Photoshop has become an indispensible tool for photographers, designers, and all other creative professionals, as well as students. Photoshop CS4 Essential Training teaches a broad spectrum of core skills that are common to many creative fields: working with layers and selections; adjusting, manipulating, and retouching photos; painting; adding text; automating; preparing files for output; and more. Instructor Jan Kabili demonstrates established techniques as well as those made possible by some of the new features unique to Photoshop CS4. This course is indispensable to those who are new to the application, just learning this version, or expanding their skills. Example files accompany the course.
Another one of the useful tabs in the control area of the Camera Raw window is this one, the HSL/Grayscale tab. In this movie, I would like to show you how this tab works and also its neighbor, the Split Toning tab. I am going to go back to the HSL/Grayscale tab. HSL stands for Hue, Saturation, and Luminance. Hue means basic color. Saturation means the intensity of a color and Luminance is about the brightness and darkness of the color. I can vary each of these properties of color separately for individual colors in the image.
Everything from Reds to Oranges to Aquas and even Purples. So for example, let's say that I want to play with the color of these peppers. I am going to click on this Luminance tab, and from here, I am going to go to the Reds slider because those peppers are obviously red and if I want to make them brighter, I am going to take the Reds slider and I am going to move that to the right to brighten just the reds in the image. If I move this slider to the left, the reds would get darker. Now let's say I want to change the color intensity of these reds.
I will click on the Saturation tab, and I will grab the Reds slider again and I am going to move it to the right to increase the saturation of just that color in the image. There is a little bit of red down here as well and that's also increasing but I can live with that for now. Finally, I am going to go to the Hue tab and say I wanted to change the color of these red peppers entirely. I will get that Reds slider again and I will drag it over to the right and I can change the color of those peppers to orange. If I move the other way, I can change the color of the peppers to a different color.
Now the other function of this panel is to allow me to make a grayscale conversion right here inside Camera Raw. All I have to do is click Convert to Grayscale and then I can fine-tune this Grayscale mix by going to the individual color sliders and moving them. So if I want the peppers to look lighter in this Grayscale conversion, I will take the Reds slider and I will move it toward bright and you can see where bright is by the coloration of the scale. I think there might be some oranges in the rest of this image. So I am going to try moving the Oranges slider to the right and that lighten some other areas of this Grayscale conversion.
This tab gives you a lot of control over converting a color image to Grayscale. If you are preparing an image for use in Photoshop, you might want to do your Grayscale conversion here, rather than wait till you get into Photoshop, where you can use the Black & White Adjustments panel. One of the reasons is you have more colors to work with here in the HSL/Grayscale tab than you do in the Black & White Adjustments panel in Photoshop. I would also like to show you the next tab here, which is the Split Toning tab. I can use this on a grayscale image or on a color image. And what it does is lets me add a monotone colorization to the highlights in the image and a different one to the shadows.
To see how that works, I am going to go to the highlights area and I am going to drag this Hue slider into the orange-yellow range. Then I am going to take the Saturation slider for the highlights and drag it to the right and now you can see a monotone orangey-gold in the highlights of this image. Then I will move to the shadows area and I am going to choose another Hue for the shadows. I will drag the Hue slider all the way over to the Blues and then I will increase the saturation of that color in the shadows only and that gives me the split tone effect with blue shadows and gold highlights.
I can take the Balance slider and play with that in order to vary the balance between the blue shadows and the gold highlights in the image. So those are some ways to alter color inside of Camera Raw from the Split Tone panel and from its neighbor the HSL/Grayscale panel.
