Here's an effect which may be useful when you feel like adding some rustic grunge effects
to an image using my Used Canvas textures which are some hefty downloads in MBs.
Final image was composed by using "Used Canvas 2" as layer one, set at "Multiply" mode
set at 80% opacity. Then "Used Canvas 5" was applied as layer two, set at "Soft Light"
mode and opacity at 82%.
