When to convert
■ You can choose to record a black-and-white image in-camera, or shoot in colour and go grey later in editing software. The advantage of starting with a colour image is that you get more control over the conversion. You can manipulate individual colours to boost or reduce the contrast between different parts of the picture; and if you don’t like the end result, you can revert back to the original colour image.
If you set your camera to mono shooting while you’re recording in JPEG, a black-and-white version of the image will be saved to the memory card. Shoot in raw, however, and you get the best of both worlds: a file that contains all the original colour information so that you can do more sophisticated editing, and the opportunity to preview a black-andwhite image while you shoot.
