I recently started an Intro to photography course. The first lesson included a discussion on Depth of Field. I decided to take my Digital Rebel out for a series of shots at different f stops. I was looking at the photos and decided to print the f stop and shutter speed on each photo. I opened the EXIF information in Adobe Photoshop Elements and was surprised to see a value for the f-stop and one for the aperture value that were different. I thought that the f-stop and aperture were one in the same, and I would have expected them to be the same value.
If you look at the properties of the file in windows it itemizes an f-number and lens aperture separate, but the values are the same.
Can someone explain the difference between an f-stop and aperture, and why Elements is showing a different value?
Whats the differnece between f-stop and aperture?
