Going dotty

Here's another layered image. It started out as two pictures of the pierced metal sides of a pedestrian walkway over a nearby road. My original images just look like the grey steel it is made from but by layering them and then boosting the saturation, subtle colours within it become much more vivid. It's fun to do but it makes me think that designing curtain fabric or wrapping paper must be a complete doddle these days. It only takes a few minutes to create something like this. Dotty!
