My creative practice this morning has been spent on creating photo mandalas, and here is the result of the mandala I created out of a photograph of my backyard labyrinth.
To create this, I started with a square photograph in Photoshop. I mirrored the photograph four times, as shown on page 98 of The Creative Photographer, I then duplicated the layer, rotated it 90 degrees, and changed the blending mode to lighten. I then duplicated this layer, this time rotating it 45 degrees. For the last step, I duplicated that last layer and rotated it 90 degrees. And there you have a mandala!
And if you want to make it circular, use the Elliptical Marqee tool. Holding down the Shift key select the circle and drag it onto another layer.
