BASICS OF EXPOSURE

 When I fist started fiddling in photography, I didn't really bother much about the settings, just chuck it on auto, micro, or whatever and it should be fine (which was really not the best choice)
I did so much research on what those buttons meant and no place would show me the basics, the simple explanation of what it really is.. Only technical terms which then gets you off track from what you're actually supposed to understand.. Exposure!
Exposure is made up of the big 'Trio': ISO, Shutter Speed, Aperture.
So here's what they actually do to your photos to make them a lot.. nicer:
ISO is Sensitivity: Controls how sensitive your camera is to light.
It's too light in the place of shooting? Turn the ISO up to around 100/200. Is it too dark? Turn it up to 800/1600. The norm is 400 for a general overcast day.
Note: Anything over 1600 can create more visible noise
(imagine a photo and tiny grains over the top - basically bad quality image)
 
Shutter Speed is Movement: Controls the length of time that light enters your camera.
The narrower the opening is, the more still the image will be.
1/2000 is a fast shutter speed which in turn gives a still frozen image
1/2 captures the movement, which results in a blurred image (best used with narrow aperture)..

Aperture is Focus: Controls how much light enters your camera.
Like I said before, a slow shutter speed is best used with a narrow Aperture like f/16 or f/22.
The wider the Aperture, the more light enters and gives you a blurred background (shallow depth of field = less in focus)
f/2.8 - less in focus ; f/22 - more in focus
 
If you have any other questions, leave them in a comment below and I can either reply, or do a in-depth post about it!
