Maybe you that follows my blog have seen this landscape before. Actually the Arpoador is a cliché of the city, that is, not only in my blog, but in any postcard or reference to Rio de Janeiro. I was passing nearby and I finally decided to use the variable ND filter I had bought months ago for a long exposure photography. I tried six or seven shots, and curiously the first one was the best. [ISO 50 – F22 – 28mm – 20 sec]. But I soon realized that I have a lot to improve on this long exposure technique. I still need to understand the best weather conditions and the best time. I noticed that the cloud displacement could end up spoiling the photo. In this case here, it gave an effect that I consider the limit of acceptable; the others were a bit ugly when it came to capturing the movement of the clouds. Which leads me to think that a day of complete clear or completely cloudy skies are better components for this type of photography. I want to study this subject further.
