Are you using the best method for converting photos to black and white? There are a number of techniques to convert a color image to black and white for your customers. Here are four basic methods:
- Color mode: With your file open, select Image > Mode > Grayscale. Click “Okay” to disregard the color information. This method is considered to be destructive, meaning the original file has been altered, and offers you no editing control.
- Adjustment: Another commonly used method is selecting Image > Adjustments > Black & White. This will convert your color image to a grayscale image. There are some sliders to allow you limited control on over-the-color editing as well as an Auto button. This technique, while giving a nice black and white image, is also destructive.
- Lab mode conversion: This technique changes the color mode from RGB to Lab. From the top menu bar, choose Image > Mode > Lab Color. You won’t notice a color change until you open the Channels window. In the top menu option, select Channels to open the window. Click on the Lightness channel layer; the other channels will turn off or hide. Next, convert the color mode by going to Image Mode > Grayscale. You can now change it to RGB for sublimation printing.
- Desaturation: Select Image > Adjustments > Hue & Saturation; a new window will pop open. Move the Hue slider all the way to the left (-100) to remove the color from the image. This can be applied as an adjustment layer, which is non-destructive.
