There’s a lot of resources out there for people who want to get to know their SLR just that much better — ranging from books to about a gazillion (that’s a technical term) YouTube tutorials — but not a lot of people seem to know about Nikon’s own Digitutor website. The Nikon Digitutor offers helpful flash tutorials about all of the different aspects of your Nikon camera.
Everything from the basics to little tips and techniques are covered, so if you’re using a Nikon from the last 5 years or so, head over to the website and see if the Digitutor can’t teach you something new about your shooter.
That's a really useful site, Cris. I don't have a Nikon, but I wish Canon had something similar.
