A study in the effects of sunlight and shade

Between this morning's showers there have been a few spells of bright sunshine.

To heighten the 3D effect in this photo I have shot it at right angles to the sun, and applied a generous dose of sharpening. The background was provided by a convenient sheet of mounting board.

There are major colour and brightness changes between those parts of the flowers in the sunlight and those in the shade. The mounting board is in the shade.

You probably wouldn't think to ask what colour the mounting board is, but I shall tell you anyway. It is pure white: a study in the effects of sunlight and shade.
