I am setting up ThumbsPlus options and preferences, and I have wondered this before. What is the difference between F-stop & Aperture, and between Shutter Speed and Exposure Time? I understand each word/term singularly, but don't know the fine differences. Thank you.

| They are the same. f/8 == an aperture of f/8. Exposure time of 1/125 seconds == Shutter Speed of 1//125 seconds. |

F-stop and aperture are the same thing.
Shutter speed and and exposure, well same thing also!
If you want a shallower depth of field, u use a bigger apperture (or smaller F number) and if you want to freeze movement you use higher shutter speed, or a smaller exposure!
Am I right? |

Thank you. I guess it must be a very detailed difference. I meant to say that I knew aperture and f-stop were essentailly the same, and shutter speed/exposure the same. In the EXIF data, they aren't "exactly" the same figures; I just think it is a matter of detail then. I thought maybe there was a bigger difference I didn't know about. For instance, one of my images shows:
F-stop 2.8
Aperture 3.0000
Shutter speed 1/955.43
Exposure time 1/1000

The digital camera allows minute variations in f:stop and shutter speed that were not available on traditional cameras. The aperture and exposure time fields are what the camera actually used, the f:stop and shutter speed fields are the traditional equivalents, rounded up or down to nearest equivalent.

Thank you! I had thought it was that, but since I don't know dSLR's, I wasn't sure if there was more to it or not. Thanks everyone for the help.
