>>2877805dodging is lightening and burning is darkening, these are old darkroom terms but that's how the photoshop tools are named. you don't have to use those tools though, there's lots of techniques. but this kind of editing is de rigueur for any serious art photography, as the attached image should demonstrate
for instance you could lighten those trees in the foreground a bit to make them pop more
dodging and burning can be used to bring out the contrast between different parts of the photograph, you could darken the mountaintops and brighten up the sky to make the peaks stand out better.
