Apple has published its latest Aperture tutorial, this time exploring the colour editing tools of the application.

The tutorial was written by former MD of The Association of Photographers (AOP), Jonathan Briggs.

'More than just grayscale' looks at Aperture's advanced and non-destructive set of tools for moving RGB images into black and white and beyond, offering step-by-step instructions.

This is the ninth Aperture tutorial to emerge from Apple so far.
