The newly released "Learn & Explore" iPhone/Touch app from Nikon gives you access to information that was previously only available on the Nikon USA website.

You can read an article on getting the most from travel photography while you’re on vacation, adjusting depth of field or selecting the right shutter speed when taking photos at a sporting event, or advice on the right aperture for indoor photography.

Photography information at your fingertips and on the go.

In addition to articles on the fundamentals of photography and shooting techniques, you can read the latest issue of Nikon World magazine, complete with images and audio slideshows.

It also comes with a complete photography glossary.

And best of all, it's FREE!
