Ok, I’ve been pondering this and I remain baffled. This image is about 10% of full frame - of an image I’ll be posting soon. It’s cropped from an image of rushing water, a little white water that of course creates random splashes and drop of water.
Why, why is the stream of water broken up in equal little segments? I’m assuming this is a water droplet flying through the air. Why doesn’t the camera record the streak? The shutter speed is .3 sec. I don’t think any other tech info is relevant? but I could be wrong.
Why does the smooth water (non-specular highlights) record smooth and contiguous as one would expect with longer shutter speeds, but the water droplet doesn’t? Ok, with the smooth water, it’s simply a continuous feed of water molecues recorded during that .3 sec giving the “illusion” that the water is flowing smoothly - but in reality it’s thousands of molecules added together… ok, I think I get the smooth water part.
Still am unable to understand why the flying drop is recorded in this way? I can think of a jet flying across the night sky and it records the blinking red lights and they come out in a similar display. However the planes red lights are blinking… so that makes sense.
The water drop travels a certain distance in the .3 seconds. Why is it not recorded as a smooth line?
I’m no physicist… and I’m hoping someone can help me understand.
Just thinking about this… it has to be mechanical on the camera side of things. Perhaps it’s the duty cycle of the sensor? Kinda like refresh rates for video?
Anyone have a clue?
