There are no rules as to how you apply your post processing to this image; but, please let us know what you have done so we can all learn. If you would like to post a candidate image next week, please ensure it is of sufficiently high resolution for manipulation by the participants (3000px on the long side, 300dpi for example). Most of all, let's have fun while we are learning or demonstrating how we use our post-processing software, imaginations and interpretations. In Austria, I think.

Excellent call on the challenge image, Punta. Version 1 - All work in PSE2020. Cropped from left edge and resized to create square crop. Sharpened using sharpen tool.
#2 Again, everything in PSE2020. Inverted Version 1, then solarized. Finally used sponge filter to create fine art appearance.
Topaz Simplify plus black and white background layer in Photoshop CC. Added a photo of a friends dog and the can of Red Dog ale. Selected dog using Topaz Remask 5.
