This sounds very, very helpful - thank you Sivason - I can imagine myself doing it!
You know - I choose this changing as a task for the competition - it was okay to look away - but I really felt as if there is something important and profound to be learned for it - because I was completely clue-less - just fiercely expecting it didnīt overrule my expectation of the optical field as you say.
I rather was on about getting to see it all clearly and realistically - this idea with the wet oil painting for all reality - this sounds very powerful.
Great - thank you - I will report, how this plays out!
