I took my pictures near an open window. At 1/2000 and 1/1000secs the differences is not too noticeable but there is a little amount of blur. I started to see the difference in 1/100 secs. It starts to blur at the end of the pencil. At 1/50 secs speed starts to really have a speed line effect I was expecting. I really like the 1/15 secs image because it looks like it’s fading out of existence. I need to work on my ISO in the future. The images doesn’t look grainy but it does look dark for the first two images.
Good work. Daylight helps!
