This a fractal image i done for one of the elements inmy request art deviation.
You are free to use it as stock, only where there is no violence, people getting hurt and gore , everything else is fine... and i am not fussy about..
To use it, in photoshop, use background eraser brush, set it to discontinuous and the tolerence to 50 or 65% and click on black areas to cut around the fractal. You will note dark areas get more transparency and the lighter areas stay the same.
Then paste over your manipulation and do whjat you want with it.
Love and hugs
