I can, of course, make the bubbles in PSP by hand and for some situations only the hand made ones will work.
Bubbles can represent many moods and life states and their ability to change shapes, rise and fall, and reflect surroundings are what strike chords in many observers.
In this photo I was trying for a non linear flow up and away from the observer on a path which seems to follow a current in a gentle upward spiral. The bubbles ascend as the sun descends in counter balance.
Very interesting shot Jim! I'm not a fan of the bubbles, but after reading your post it does make more since now. The photo is so powerful alone that I just think the bubbles are distracting. Just one oberservers opinion....
