About 75% of the time is purely random explorations --push this button, twiddle that dial (I call it 'play' LOL!).

But I do subject almost all my play results to what I call my 'Rorschach test', and if I see something neat I'll move in and do some special tweaking to develop the picture some more in the direction I want to go. Not always easy, as I'm not a math whiz, and can't always predict which adjustment will go where I want to go.
For every pic I finally render, I usually have about 10-20 parameter files saved, showing the path I took to get to the final stage.
