Photoshop CC One-on-One is back, and this installment teaches you how to build on your basic knowledge and achieve next-level effects with this premiere image-editing program. Industry pro Deke McClelland shows you how to seamlessly move and patch areas of a photo with the Content-Aware toolset; stretch the brightness of a scene with automatic and custom Levels adjustments; create intricate designs with text and shapes; and morph an image with layer effects and transformations. Deke also shares his techniques for sharpening details, whether addressing noise and highlight/shadow clipping or camera shake, and converting a full-color image to black and white. The final chapters show you how to best print and save images for the web, making sure all your hard work pays off in the final output.
In this movie, I'll show you how to adjust the Blend settings associated with the Smart Sharpen effect for two reasons. First of all we want to limit our sharpening to just the luminance information. Because if you end up also sharpening color as happens by default, then you can end up with all sorts of color artifacts. And secondly, we want to avoid clipping of highlights and shadows along the sharpened edges. So, the first thing I'm going to do here is double click on the Smart Sharpen filter to open up the dialogue box here.
And I'm going to zoom on in, which should help to wake up the preview as well. And now I'm going to crank that amount value up to 500% and I'm going to take the radius value up to 5 pixels, like so. So, that we're seeing a massive amount of sharpening. And notice that we're sharpening not just the luminance info but the color as well. And you can see that by clicking and holding. So, when I click and hold inside the image, I've got green behind the butterfly's back and I've got blackness inside the butterfly.
I've got a little bit of blue inside the insect's eye as well as his proboscis, or whatever that thing is. But as soon as I release, so I can preview the sharpening once more, all of a sudden we've got tons of colors leaping out of nowhere. There's all these purples and blues insides its fur and there's just a ton of color action inside his eye and this curly thing over here. Also notice these pink patches. Before they were pretty muted and now they are over the top. What's happening here is that Photoshop is sharpening the image on a channel by channel basis.
So, we have an RGB image, which means that Photoshop is first sharpening the red channel, then the green channel and then the blue channel independently of each other. And that's the way just about everything Photoshop works incidentally. And as a result Photoshop is exaggerating the discrepancies between the various channels and so these bright colors are being brought to life. The solution is to go ahead and accept your changes by clicking on the OK button. And then notice this pair of sliders to the right of the words Smart Sharpen. That indicates the blend settings.
If you double click on those sliders you'll bring up the Blending Options dialogue box, which allows you to adjust the blend mode and the opacity of the effect. So, the first thing you want to do and you want to do this every single time you sharpen an image is change the mode from Normal to Lumenosity. And that way, you're sharpening the luminis info and you're avoiding the the color info. And notice what a big huge difference that made here inside the image window. So, I'll show it again by turning off the Preview check box.
Keep your eyes on the butterfly here this is the before version of the photograph with all those color artifacts coming to life. And when I turn the Preview check box on, this is the after version where we're sharpening just the luminates. Now, the other thing you want to do is reduce the opacity value. Let's say, because I took the radius value all the way up to 5 pixels that the ideal amount value would be 300% as opposed to 500%, which I've applied here. 300 divided by 500 is 3 5ths, which is the same as 60%.
So, we'll get a pretty similar effect with 300% amount value by reducing the opacity value to 60%. But there's an important distinction. I'll go ahead and click the OK button to accept that change and then I'm going to copy this layer by pressing Ctrl+J or Cmd+J on the Mac. And I'm going to reset this guy's opacity by double-clicking on that Slider icon and I'll take the opacity back up to 100%. But I'll leave the mode set to luminosity. You'll always want to do that and then I'll double click on Smart Sharpen, go ahead and zoom in so we can better see what's going on.
And I'll take the amount value down to 300%. And then I'll click OK. So on this top layer we've got a combination of 300%. I'll go ahead and enter it, along with 100% opacity whereas this guy right here is set to an amount of 500% combine with the 60% capacity. And now, I'll go ahead and zoom in one more click here. And what I want you to notice is that we do have a little bit of clipping along this edge.
So, we are getting some pretty hot highlights on the right side of the edge and some very black shadow detail there on the dark side of the edge. If you want to avoid that kind of clipping. Then you're better off, instead of going with the proper amount value combined with an opacity of 100%. You're better off going with an elevated amount value combined with a lower opacity value. And let me show you why. I'll go ahead and turn off the genuine 300% amount and you'll see that that edge clipping goes away where the 500% combined with 60% opacity is concerned.
And yet you end up getting a very similar effect. So, I'll go ahead and zoom out to 100% here. And I'll turn on the genuine sharpening effect complete with a little bit of edge clipping compared to the elevated amount value combined with the reduced opacity value. Which produces a very similar effect without the clipping. So, the rule of thumb is this. You always want to change the blend mode for Smart Sharpen to Luminosity. What we've seen here is an exaggerated scenario but even if you don't see it, it's happening in the background and it might prove to be a problem in the future.
And if you are concerned about the edge clipping, then you can take advantage of this trick where you increase the Amount value and reduce the opacity setting. And that's how you adjust the blend settings associated with the smart sharpen effect here inside Photoshop.
