Hi... was puzzled on how people calculate f-stop value?
For example a f5.6 + 2 stops equals to wat no.? what is the formula used?

When people say '+' I usually think to open up, not stop down. So my answer would be f2.8. You should clarify your '+' is to let in more or less light, cheers.

Then there's stuff like 1/2 stops or 1/3 stops in camera settings, which makes it even more confusing.as answered it's f/11.
I guess for stuff like F-stops, the easiest way to get around them is to memorize the whole range? It'll come to you after a while

If I'm not wrong, for 1/3 stops, it goes something like this: (correct me if I'm wrong)
f1, 1.1, 1.2, f1.4, 1.6, 1.8, f2.0, 2.2, 2.5, f2.8, 3.2, 3.5, f4, 4.5, 5.0, f5.6, 6.3, 7.1, f8, 9, 10, f11, 13, 14, f16, 18, 19, f22
I have a question here: do these terms 'increase by 1/3 stop, 1 stop, 2 stops' appply to , say, shutter speed and ISO too?
I see. So in summary, 'Increasing by 1 stop' means essentially doubling it for shutter speed and ISO, but in the case of aperture, it means multiply by 1.4. Have I got it correct?yes. for ISO settings, "one stop faster" is equivalent to doubling the ISO number, eg. 400->800. for shutter speed, "one stop faster" means you should double the exposure time, eg. 1/30s to 1/15s.
