There are lots of ways to manipulate color in Photoshop to make some interesting creative effects with your images. One of those is to use the Colorized feature in the Hue/Saturation adjustment panel. To show you that I'm going to add a Hue/Saturation adjustment layer to this image by going up to the Adjustment panel and clicking the Hue/Saturation icon, then I'm going to go to the Adjustment panel and there I'm going to click the Colorized check box. When I do that the colors in the image changed to the monotone, all different tones of the same Hue.
I can adjust this effect by going to the Hue slider and dragging it perhaps over to the blues or to the cyans or down into the orange range to create a sepia tone. I can also adjust the saturation of the effect by moving the Saturation slider, making it a little more saturated or less saturated. I actually like to keep the saturation down when I'm colorizing, I think it creates a more realistic effect. So I'll leave it there. I could stop here, but that's not all that I can do. I can bring back some of the color into this image, to make this look like an old fashioned sepia toned and hand painted photograph. To do that I'm going to use the layer mask here on the Hue/Saturation adjustment layer.
I'll make sure that the mask is selected, and if it's not, I'll click its thumbnail right here. Then I'm going to go over to the Toolbox and I'm going to select my Brush tool. I'll make sure that my foreground color is set to black, if it's not I'll just press the D-key and then the X-key on my keyboard, and then I'm going to come into the image and start painting on top of this horse. And wherever I paint, I'm masking away the sepia toning and bringing back the original color on the Background layer in the Layers panel.
When I'm all done painting on this mask, the image will look something like this. The horse and front will be in color and the rest of the image will retain the sepia tone that I created using the Colorized check box in the Hue/Saturation Adjustment panel. Now I can go in to the Masks panel and reduce the Density of this mask, to bring back a little of the sepia toning in the colored areas. The Masks panel is here in the Adjustments and Masks panel group. If your Masks panel isn't open, you can go up to the Window menu and down to the Masks to open it. I'll click on the Masks panel tab, and here in the Masks panel I'm going to lower the Density of the mask on the Hue/Saturation adjustment layer.
First I'll make sure that that mask is still selected as it is and then I'll go to that Density slider, and I'm going to drag it to the left. I'll lower it to about say 60%, and to show you the result of that change, I'm going to hold down the Option key on my Mac or the Alt key on a PC, as I click on the Hue/Saturation layer mask thumbnail. You can see that this is the area that I painted with black, and I have lowered its density, so that it's gray instead of black. So it's letting some of that sepia toning back and mixing with the color. I'll Option or Alt-click again, on that layer mask thumbnail, to go back to the full view of my image. So that's one way that you can take an ordinary image like this one, and change it into something that you might call a piece of art, like this one.
