An Easy Way to Colorize One Part of a Photo with Photoshop
Today I am going to show you how to add a cool effect to your color photos to make on specific feature pop out more than any other part of the photo.
The first step after you open your photo in photo shop is to use the Rectangular Marquee tool. Using this Marquee tool, copy the entire photo. Warning: You may not be able to right click if on a PC, so be sure to use your keyboard short cuts to copy this photo.
After you have your photo copied, create a new layer using the sticky note button on the bottom of the layers window.
Now with your new layer selected, paste the copied photo into the layer. Now you have two layers of the same image, for the remainder of this tutorial, we will only be working with the top layer.
The next step is to drain the the saturation of the top layer. By going to the Image tab -> Adjustments -> Hue/Saturation ,the Hue/Saturation options will appear. Using the slider located under the word Saturation, slide it all the way too the left until the photo becomes black and white. Click Okay.
You should now have two layers, one which is in color (the background layer) and your new layer which is in black and white.
Using the eraser tool, begin to erase away the parts of the image that you want to be in color. WARNING: It is VERY important that you are working on the top, black and white layer of the photo!
Continue to erase the parts you would like to have in color, and Voila! your photo has specific features that will pop out to your viewers!
