The best way to learn is to first learn your camera and second to actually keep track of exposure settings (aperture and shutter speeds) and then compare them to the results. Change the settings and keep clicking on the same exact subject to see the differences.
Its so much easier these days with DSLR’s and instant gratification. Back in the day I used to carry around a notebook and used to record exposures every time i’d take a picture and then keep track of pic numbers, just like a check book, even recording “void” pics.
