Digital photography, like all photography of course, requires understanding exposure. With most automatic modes in most cameras you can get a quality photo, but not necessarily one that captures the full range of light that you see. I confess the histogram on many of my photos, especially before post-processing, tends to be bunched up, left, center, or right! So I've been reading and working on it. The book Exposure Photo Workshop: Develop Your Digital Photography Talent is terrific. It shares examples, explains settings that were used, and reasons for the settings. It's a good resource.
