The effect of a black and white image with a splash of colour is a popular effect used in photographs and images especially for adverts in magazines and on the internet. This tutorial will teach you the basic instructions for different ways to achieve this effect.
1.) To create an image to grayscale you need to begin by creating a duplicate of the original image, and then convert the duplicate image to grayscale by using the option Image > Mode > Grayscale, and then convert the grayscale image to RGB.
2.) Use the appropriate selection tool to select only the portion of the image that you want to have in black and white in your final composition. What we are doing is creating a “hole” in the grayscale image so that the colour image shows through the hole when the two images are combined in the next step.
3.) Combine the selected portion of your grayscale image with a duplicate of your original colour image. One simple way to do this is to copy the grayscale selection and paste it on top of the colour image then combine/merge the two.
4.) Make a duplicate of your colour image and work with it. Mask (protect) the portion of your image that you wish to remain in colour.
5.) With the mask in place protecting the part you want in colour, desaturate your image. The masked portion will remain in color. Image > Adjust > Desaturate. Do any other manipulations you care to make then, if the image is destined for print, convert to CMYK before placing the image in your page layout program. As a RGB image will not create the same given effect.
