In Easter i make a trip to Madrid. And i think to my self, "great i can relax and i can visit a new country and make some pictures for stock!"
The sad part of the story is that in the first night at Madrid i take some pictures from some buildings and set the ISO to 800. The next day the ISO was still in the 800 and i don´t remember that. And of courser i don´t check the setup again and you now the rest of the story. I end up with lot of pictures taken in another country with lots of noise!!
What i want to said is that the preparation is so important as the pictures, place and light. If you don´t pay attention all the good pictures can turn into garbage!
In the end i can only recover 5 or 6 good images and get my car in the police station for bad parking and a fee of 165€. :)
