Black and white can be a great choice for an image particularly if your image is high contrast.
Best practice is to always shoot in color. Do not shoot with the black and white setting of your camera or cameraphone.
There are three ways to convert your images to black and white in Lightroom and Lightroom Mobile:
1. Presets
2. Profiles
3. B&W mix
Select one of your photos that has a good range of different colors in it. Create two different versions that look really different using any method. Put them in a post with the category Week 12 – Black and White.
