I'm reading a blog by my3boybarians called 31 Days To A Better Photo and today's page (Day 3) was Shooting Fast vs Shooting Slow. Day 1 was "Welcome" and Day 2 was "Find Your Camera Manual."
Shutter speed refers to the amount of time your shutter is open to allow light to enter. It is measured in fractions of a second. Shooting fast freezes time, while shooting slow allows a longer exposure.
"Imagine you’re at the sink with a small cup. You want to fill the cup with water.
So you reach for the faucet. If you leave the water on too long, the cup will overflow and spill.
If you don’t leave it on long enough, your cup will not fill." -my3boybarians

Today's "assignment" was to:
- Put your camera in manual mode. Lock in the same ISO and aperture – keeping them the same.
- Find a subject, take several photos, changing the speed 1 click on the dial each shot; watch what happens to your photos as you change shutter speed.
- Pay attention to how shutter speed can effect the amount of light in your photo.
- Pay attention to how shutter speed can show or freeze motion.
I decided to try this inside and outside, so I could compare the difference in different light settings. All of these images are with a Canon EOS Rebel T2i with a focal length of 18mm.
My son's Scout dog was my inside "model." lol
| Fstop-f/5.6; ISO-400; shutter speed-1/4 sec |
| Fstop-5.6; ISO-400; shutter speed-1/20 sec |
| Fstop-5.6; ISO-400; shutter speed-1/1000 sec |
So, as you can see, the shutter speed makes a huge difference in how a picture turns out. Now, I'll also show you a few of the outside photos so you can see how being in a brighter area affects the shutter speed numbers.
| Fstop-f/5.6; ISO-400; shutter speed-1/40 sec |
| Fstop-f/5.6; ISO-400; shutter speed-1/640 sec |
| Fstop-f/5.6; ISO-400; shutter speed-1/4000 sec |
So, you can see that the difference in shutter speeds between inside and outside vary by huge numbers. When I started on a shutter speed of 1/4 seconds like I did inside, the picture was actually completely white. I think I learned a little today with this "assignment" and I hope that maybe this has helped someone else also.
