I'm from Frankfurt/Main (Germany). I'm not a professional photographer. I take photos mostly only during my holidays.
The photos from Australia were all taken using a Sigma SD14 DSLR in raw format (.X3F) and then later converted to .JPG with the Sigma Photo Pro 2.1 Software (The Version 3.0 does not work properly on my Laptop).
In case you are interested in the photos in their original size, please let me know and I will e-mail them. Please be aware that .X3F have between 8 and 18 MB, .JPG have between 1 and 9 MB. Zipping does not help in reducing the filesizes.
