While looking for subjects for exercise 3.1, freezing movement; I tried an experiment comparing an image of a spinning fan taken with and without flash.
The images below are taken at roughly the same shutter speed but the flash seem to have almost frozen the fan’s motion.
It’s after you zoom in on the flash image that you can see the safety screen behind, almost super imposed on the fans blade.
55mm. 1/80th. sec. f 5.6 ISO 1600
55mm. 1/60th. sec. f 5.6 ISO 100
The effect is quite startling.
As it didn’t entirely freeze the fans motion I didn’t include it in my images for exercise 3.1, maybe practice some and include it in later exercises and assignments.
