"Bracketing"-Shooting the scene several times with different F-stops/T-stops to create a range of exposure effects.
F-stop-The amount of light transmitted by a lens based on a simple mathematical calculation. Focal Length of lens divided by the diameter of the aperture.
But different lenses will take in different amounts of light depending on the number of elements in them. So two lenses with an aperture of f4 may actually allow different amounts of light to pass through them. One might create a brighter image than the other.
T-stop-Similar to F-stop but a T-stop is measurement of the actual amount of transmitted light for a particular lens as opposed to the theoretical calculation of an F-stop.
T-stops are used mostly in the motion picture industry.
