Lecture 15: Cameras & Lenses (65)

When a scene includes both stationary and moving subjects , a slow shutter speed can cause interesting effects, such as light trails. One application will be Star-trail photography. I found some interesting examples here


Another interesting example: drawing with light with long exposure photography! https://www.picturecorrect.com/light-painting-the-outline-of-a-person-with-long-exposure-photography/


One of my favorite photographers uses long-exposure photography but only in small amounts! He sets shutter speed to something like 0.1 seconds, so things are just blurry enough for the aesthetic. https://www.instagram.com/wrapped.nil/


Ha! I have been wondering forever about why pictures of cities at night such as this one always seem to have red lines of light on the roads instead of actual cars, but now I suppose it is because they are long exposure photos. Another interesting thing to think about then is why they are done that way. My personal guess is that they use long exposure photos because it creates more vibrant colors, especially at night, and the lines on the road are just a by-product.


Another common long-exposure exposure photography subject is the star trails, in which the camera is pointed toward the night sky for over 30 minutes, capturing arcs formed by the movement of the stars.


How do point light sources not become incredibly bright during long-exposures like this? For example, the light in the background has a lot of light being captured.
