AI-assisted (Neural) Filters

“

- [Instructor] Photoshop has several experimental filters intended for creative photo editing scenarios. These filters use artificial intelligence and machine learning to create completely new pixels to fill in content in an image. Let's take a look at a few examples. I'm going to start with this gray scale image. Well, actually it's not gray scale, it just appears to be gray scale, but we can see it is in RGB. If you're working with a gray scale image and you want to add color to it, you'll need to select the image menu, come down to mode, and change it from gray scale to RGB color. Now, to add the Neural Filters in a flexible manner, I'll choose filter and then convert for smart filters. Then I'll choose filter again and select the Neural Filters. Now, the first time that you run some of these filters, there will be a cloud icon or a download button, which you'll need to select to download the AI model from the cloud. In fact, some of these filters, like the smart portrait filter, need access to the cloud to do the highly intensive processing that's required to create the new pixel information. Now, the list that you're viewing might be different from mine as Adobe will most likely update and create new filters over time. Let's start with the photo restoration, we can see it is a beta filter. I'll go ahead and enable that. There are three different sliders, photo enhancement, enhance face, and scratch reduction. If I turn off the enhance face and the photo reduction, well when I toggle it back on, we can see that it is actually enhancing the entire image with contrast as well as edge detection and enhancement. Then let's zoom in using Command + 1 on Mac, Ctrl + 1 on zero. I'll use the Space Bar in order to navigate to this area here. I can toggle on the enhance face and we can see that Photoshop creates new pixel information for that face based on the original. Now, I think we've gone way too far. In fact, I'm going to lower this down to about 28, because while I like the effect, it didn't blend well with the background, I need to add back in a little bit of noise. Otherwise, if this is too high, the skin tone here is going to be too smooth to match the background. This image really doesn't have any scratches, but if it did, we could add the scratch reduction as well as additional adjustments for noise, color noise reduction, half tone artifacts and JPEG artifact reduction. At this point I would be tempted to move right to the colorize Neural Filter. However, I'm going to apply this on a separate layer. So we can see that I can output this to a smart filter, I'll click OK, and we can see the smart filter in the layers panel. I'm going to use Command + J on Mac, Ctrl + J on Windows in order to duplicate this and then to edit the Neural Filter, I'll just Double Click the Neural Filter in the layers panel. I'm going to remove the photo restoration on this layer, and instead enable colorize. Then when I'm finished colorizing this, I can switch the blend mode of this layer to color, so we only see the color effects from this layer, and we'll see all the gray scale values from the layer below. We can see that Photoshop has automatically colorized the image. We have a number of different controls on the right hand side. We can choose from these different presets or profiles. However, at the time of recording, I seem to be getting an error, so I'll reset that. I do feel that the entire image has too much red in it, so I'm going to move the cyan red slider over to the left in order to remove some of that red. We can also decrease or increase the saturation if we think that Photoshop has used too saturated of colors to colorize our image. I'm also noticing some color artifacting in the witch's cap, so I'm going to increase the color artifact reduction slider until I no longer see those magenta artifacts. We can also manually color the image, all we need to do is click in order to set down a focus point. Then I can select a color, here, I'll choose red for her shoes, and then reposition it as needed. If I want to make the other shoe the same color, I can hold down the Option key on Mac, the Alt key on Windows, and then drag a copy of it. I can also remove colors in the image. Here, I don't like the orange in the sidewalk, so I'll click to set down another focus point, click in the color swatch, and then decrease the saturation to zero, and that will remove the color from that area. I'll hold down the Option key again, Alt key on Mac, and drag that over to the left of his boot to decolorize this area as well. Excellent, let's apply that and then in the layers panel, I'll set the blend mode to color so that we can see the photo restoration filter below. If I want to make edits to the color, for example, maybe I want to remove some of the orange from the hair, I can use the smart filter mask. I'll tap the B key to select the brush tool, we can zoom in and I'll tap two to give me 20%, get a little bit smaller of a brush and tap the X key to make sure that I'm painting with black, and then I can just paint here in the hair area in order to remove some of that yellow color. Let's just paint over here, and of course, if I paint too much, we can always tap the X key. That will give me white as my foreground color and I could paint to reveal the contents of the smart object. I'm also going to select the lasso tool, and I'm going to select this area of green here on the fingers. I'll hold down the Shift key in order to add to my selection and select these fingers. And then instead of making an edit on this layer from the bottom of the layers panel, I'll choose the solid color fill layer, use the eyedropper in order to sample the color, apply that, and then change the blend mode to color. In order to soften the edges, I'll target the mask in the layers panel and add a bit of a feather. Excellent, let's move to the next image, which is a portrait. Again, I'll use filter and then convert for smart filters, and then filter and Neural Filters. I'm going to zoom into 100% using Command + 1, and then I'm going to apply the skin smoothing filter. Here we have two sliders for blur and smoothness. I'm going to increase the blur amount, but then decrease the smoothness. I have rather sensitive skin, so it's great to be able to have Photoshop automate the skin smoothing for me. We can toggle the preview, there's before and there's after. It's very similar to adding a more diffuse light when the portrait was taken. Some of my additional favorites are the landscape mixer that can help change the time of day as well as the season, and you can even use a reference image. Harmonization can help match color and lighting conditions when you're compositing layers together. Super zoom can help us to enlarge images and we can also remove JPEG artifacts. Many of these filters also ask for feedback after they've been applied so that Adobe can improve the AI model that's used to create the information. And if we click on the wait list option, we see a number of filters that if you're interested in having Adobe develop, you can click I'm interested. All right, let's output that to a smart filter. And the next time that you want to quickly restore and colorize an image, soften skin on a portrait and more, be sure to check out the Neural Filters.
