Some people work in a office all day, some people work with sparks
Catching the sparks from the fire is easy. You just slow down the shutter speed and you will have long sparks coming out from the fire, instead of small dots. Check the below pictures to see the difference between fast and slow shutter speed.
In these pictures I am using a shutter speed of 1/10 to 1/13 of a second.
I have croped out a little part of a big picture to only focus on the worker. So the sharpness might not be so good since he was pretty far away when I took these pictures. If you are wondering what he is doing then he is removing s steel pole. These pictures are taken with Canon 6D (full frame) and 24-105mm lens at f4 and f5 with ISO100 to ISO160.
When is it usefull with slow shutter speed?
- when you want to create cool light messages. You can write words with a flashlight and using slow shutter speed to create bright letters
- when taking pictures of fireworks
- if its pretty dark out and you want the picture to capture more light then slow shutter speed is a option, dont forget to use a tripod
- when taking pictures of cars head ligths or tail lights on a road, you might have seen the night pictures of red or yellow lights that are like lines on the roads. That can be made from very slow shutter speed
To control the shutter speed you can use the option called TV (Shutter Priority Mode) on Canon and S on Nikon.
