@robz I'll tell you mine if you tell me me yours on those abstracts you've hust posted...cheap prism positioned between camera and lens...that's it! Secret's out!
@granagringa So there is an external lens being used with a triangular prism? Still a bit lost - where is the light coming from? I'm trying to imagine a lens diagram in my mind - too much coffee I think LOL Anyway - the orchid abstract - one was basically SOOC!!! From a cropped section of a SOOC anyway LOL. That was the colourful one. The other was a close up of the centre of one orchid twirled one way. Then I had a photo that formed part of the "blind side" abstract - it was a set of blinds with lightened edges on each blade - the edges were coloured and then a Transparent swirl was applied and coloured a different colour. This was placed under the first twirled orchid image and the whole lot was twirled the other way.This is the first time I've thought to do a double twirl of two composite images - I was quite pleased with it. That's it here - second secret out!! Cheers for now! :)
