Hi all!!
Well this photo is basically a bit of fun with GIMP. I saw this tree in Rockdale Bicentennial Park on my early morning walk last Saturday whilst in Sydney. I loved the shape of it but couldn't really get the shape to stand out in colour or B&W. So in the G'MIC plugin in GIMP I noticed a Charcoal filter which I applied to the B&W image. Again not quite what I was after so I inverted the image and got this result. I've called it my "chalk" version as that's all I could think of as an inverse of charcoal!
Now just a quick bit of history - Rockdale Bicentennial Park was a tip when I was growing up and after a quick search on Google I discovered the area used to be known as Pat Moore's Swamp. For those familiar with the area, Moorefield Girls' High School used to be a racecourse that was built by a Peter Moore, grandson of a Patrick Moore who settled in the area. These swamps can still be traced from the park through to Scarborough Park, although they're more like waterholes now. I've attached a satellite image to this post as well - the photo overlays a map from around the 1880's - I found it very interesting...
Cheers,
Mario
