Rotating the circle fast enough by ensuring you would see 10 or more frames in 1 second, would mean that you see enough frames for persistence of vision. Actually creating 10 frames is not necessary as it rotates through them constantly. As long as you rotate the circle/frames fast enough, your eyes will be deceived into seeing movements within the phenakistoscope. If you only drew four frames in the phenakistoscope, you would have to rotate the circle 2.5 times in a second, and you would see movement. If you drew 10 frames and rotated the circle fully once in a second, you would think the pictures made up full movement.]]> 2018-01-23 13:50:54 UTC https://padlet.com/Harry_BALDWIN/newnptihiy4b/wish/223764791 Harry_BALDWIN https://padlet.com/Harry_BALDWIN/newnptihiy4b/wish/223792805 Persistence of vision is the technique of presenting someone with 10 or more pictures (with continuity of movement) so they see the illusion of movement. The brain takes 0.10 seconds to see and process an image from the eyes, this means you see each image, one after the other, as fast as your brain can process it if 10 frames are shown in a second. If you see more frames than 10 in a second, the persistence of vision illusion with continue further, getting more smooth as you increase the amount of frames. Frame rate and persistence of vision directly correlates. If you had 30 frames in a second the persistence of vision would be greater, increasingly fooling your eyes into believing what you are seeing is actually moving. Most movies are 25fps, as to not overwhelm.]]> 2018-01-23 14:39:25 UTC https://padlet.com/Harry_BALDWIN/newnptihiy4b/wish/223792805
