The most striking thing about an Agapanthus is its startling blue colour.
Desaturating the colour with GIMP, and selecting the shade of grey based on Luminosity, turned the flower surprisingly metallic.
I include the above as a sort of “also ran”! I was trying to drain the colour, but retain the blue. However, I couldn’t get the leaves to stop being so green. Inability!!
I don’t normally participate in WP events, but have made an exception here, in support of Ady, a young photographer, experimenting with a new camera. If you visit her blog colorpaletteofady you will see some great photos. A lot of my followers are blanketed in snow in the Northern hemisphere, so are actually participating in a monochrome theme already; no photo adjustments needed!
I will post a few photos in the monochrome series, but not necessarily consecutively. Keep an eye out for them!
