then you want to drag it up to at least around ten or so. This is pure experimentation. There are no magic members for this slider, it's going to vary on a per image basis, you just have to experiment with it. So I'm going to go ahead because I have done this one quite a few times and pump this up to about twelve, so basically I'm saying, yeah, look outside of my original selection about twelve and a half pixels and see if you can find anything else that you think needs to be selected, okay, since I'm using the red overlay it's very easy for me to see what is in my selection wasn't. And what isn't yet in my selection, anything that's red is included in the selection. Anything that is not read is not included in this election. Now I have to tell photo shop if you would if you don't mind, please take an even closer look at these areas I'm about to paint over, so when she turned on smart radius and you've pumped up the radius to an amount, you really can't be more specific the man. Now you're going to grab this little tool right here, it's a poppet mia needs got two tools hidden in it, so I'm going to click and hold down my mouse button, and I see that I have two tools. I have a refined radius tool, and I haven't erase refinements tool again could not be more cryptically named. We're going to use the refined radius tool to paint over the areas that need to be included in the selection, so we're going to use that told a paint over the wisps of hair that aren't yet read. If we happen to paint over something and photo shop includes it in selection and we don't want to include it in selection, then you can use this tool, tio delete it from the selection, ok, so you're going to be using this one the most the time, so let's, go ahead and click refined radius I was in back out now we're going to come over to my image and we're going to paint over all the areas that we want included and as soon as I released my mouse button, watch how that changes I'm even clicking and dragging in the hair because there are bits of the background in there and as I'm painting over that area photo shop is going to take a closer look at it lots of people shaking their heads in disbelief in the studio audience so that's your job is to keep clicking and dragging over all the wisps anything that you want photoshopped to take a closer look at and this is when that space bar trick really comes in handy for moving around within a zoomed in image okay, I'm even going to come down here in this area and I'm gonna paint back over that area and see a photo shop can take a closer look at that to zoom out a little bit, come down here a little bit bigger brush with my keyword shortcuts can you even believe what you're saying and remember anything that's red is going to be included in the selection some of the keep moving over now I'm working on the right hand side over here here we gov ok so let's call that good now what we can do is if you think your edges might not be smooth you can increase this slider if you wanted a feather dish for some reason you could increase that slider if you're unable to make photo shop grabbed the things that you want, including the selection you can tell it tio hey really increase the contrast of that selection is so look for areas of more contrast and the same thing with the shift edge like we use on the animal wide eye, you can increase the size of your selection or decrease it down under output decontaminate colors will try to get rid of any of loitering black pixels and last but not least before we take a much needed break, we're going to tell a photo shop what we would like to do with our new selection and you have a pop it many that says I can send it to a new layer I consented to a new layer with a mask I consented to a new document or a new document with a mask, so I'm gonna go ahead and choose new layer with mask and click ok and you're done now I still have a little bit of a problem here, but when we come back from break we're going to do it again and we're going to take a look at a few other options that we can use to try to get rid of the risk that black and then put it on our fancy disco background
