Technique 34: Creating Grayscale Images: Your Choices and the Results
Save Time By
Checking out grayscale options
Doing the conversion
Fine black and white photographs can be truly wonderful. If you’ve ever seen some of the great Ansel Adams photographs of Yosemite Valley, you know what I mean. While few of us walk around with black and white film in our cameras these days (actually, I can’t remember when I last used film), you can convert color images into good-looking black and white images in Photoshop.Black and white images in Photoshop are called grayscale. Because these images are made up of 256 levels of gray, from black (0) to white (255), calling them grayscale makes a certain amount of sense.You need to know, however, that the easiest road to grayscale is not necessarily the best way to create a fine-looking grayscale image. You can use several methods to convert a color image to grayscale in Photoshop:
Converting a color image by switching from a color mode, such as RGB or CMYK, to Grayscale color mode. This method is indeed the easiest of the three. However, the results sometimes aren’t optimal. Many times the finer details of the image’s darker areas lose definition and can become muddy.
Selecting one of the grayscale channels that make up a color image. This method can work quite well because you retain fine details.
Using the Color blending mode and a solid black fill layer. This method usually creates a great grayscale image.
Which method you decide to use depends upon your image and the amount of time you have to test results. Comparing the figures in this technique to see the difference between grayscale conversions may help you decide which method to use.
If you’re interested in adding a bit of color to your grayscale images, take a look at Technique 35. There I give you directions on how to colorize grayscale images to accent and emphasize important features in your photographs.
