1. DESATURATE
   Image > Adjustment > Desaturate.
   As the name suggests, you are de-
   saturating (reducing) the colours but
   the effect is dull.


2. GRAYSCALE
   Image > Mode > Grayscale. You will
   be asked if you want to discard colour
   information. Say ‘Discard’ and you are
   done.


3. Hue/Saturation
   Open the Layers panel (F7 key on
   the keyboard). Create an adjustment
   layer for Hue/Saturation (Click on
   the half-black half white circle at the
   bottom of the Layers panel and select
   Hue/Saturation). Move the Saturation
   slider all the way to the left.


4. Gradient Map
   Open the Layers panel (F7 key on
   the keyboard). Create an adjustment
   layer for Gradient Map (Click on
   the half-black half white circle at the
   bottom of the Layers panel and select
   Gradient Map). The coloured image
   will turn into a B&W image with
   rather stronger contrast. Though this
   method is superior to the Desaturate,
   Grayscale and Hue/Saturation
   method, it still does not offer the
   control that we’ll see in the later
   methods.
