Wear and tear (the third of the themes), the effect of time on materials like stone, wood and metal, can create beautiful abstract images, often resembling abstract paintings. Like with most of these themes, it is essential to keep an eye open for suitable subjects. As an example, every time I come into an old European church, I look at the pillars and the walls, for possible abstracts. Another example one frequently encounters is rust, especially when it occurs in combination with painted metal around it. Although there may be shapes and line play at work here, more often than not, the abstract effect comes from combining different colours, so black and white conversion is almost never a good idea for this theme. On the other hand, pushing the natural colours to extreme levels often lead to excellent results.
