Black and white photography is sometimes treated as the 'poor relation' of colour photography. After all, why limit yourself to shades of gray when you can use the entire spectrum of colours?
In the 'good old days', when we had finished the day's photography, we would disappear into the darkroom and spend hours breathing in the fumes of nasty, smelly chemicals in the pursuit of our art, now we have Adobe Photoshop.
Light not only has direction, it can be direct or diffused. Direct light, light coming mainly from one direction, produces relatively high contrast between bright highlights and dark shadows.
The rise of consumer priced digital SLR cameras has generated a great new following in photography. Amateur photographers find they now have more control over their photographs and ample opportunity to experiment outside the ‘point and shoot’ mentality. No longer do they have to wait until the whole roll of film has been exposed and then processed, often finding that the exposure wasn’t right on that one, or it was out of focus on another. Now the shots can be viewed immediately and appropriate corrective steps taken at relatively little cost. No longer ‘a moment lost’.
