Can you clear up my misconceptions please?
The way I understand it, Shutter speed is simply how long the shutter stays open when you hit the button.
ISO I thought, was Film Speed, and I assume that in the Digital world, the setting causes the camera to mimic the properties of the film ISO you set it to.
I think I'm starting to understand it. Basically you want a low ISO to produce the finest quality images. A higher ISO will result in a grainier image, but it will work better in low light applications where lengthening the shutter speed would produce a not-so-sharp image.
F-stop controls the aperture and by extension the Depth of Field. a Higher F-stop will produce a larger depth of field meaning more things will appear in focus in the image.
am I at least close with these statements so far?
this article illuminated much for me
