Over on one of my other websites I have published three Photoshop tutorials, often when I read tutorials they might say something like , ‘now use the Channel Mixer’, sometimes I do not have a clue as to where the channel mixer is on the menu structure, and the text often assumes you understand what it is talking about.
When I write a tutorial, support email or training aid, I will often insert an image rather than text, I think that an image is a far better reference point and a visual descriptor.
Black & White Lab Color Method
There are many ways you will read about to convert a colour digital image to Black and White, there is the lazy way of just performing a de-saturation or just selecting Mode and Greyscale, I use a method called the Lab Color technique, there are several steps to perform, but I feel that I have more control over the final image.

Remove Purple Fringing
You may have heard the term purple fringing, and it can become evident when you view a high contrast image at 100%, this fringing may appear purple, blue and even magenta or other colours, purple fringing is the most used term.
Usually this is caused by low light against high contrast areas in an image, the fringe colour range is a fairly narrow band and can be removed in Photoshop.

Removing stray areas Isolation over White
Sometimes no matter how hard you try to get a clean background with a product or model shot, which is an Isolation over White, often you do not see the stray area until you make a print and see the defects in the background, in this tutorial there is a simple way to correct this using adjustment layers.
