A story behind: Photography is all about light.
Three main rules govern the appearance light for photographic purposes.
Rule number 1. Quality of light: The larger the light source, the softer the light. Direct light from the sun alone will be much harsher than light coming from the sky covered with clouds ( look at the picture above ).
Rule number 2. Reflected light. Direct light is basically colourless but the light bouncing from the clouds at different level and the water surface takes the colour of the structure off which it bounces ( look at the picture above ).
Rule number 3. Intensity of light decreases in a manner inversely proportional to the square of the distance between the light source and the subject. In landscape photography this rule can be important when the light bounces for many times decreasing the quality.
That was a wonderful night for me at Murtosa, a night when shooting photos gives you a real pleasure.
