Psychedelic Creeper

I mentioned in my last post that I often use the digital filter function on my Pentax to take what are essentially black and white photographs but leaving highlights of red.  When we got back from our walk around Mountain Drive today I thought I would try something a little more complex and take black and white photographs but leaving in two colours.  We have a beautiful creeper in the courtyard that flowers in purple and yellow so I played with the filter to see if I could get just those colours and leave all of the foliage in black and white.  The first attempt gave a gothic-psychedelic result which is quite splendid but not what I wanted at all!  The second picture came much closer but just doesn’t have the same impact.  By-the-way I think the creeper is a type of Acanthaceae (Barleria Repens) ….
