I was lucky enough to attend a half-day workshop run by Renee Doyle, a photographer based on the Gold Coast creating amazing images from oil floating on water. Sounds odd, but it was great fun to play with, creating unexpected results.
I have included some of the images I created on the day (with a fair bit of editing in Photoshop afterwards).
If you would like to check out some of Renee's work, you can find her at Renee Doyle Photography (https://reneedoylephotography.com) and her instagram is https://www.instagram.com/reneedoylephotography/ Along with a number of short workshops, she also runs tours to a number of locations including Africa, Alaska and Costa Rica.
