This image was entered in the Patterns Around Us competition along with my Autumn Leaf but this was my favourite one because of the strong colours and unusual contrasting effect.
How I did this: take an ordinary photo and clean it up, fixing levels and all the usual things. Duplicate layer, then play around with the top layer and the curves tool, creating a curve with two waves. You’ll see unusual rainbow hues and the colours will be distorted in other ways too. Now, change the mode of the layer. Each mode will make the image look different, but I settled on “Grain Merge” for the final effect here.
PS. the Blogger’s Dinner last night was most excellent. Luigi’s staff did an outstanding job at creating a tasty meal!
