Lightening and Darkening with Blend Modes

So why don't we continue on? And I've head first into a couple of more lightning and darkening techniques because these air also good techniques to have in your bag of tricks case all that options and photoshopped so the next image we're going to open up needs a little darkening. Okay, so I'm gonna go ahead and collapse my adjustments panel so we can see my layers panel and let's take a look at what's going on in our layers panel over here. I can see that there are two levels adjustment layers both of them have a similar mask. Ok, so let's find out what's going on on these layers if I toggle the visibility I off on this layer oh, I can see that there's a little bit of darkening that was happening in this area. So there's the before there's the after now, if I turned the visibility eye of this first levels adjustment off now I can see my original, admittedly overexposed image. Ok, so let me show you what I did here. I'm gonna go ahead and leave the visibility I off on those two layers t...

hat I created for you. You can also use for lack of a better term and empty adjustment layer to affect lighting in your image, it won't give you the color shift, but it will let you lightning or dark and areas very, very quickly. So what we're going to do is we're going to create a levels adjustment just like we did earlier, so choose the half black, half white circle at the bottom of your layers panel, then choose levels, and we're not actually going to make a change to the history. Graham so in other words, we just created levels adjustment, but because we're not going to change the level well, the brightness with the history graham, you can consider it an empty adjustment layer, okay? And the only reason we chose levels from that list if we're not going to really make a levels adjustment is is the first one in the list that doesn't make a change to your photo automatically just by opening it. Okay, so nothing has happened to our image thus far. We simply have a levels adjustment layer hanging out down here that we haven't yet done anything with, so I'm gonna go ahead and collapse my adjustments panel, and I'm gonna show you the trick to this technique, and you won't believe how well it works. If you need to quickly lighten your dark in your image, there is no faster way to do it than this non destructively, we're going to change the blend mode of this levels adjustment in which no change to levels has been made we're going to go up to the blend mode mini at the top of the layers panel if you need to darken the image, you're going to choose one of the moods in the darkened section. It just so happens that multiply works amazingly well for darkening your image when you choose multiply your whole image is going to get darker now we can use the included layer mass to hide that extra code of darkening, and you can think of it as a double code of ink it's kind of having multiply mode works it's almost like you took a piece of paper and you printed an image on it, and then you put the same piece of paper back into the printer and printed the image on it again, so it's almost like a double code of ink really handy and fast for darkening. There were no sliders to mess with. There were no anything to understand in a cryptic panel or dialogue box it's just a school flat darkening of your image. Now if the whole image doesn't need darkening, such as this example when we can go into the man asking, we can hide the darkening from the areas that don't need it arguably around the outside edges of the photo don't need to be darkened in his face doesn't need to be darkened so I can switch to the breast tool by pressing b set my foreground colored ship to black by pressing x because black is now the background chip I want to flip flop my color ships and now anywhere that I paint we're going to be hiding that extra darkening bring back a little bit of detail in the guitar strap in the guitar itself but this is a real down and dirty way too quickly darken an image now let's say that the image looks better than the original so let's take a peek of the before and the after but we still in a darkened some of the areas a little bit more like this area in his shirt we can simply duplicate this empty adjustment layer it's a commander control j to duplicate it and then maybe lower the opacity of that one okay so now there's arbor foreign after so it got a little bit darker on lee in the areas that need the darkening so that's a really fast down and dirty hand darkening technique and it's really efficient because if you remember when we had our layer discussion back on tuesday we we understood that there are no pixels going on in adjustment layers okay it's just really a set of instructions you're telling photo shop hey I want to make this adjustment so it says ok I'll take it out of that and it puts it on this layer right here an adjustment layer so it's a very efficient file size lies way too quickly darken an image and again we only picked levels from this menu because it's the first one in this list that doesn't automatic we introduce a change in your image we simply used the adjustment layer to get at its blend mode and to utilize the mask that automatically tags along with adjustment layer because the way this technique used to be done is people would duplicate the image layer then change the blend mode ok so we can do that so I can duplicate the layer now I can change the bloom modem multiply so they've got the same thing going on here but now I have to manually add a layer mask that's an extra step so and now I've got to image layers those air two layers filled with pixels that is going to increase the file size and it's not that I'm so worried about increasing file size it's just that you know techniques like this have been around for years and years nears with adjustment layers there's more efficient ways to perform these techniques now than there used to be so you're going to see me use empty adjustment layers for a couple of more things this afternoon for teeth whitening for I lightning anything that you want to quickly hand lightner darken this is the fastest, most efficient way to do it ok so let's take a look at the flip side of this technique on another image just as you can darken, you can lighten, so let's, take a look at this before image see how dark he is, then we can add an empty adjustment layer this time, the blend mode has been changed to something in the light and category because what's our goal to lighten part of the image. Okay, so you can experiment with the other modes in this category to do your lightning or dark, but I will tell you that screen works the best for lightning and multiply works the best for darkening just period so let's, go ahead and turn off this layer and let's do that again. Somebody go down to the half black, half white circle at the bottom of the layers panel choose levels again because it's the first one on the list that's not going to automatically introduce a change in my image. I'm going to immediately collapse my adjustment, palin, because I'm not actually going to make a change to the levels. Now, if I want to lighten this image, I'm going to choose the blend mode poppet menu and said it to screen it's gonna lighten the whole image in this situations that serves more the image that doesn't need lightning, then does it's going to be faster if I feel that mask with black to hide all of the lightning? And then I go back in with a white brush and reveal it only in the areas that I need tio, which is really only his face and I'll tell you there is an argument here that we should just let his face remain dark I get that so I already have black is my four grown color chip in my tools panel so I can use our keyboard shortcut of option delete on a mac or all back space on the pc to fill that mass with black they're by hiding that lightning from all of the image now I can come back with my brush tool set to paint with white black conceals fight reveals so my brushes already active in my tools panel I need to set my color ships to the default of black and white because I don't have white assessable right now someone oppressed d why it is already on top so now I can come over to the parts of the image that actually need to be lightened and I can quickly hand paint across those areas very, very fast est no frills down and dirty hand darkening and lightning non destructively with an automatic layer mask in the very efficient method that's not going to add a bunch of fat to your file size now if this lightning was a little bit overdone, what do we do? Drop layer opacity ok, so if here's our before here's our after in the adjustment layer lightened our image a little too much mask off the areas that didn't need it and then dropped the opacity of the whole layer to make the change a little bit more subtle, infinitely flexible stuff here and again, if let's go ahead and raise the opacity back up two hundred percent if this image needed even more lightning duplicate that adjustment layer and then if you need to drop the opacity of the second adjustment layer very, very flexible, easy to understand technique very efficient so let's do it again on one more image actually this image we're going to do both were going dark and enlighten ok, so let's take a look at our before so let's look at our our layers panel and see what's going on here okay, so we've got one adjustment layer and then we've got another one actually these are set tio multiply and screen, but anyway, we'll recreate them okay, so here's our original image I need both darkening and lightning in this image. This balloon in the forefront is too dark and my background is too light, so I'm going to create another levels adjustment layer immediately closed that panel and we're going to set this one to screen and that's gonna lighten everything now I'm going to go in with the regular paintbrush set to paint with black zoom in a little bit so we could see the whole image now I'm gonna paint toe hide the darkening from the background and here again if you started out with a selection if you can get a selection of this background area before you create that adjustment layer and photo shop would feel in the mask for you okay, so now I've got my darkening hidden from the areas that don't need it now let's take a look at the before and after case our balloon is lighter okay some now it's create another adjustment layer she's levels again closed that pain because we're not really going to make a levels adjustment this time was changed the blame mode to multiply and because our balloon didn't need to be darkened because we dislike end it we can paint with black toe high the darkening from the blue so now evened up with is an image that looks a lot better ok so here's the before and after of the darkening it darkens at background right up and if it's a little too strong back off capacity and then here's our lightning layer because the balloon was a little too dark in the original shot and we lighten it up if it's a little too light back off the opacity until it looks good to you so that's a really key quick way to change just the lighting in your image, without having to worry about missing with color. Because we're just lightning or darkening. And we're doing it, doing it in a very efficient manner with empty adjustment layers.
