Help regrading exposure(Photography).Read below?

I'm new to photography world and i recently purchase Nikon D3200.
Well, my question is how to balance the exposure of a photo in different situation.
I read an article of Sunny F16, where it states that at F16 your shutter speed will be 1/ISO ie if you set ISO - 100, then shutter speed will be 1/100 or 125 at f16.

Then what about shutter speed at other light condition such as when i set aperture to f11(bright cloudy), f8(cloudy), f5.6 etc and ISO is 100.

Is F16 rule in different light condition work-
eg) suppose i set f8 ie overcast and ISO - 100 then shutter speed will be 1/400 or 1/500.

I tried in app called CAMERASIM, but failed to get right result.

From your question it seems that you do not know how to use your lightmeter.

The lightmeter is what you use to determine what "settings" use.

There's a link to a site that will help you learn to balance ISO, shutter speed and lens aperture to produce well exposed images.

This is NOT an app, but a tool to learn how to balance ISO, shutter speed and lens aperture before using your camera

For God's sake, you do not need to use the sunny 16 rule. Your camera has an internal light meter to measure exposure.

Time for you to read the instructions that came with your camera and learn how to use it.

Basically, you set the ISO to Auto or to a mid range such as 400.
Then you use the camera's internal metering to get the correct Aperture and/or shutter speed.
Read your instruction manual to find out more.

I agree that you should let the light meter do some of the work for you, but the best way to learn this is through trial and error. If you set the camera up to manual, the light meter will still tell you when the image is correctly exposed - it's just won't try to correct things when it isn't!

These "rules" that you've read are a little awkward to deal with, because while many of them hold true, if you are trying to be creative then more often than not you'll be ignoring them and setting the aperture and shutter speed to suit the occasion!
