Dear friend, my great friend Bere asked to show to ours friend to the photoforum this technique. I use in my abstracts and I use to in "normal" shots. I love the effects but I prefer to use in macro/abstrats. It was only to show "negative art" that is one effect that i have in my camera. What do you think? Did you like? It is different like I love.rsssss But don't worry I will made only abstracts. I prefer.
