‘Schlieren Optics’: the most impressive video about Schlieren Photography so far


Those of you interested in more information on the function principle of Schlieren Photography – a photo technique by means of which air movements can be visualized – should read this blog entry written by me. The embedded video there is short, but very insightful. Unfortunately, it is rather theory-loaded and contains few photos taken with the aid of this technique. For this reason, it may be less interesting for photographers and photographers’ eyes longing for “eye candy” and inspiring content. Fortunately, the following video from the YouTube Channel Harvard Natural Sciences Lecture Demonstrations offers far more in this respect. Nothing is explained, but footage that really takes your breath away is presented. Remarkable in particular is the fact that the items causing the air movements can be regularly seen. Usually, they are depicted as silhouettes. How this is achieved, I don’t really know. All I know is that I won’t ever see my hair dryer with the same eyes again, after having watched this video. 😉
