This question already has an answer here:
Now I am a proud owner of Nikon D5300 DSLR equipped with an 18-55 kit lens. This is the first time I am dealing with DSLR. I don't want to use as a mere point-n-shoot camera, but want to use it to its fullest extent. I feel the need of taking a full-length, in-depth online free photography course which will take me to the DSLR world. Can anyone please suggest me any such course which explores the key areas in DSLR photography?
