Main F.stops:

The main f stops in your camera are 2.8,4.0, 5.6, 8,11,16,22, 32.  for each increase in f stop value the amount of light entering the camera is reduced by a half.

Shutter speed.

Measured in fractions of a second.

1/500s  1/250s  1/125s  1/60  s, 1/30s  1/15s,  1/8s,  ¼s,  ½s,      1”    2”  4”….

Note: reducing the shutter speed from 1/60th of a second to 1/30th increases the amount of  light exposure by a factor of 2.

The numbers highlighted in orange would begin to present some blur in the image.

•WHAT IS SLOW SYNC FLASH?

•Slow sync flash is just a fancy term for using your flash with a slow shutter speed. It helps you keep your subject sharp while capturing motion or a dark background. That's it. Simple, isn't it?

•You see, with a normal flash photo, the shutter is only open for a fraction of a second, so the flash is firing for most of your exposure.

•With a long exposure, your camera's shutter is open for much longer than the flash is firing - perhaps even several seconds.

•You can choose whether you want to fire the flash at the start or end of the exposure.

•Firing the flash at the start of the exposure is known as "front curtain" or "1st curtain". Firing it at the end is known as "rear curtain"

Relationship between shutter speed and aperture.

These are some images I shot in the studio capturing blur and movement.
