Introduction

All monochrome mages start life in colour. But straightforward conversion often results in a disappointing image rather than the magical black and white.

Objective

This workshop gives you the underlying knowledge to help you prepare an image for conversion into monochrome.

Format

The first half is an interactive presentation and club members are encouraged to join in and ask questions. The presentation covers the technical aspects of gamma, the histogram, what the black and white points are, and why that middle triangle wiggles around as one adjusts the other two.
Understanding these sets the scene for the conversion method. Photoshop has (at least) eighteen different methods for converting colour to mono. PS Elements has two (depends on the version) and a demo using the less common methods reveals some interesting effects.
