Combine Images using Advanced Blending
So now we're going to take a look at ways to combine images that are really, really difficult to combine this is one of the images that we're going to create if you look at my layers panel you can see that the lightning is on one layer in a photo and are dancer is on another layer ok, so we've got two photos that were going to combine in interesting ways okay? So the other image that we're going to create is this if you look at my layers panel you'll see that both of those images live on separate layers and this has a black bag room can you even imagine how difficult it would be to select the black in that photo and mask it so that you can see through to this layer underneath? I don't even know if our blend mode tricks would work on that one ok, so that's what we've got going on in both of these images we've got an impossible selection or an impossible masking situation here there's no way you could mask this to make it look good okay, so how on earth did I lose the background of those...
two images in order to create this collage? Well, that's what we're going to look at next it's using something called blending sliders and they live in the layer style dialog box and you've probably seen them before but never known what the heck is going on with those sliders? Somebody go ahead and clues our lightning image actually closed both of these and I'm gonna open at the two original images that I've started with I stock matrix and I stopped hippie we're going to open these up and photo shop and now we need to combine those images into a single photo shop document so we can usar arrange documents icon at the top of the screen in the application bar choose the two a preview and now we can drag from one layers panel into the other open document or you could have selected all in one of the documents, copied it to your clipboard and gone over to the other document and, uh pasted six in one hand half dozen other ok, so we're going to drag our matrix photo layer into our hippie guy photo no, we can close the matrix because we don't need it anymore when activate the move tool and move the matrix photo over so it's about centered roughly within the document now what we want to do is open up the blending options for this particular layer and you can do that in a couple of different ways you can double click the layer itself or you can go down to the effects button at the bottom of the layers panel and she's blending options it doesn't matter which method you choose go and she's blending options and here we are in the layer style dialogue but usually when you're in the layer style dialogue you're looking at drop shadow options or stroke options okay someone turning these guys back off but if you click this allay area right here you will be seeing the blending options for the whole layer okay so the blending sliders are these guys down here at the bottom okay these two guys are you're blending sliders we're not going to be messing with this one right here we're going to be messing with the blending slider named this layer okay because we want to affect this layer the layer that we're currently on these little sliders let you tell photo shop what color you want to drop out ok so if I zoom back out if I start dragging the shadow slider over here to the right with what happens to the image black drops right out likewise if you want to drop out why if this image had a lot of white in it you would click this slider and start dragging it to the left and as I do that you see that white is slowly but surely disappearing from the image okay so here we are back at square one what I want to do is I want to click the shadow slider and drag it slightly to the right now the only problem is if I zoom into my image see how the edges are getting pixelated that's because there's no blending going on there okay those I'm dropping out black but I'm not dropping it out in a soft way I'm just getting rid of it okay? So there's a hard transition between what's left over and the image that you're seeing underneath well if you take a good look at this slider right here you'll see there's a little bit of white tick mark in the middle of it that is your one and only indication microscopic barely visible hardly noticeable indication that that slider can be split in half in order to soften the edges okay so I'm gonna hold down a modifier key and as I hold down the option key that slider splits apart this dragging it to the right dragging the right half of that slider to the right softens the area around what's left some now when we come back to our image we can see how those areas are softening up see they're not quite as jagged as they were okay, so what's really happening is that instead of continuing to drop out solid black by dragging that slider around I've split it into so it's really adding it's dropping out a little bit of gray as well so it's softening up the edges ok so that's happening by splitting those sliders apart and if I keep dragging that rightward slider over to the right now it's starting to drop out whatever color that it's underneath okay, so it makes it a little bit softer. So now if I zoom back out of my document and move the style log out of the way, I have exactly what I wanted it really is amazing so let's do that again I'm gonna cancel so all we've done at this point is we have combined to images into the same layer. Now we're going to open the blending options for one of the layers the layer that's on top and we can do that by either double clicking the layer thumbnail core clicking the effects button the bottom of the layers panel in choosing blending options same exact dialogue box opens either way go ahead and give it a click locate the blending slider down here in the bottom ok, the one that's marked this layer and if you need to drop out black then you're going to grab this slider and you're going to drag it to the right. Basically what this is saying is photoshopped please blend this image together bland if this slider is on this color okay, so it's blending everything to the left of the slider that color is being blended with the layer that son underneath it, but as you can see, I can keep dragging that, but the further I drag it, the more jagged the edges of what's left over in the image become and you can soften that if you split that slider apart so you're going to press and hold the option chiana, mac or all on the pc click the slider continuing you can even lift the button now when she split it apart by option or all clicking it you can release the modifier key and now this drag that half of the slider over and it's going to soften the transition so you don't have jagged edges left on the remaining bits of the image after you've blended it yes or you split how do you know how far to go? Great question how far you go before you split you've just gotta watch the zoom in and watch the edges of whatever is remaining in your image will very depending upon the colors that aaron your image so you just gotta watch him in same thing with how far do you drag the stew? The one half of the slider after you split it you've just gotta watch drag it until it looks good to you now again while yours aimed in it's that whole thing again don't drive yourself crazy trying to get it perfect you know zoom in take a look at what's going on get it looking pretty good the thin zoom back out and take a look at it at roughly the size of the image is going to end up being either when it's posted on the web or when it's printed and for this image it does an incredible job and there's simply no other way you could get that clean of a mask around all of those zeros and ones that are in there it would be impossible literally impossible so let's click ok so that's pretty amazing so let's take a pic get that on another image okay so this is what we're going to create this time if I double click this layer the lightning layer I can see the change on the blending sliders here okay, so this stays editable say this document is a psd open it up a year from now double click that some nail and you will still have access to those blending sliders to continue to find him it if it doesn't end up being exactly what you want in case we're gonna go ahead and close this one and start over it's a really open up I sought dancer and I stock lightning have you ever wondered how people are adding lightning that wasn't in the original image before? Do you ever wonder how the heck that was done? This is exactly how it was done hey, so this time let's go ahead and do our select all copy paste technique for combining the two images in the same document to showing you different ways to do the same thing so command a to select all comand see or control see the copy it to your clipboard go to the other document and then paste command viana mac or control v on a pc once you have images within the same document then we're going to double click the from nail of the one you want to effect to bring up the blending options or you can click the effects button at the bottom of the layers panel and choose blending options there doesn't matter which way you do it once that opens you're gonna locate the blending slider down here and if it's black that you want to drop out and it is we're going to move the slider to the right see how the black two starts disappearing but if I zoom in I've got really jagged edges going on on this lightning and I don't want that so to soften those edges you need to split that slider apart so option or ault click the slider to break it and then grabbed the right half of the slider and drag it to the right see how that edge is now softening up and how far do you drag these sliders around great great question from our in studio audience member here until it looks good to you this looks good to me so I'm gonna click ok now to make the image look riel we need to move the lightning around where israel is it can't possibly be when you know it's not really we're going to activate the move tool I'll zoom out a little bit and I'm gonna move my lightning over so it looks like it's striking right in front of his foot there not too shabby, huh? Go ahead if you have two images and like the second image you just want one little piece of it can you mask that image and then use this yes, absolutely. You can use this technique in conjunction with player masking absolutely now what if you have an image that has another color that you want to drop out isn't black ok basically just asked that in rio they're so good in fact people earlier were saying she's so good answering my questions before you can ask him so if you have a color that you want to drop out that's not black or white then you're going to use this poppet menu right here and you don't get very many choices but from red, green and blue spring every other color so by going through here in changing these and messing with their blending sliders you can get rid of any color you want okay, so the answer is you would change the blend if poppet menu to something else okay, I would much rather have this option say black or white really what it's saying blend okay you're asking me to blend something okay blend win blend if the color is gray scale which black or white falls within grayscale so that's why we have gray chosen there okay. If we were trying to drop out red or something in the red family then we would change this pop it many to red or green or blue hey, when you do that the sliders actually change colors too so that's how you can do that pretty darn amazing to have questions on that one and then we're going to go on to realistic photo aging oh yes, I know it's what you've all been waiting for a question from a redhead seventeen how would the screen blend mode work on the lightning? How were the screen blend mode work on the light now well, let's duplicate the layer. I'll turn this one off I'm gonna move my sliders back to bring back my original photo have to know the thing I love about this technique is it's so nondestructive, did you say that I just undid it? Okay, so now it's choose the screen mode. Actually, I think a lighter color would do a better job on screen so lighter color would work as well but way get a cleaner a cleaner edge by using the blending sliders because we've still got quite a bit of that background lord goring around so the blend moods may work it's all about options. You know one of these methods is gonna work better on the photo you're trying to fix or the art you're trying to create, then another one of the methods. My job is to arm you with the most practical, useful, nondestructive methods that I can think of. You're going to have to decide for yourself, which one of those is gonna work better on your particular photo, what's all about knowing your options in photo shop. One of these methods will work better than the other in as all y'all know, there are at least six ways in front of shop to do every single thing we've looked at it's, just that flexible one of those ways will resonate with you more than the other way.
