Alrighty, welcome back. We're going to work on the file corwig_clean_up_04.jpg. Open up this file inside of Photoshop. F to go to Full Screen view mode, and then let's open up our Layers palette and zoom in a little bit more actually, Cmd + plus. Here we have this photograph of Lake Tahoe, and I was shooting with a wide angle lens, and I hadn't realized that I had recently dusted my lens, so you can see that there's all kinds of crazy dust showing up here. I need to clean up that up. So, double-click the Zoom tool to take it back to 100%. What I'm going to do here is use Smart Filters, this time I will right-click the layer, choose Convert to Smart Object. Next, go to my Filter menu, Noise > Dust and Scratches, and what I want to focus in on here is the noise that I was seeing in the sky.
And again, because this one is a low-res file, I'm going to see my numbers are going to be really low here, a Radius of two, Threshold of two. That looks actually pretty good. Let me just play around with this a little bit, see what's going to work best for us. Alright. Let's click OK. Now that we've done that, we see that the sky looks good, but we just lost some really important detail. So, click on the mask, fill that with black by pressing Cmd or Ctrl + I. Next, press B on the keyboard to grab your Brush tool. Get a real big brush, and I'll crank my Opacity up for this first bit of work, and I'm going to paint with white in the skyline area. And, this is going to do a couple things for me; One is it's helping me to remove all that dust that was up there, and two, it's going to help with these gradations that we're seeing in the sky. They're going to print a little bit better. This going on this way. I'm just going through and I'm reducing a few little items here that I think are a tad bit distracting. I am doing this by painting with white. If we want to see our mask, let's see if we're actually doing a good job, we can Option or Alt + click this mask icon, just like we can on any mask. In this case, it's showing me my sky was a little bit haphazard, so I'm going to go back up in there, and I'm going to clean it up. I love the shortcut because it reveals a lot. You can also Shift + Option, or Shift + Alt + click that to show you the mask and the red overlay. And, sometimes that's helpful to point out some areas that again, like over here, I wouldn't have noticed those areas had I not gone to this view. When you're trying to create a transition like from this area over here, I recommend you lower the Opacity a little bit. And, lower it some more, just kind of sneak in here a little bit so you're creating transition in between the areas where the noise reduction is needed most, and where it's not needed.
Now click on the eye icon, before and after. Excellent. We saved that image. Alright. That wraps up this one. See you in the next one.
