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.
There are a few other tabs here in the Camera Raw window that you may not use as often but I do want to introduce you to them so that you know what they have in case you need these controls. Right now I am in the Detail tab, which is the third one from the left. From here, you can sharpen the image and reduce noise in an image. I talked about digital noise in another movie on reducing noise inside Photoshop proper and as I mentioned there, there are two kinds of possible noise in a digital image. Luminance noise looks like black and white grain and color noise looks like little specks of color.
You can reduce either kind of noise using these sliders but be a little conservative because when you do drag either slider to the right, you tend to blur the image. From here you can sharpen an image using controls similar to those in the Unsharp Mask filter in Photoshop proper, which I covered in another movie on sharpening. But you should know that there are some people who don't like to sharpen here in Camera Raw but rather prefer to sharpen only once at the end of their entire editing workflow in Photoshop. So they will take an image from here in Camera Raw into Photoshop, make some edits, resize the image, and then sharpen the image there.
If you are among those people, then you want to turn off sharpening here in Camera Raw. To do that, you can go to the Preferences icon right here, to open the Camera Raw Preferences and where you see Apply sharpening to All Images, click and choose Apply sharpening to Preview Images only. That will make the preview of the image here in Camera Raw look sharp, which will help you to correct its color and its tone, but there won't be any actual sharpening taking place. So I will click OK here to accept that setting.
Here is another tab. This is the Lens Corrections tab. From here, I can control the vignetting or light or dark areas at the corners of an image. And I also can try to remove chromatic aberration. Chromatic aberration looks like red or cyan or blue or yellow fringing at high contrast edges in a digital image. You can see some red fringing in this image over here on the left side of the skull. I am going to zoom in so you can see that better by selecting the Zoom tool and dragging over that area.
There is the red fringe. I can remove that fringe by going to the Fix/Red Cyan Fringe slider and dragging to the left until the red fringe goes away. When you fix chromatic aberration, you do want to go back to 100% to see how the image looks with the fix. So I will double-click the Zoom tool to do that. Good, I like that result. So I will go on to show you what's behind these other tabs. You can use the Camera Calibration tab to try to counteract any idiosyncrasies of your particular camera and the way that it's handling color here in Camera Raw and if you go to the Presets tab, you can save out any or all of the settings that you've adjusted in this particular image so that they could be applied to another image.
To do that, you go to this icon at the bottom of the tab, click, and in this dialog box, choose the settings that you want to record as a preset. I will leave all these selected and I will give the preset a name, and then I will click OK. And if I opened another image that had similar issues to adjust, I could just come to the Presets tab and click on the skull's preset to apply all of those settings. So that's a quick look at what's available to you under the Detail tab, the Lens Corrections tab, the Camera Calibration tab, and the Presets tab in the Camera Raw window.
