I'm not really into arty farty stuff but this is what we were learning to do. After several failures I finally got the effect I was after and I have to admit I was quite pleased with it.
It'll be back to 'normal' pictures tomorrow.
I quite like it as an abstract -- it has a painterly effect and the muted colours of the purple to the green is a lovely soft combination !I haven't heard the term arty farty for such a long time -- but often use it myself !!
