Photoshop CS4 for Photographers is an essential course for any digital photographer who wants to master the software's vast array of image enhancement techniques. Professional photographer and instructor Chris Orwig uses his own compelling images to demonstrate how the power of Photoshop can make photographers more passionate about their work. He covers many aspects of the application, such as working with RAW images, using curves and levels, making images snap, and enhancing bland photographs by converting them to black and white. Exercise files accompany this course.
In this movie, we are going to continue our conversation about modifying color and tone. In particular we are going to talk about how we can replace color. We're going to be working with this file corwig_mexico. You can find it in the chapter 21 folder. Go and double-click it to open it up in Photoshop and press F to go to Full Screen View mode. Now replacing color is actually pretty fascinating, yet when we use the Replace Color command, we are not going to be able to undo our changes. So here's what I want to do. I want to copy my Background Layer and I'm going to do that by pressing Command+J on a Mac/Ctrl+J on a PC and I'll call this new layer new_color. Next I'm going to navigate to my Image pulldown menu and choose Adjustments and then Replace Color. This will then open up the Replace Color dialog.
Now here's what I'm interested in doing, I love to change the color of these ceramic pots and also this wall in our photograph to Mexico. So I'll grab my Eyedropper tool and I'll click on those pots. Now I can see that I have a small selection, I need to grab my next Eyedropper and slowly build that up. Now I can build that up here in this mask or over here. Now I'm going to build that up and now I'm getting close so I might as well shift my Hue. So I'm going to go ahead and shift my Hue to something very different and it's going to show me some problem areas so I'll go ahead and click and drag this cursor around these areas and slowly build up the change here. Increase the Fuzziness, which will increase the reach of it little bit there, and click and drag around the image. Make sure I have all these small little spots. Okay, that looks pretty good and that little edge over there, I need to get.
Now it's too far, Command+Z to undo that. Now with a little bit of spill over into the cements, so I'll grab my Minus icon my cursor with my negative icon, to remove those areas, all right. Those are now pretty well cleared up, and I think that's looking pretty good plus icon, and I'll going on to make sure I have that area there, and I want to get some of those areas okay. Well now I can modify the overall Hue and I'm just going to drag this slider one way and then the other and here you can see I have a number of different options and I can change their color. Now when I find the color that I like, and let's say I just want to make these may be a little more orange here, I can change the overall Saturation increase or decrease and also the Lightness and that's as it sounds light to dark, it's not darkened it up just a touch there. Little bit of Saturation and I want to find a color that looks interesting to me. Okay, that look is kind of fun, I'll Click OK.
Now here is our before and after, some pretty interesting color change. Now let's say also I want to change to the wall. If I want to change the wall I'm going to go back to Image > Adjustments > Replace Color and this time I'm going to click on the wall. Now I'll grab my Eyedropper which has a Plus icon next it, I'm going to go ahead and click around everywhere, in the image, I want to make sure I get all of these different tones. I can also click in the Mask and then at some point in order to check my Mask I need to modify my Hue adjustment.
I'll go ahead and modify that this way, make sure I have all of the background selected, de-saturate just a touch there, little bit brighter and then try out some different Hues and that green is kind of fun, click OK to apply that. Now I have created pretty, it's a real color effect. Yet none of that's kind of interesting, here is our before and after. So as you can see, you can use that Replace Color Command in order to dial in the specific colors. Now it's important that you do this on a new layer so that you have flexibility, because let's say at this point, I say you know what, I like this except I don't like the background, I just wish I'd change the colors of these two pots.
Well now I can grab the Quick Select tool and quickly paint across one, hold on the Shift key, paint across another and then click on the Add layer Mask icon, so now I have an adjustment which is just effecting those pots and let's say that I want to then change the color even further. Well check this out. We go to our Adjustment Layer we click on Hue Saturation, modify the Hue, then go back and close that for a moment and what we want to do is create what's called the Layer Clipping Mask, we have talked about this before. Hold down the Option key on the Mac/ Alt key on a PC, hover over those two lines. This adjustment now is changing just the color of those pots, you can also access out by going to your Adjustment Layer and clicking on this icon here so that you can limit that colors adjustment to the layer underneath it.
In this case I can fully change the color of those pots any which way and I can also control the overall Intensity of the color as well. Double Clicking the Adjustments Tab will close that in summary what we have done here. It is talked about how when you use Replace color to get it, I need to copy the layer because you need to the ability to be able to Undo what you have done. Then we've talked about how we can then Mask in specific areas so that we can just modify specific areas of our image and then finally we looked at how we can create what's called a Layer Clipping Mask in order to further adjust the Layer that we have modified.
