I really liked the smooth colourful results, so of course, I had to try as well.
In his tutorial, Peter talks about the importance of choosing the starting image carefully. He is right!
Even the smoothest water image I had produced some horizontal lines in the final result. However, I found that I could cheat a bit and add a step or two before applying the motion blur.
I used this sunset shot as a starting point .
Using the rectangular marquee tool in Photoshop, I selected the lower part of the image, from the horizon, down. I feathered the selection 10 pixels and applied a gaussian blur, with a radius of 8,8 pixels. I repeated the process for the upper part of the image (from horizon, up). Now it was time to apply the motion blur as described in Peter’s tutorial.
