so this is aimed at normal cameras both dslr and slr but also covers drones, basically anything that can be adjusted and uses
ISO : SHUTTER SPEED : APERTURE
otherwise known as the exposure triangle.
there are a couple of links below for people to read up on and watch an explanation on you tube, there are also thousands out there some are better than others and others may suit your personal skills better than others.
Definitely worth reading until you understand as these are the fundamentals behind a well exposed image.
If you have a reasonable camera with auto settings it’s always handy to set on auto, note the settings it comes up with then have a play around these settings to see how the changes you make alter the images.
Hope this helps if not ask away
