The blending modes uh will allow you to blend the pixels in the layer that you have selected with the pixels of the layers underneath them and you can create all kinds of amazing effects that way. So what I'm going to do is I'm going to close these guys here so we can just focus on this drop down list, the blend modes themselves. First if all we have normal, normal does absolutely nothing, it leaves the pixel information as it was when you first opened the image. Now I'm gonna show you the other one, this is dissolve, now dissolve will add a dithering effect to the pixels but it's most easily seen if the image is blurred in some way. So I'm gonna turn it on first and you'll notice a little bit of dithering or dissolve going on, on the edges. So we're gonna undo that, this time I'm gonna add a gaussian blur and I will reapply the blend mode called dissolve and you can see a much harsher dithering here because the image has been blurred. So let me undo that and step backwards and head on down to the next blend mode. We have darken, now the way darken works is if the pixels in the image of the currently selected layer are darker than the pixels in the layers underneath it the pixel retains its visibility. Likewise if a pixel is lighter then the pixels visibility is turned off. Now we have multiply, and multiply is very, very popular for comic book artists because if you have line art that has white and black in it multiply mode will keep the black line art and hide the white and a lot of artists use this. So what you would do is on this layer you have your multiplied artwork and you would start your coloring on the layer underneath it because even though your coloring on the layer underneath it the white has been knocked out so you can still see the line art clearly and it's a very popular way to color. And what multiply really does is it darkens pixels and it creates dark shadows. It's very, very handy. Let's talk about color burn. Now color burn is like pretty much dipping the image in lava, it really gives you a nice bunch of saturation in the image. Linear burn is like taking that image and just leaving it out in the sun for a long time to get some really, really dark burns and very dark shadows. We also have a mode called darker color. This is new to Photoshop CS3. What the darker color will do is take into account the channel values for the blend and base colors and then display a lower value color. Now I also just want to jump over here very quickly to show you the opposite which is a lighter color and lighter color takes into account the channel values for the blend modes and, and the base colors to display a lighter color. So I just want to talk about those two very quickly and jump back to the next section here. So these are our darken modes and this section now we're going into are our lighten modes. Alright so let's talk about lighten now, now lighten works in exactly the opposite direction of darken. When you apply lighten the pixels that are lighter than the pixels on the layer beneath it are the ones that you see. If the pixels are darker then you don't see them. Alright let's go ahead to our next section which is screen. Now screen mode will mix the pixels on an image on one layer to lighten the pixels on another as you see here. Now we have color dodge the king of saturation, it really brightens the pixels and gives you extremely, extremely bright, hot colors that'll give you a very nice saturated feel. We also have something here called linear dodge add and what this will do is it will brighten the base color of each channel to increase the brightness and we talked about lighter color already. Now over here we have some contrast modes here and we'll start off with overlay and then I'm going to then go into another lesson to talk about the rest of them. So let's go ahead and just start with overlay very quickly. Now what overlay mode will do is take a look at the pixels that are in the middle regions between the lightest and the darkest in your image and then let you see through them. Alright so we've taken a look at some of the blend modes and we're gonna continue talking about the rest of them in the next lesson but the best way that I find to learn how to use these is to literally overlap two images and kind of just pay attention to what's happening because after a while you're gonna find special effects that you like the most that you're gonna re, require for certain images like b, based on your art style. And me personally I use multiply quite a bit, I use screen a lot and I use overlay. The rest of them I don't use to much unless I really want to saturate it and then I'll go ahead and choose something like color dodge. So once again just take some time, experiment and really get to know how to use these blend modes. They're very powerful and they're very helpful in your artwork.
