Shutter speeds - 1/1000s

[cubezero3]

Modern cameras offer a wide range of shutter speeds, ranging from 30s all the way down to even 1/8000s in some cases. Say, I want to take a photo of a building at 5s. I'd expect it to read at five seconds.

What about 1/1000s? Should it to be read like a fraction? At one thousandth second?
What about 1/4000s then? At one four thousandth second?
What about 1/125s? At one one hundred and twenty fifth second?

Shutter speeds are not read like fractions. Read the denominator like a regular number but add 'th'.

1/30s = "thirtieth of a second"
1/125s = "one twenty-fifth of a second"
1/250s = "two hundred fiftieth of a second"
1/2000s = "two thousandths of a second"

However, you'll also hear photographers simply drop the 'of a second' and just talk of a shutter speed as a regular number - 'thirty', 'two fifty', 'one thousand', etc.

The f-stops are read like the letter, plus the number.
f/2.8 = "eff two point eight"
f/8 = "eff eight"
