Choosing the Nikon D90 as your first DSLR is a great choice as it is a camera that allows for lots of growth with its ability to out of the box trigger a remote flash, allow settings changes by viewing its low power using top LCD as well as its dual control dials, all things no other DSLR under $1,000 has. Irfan brought his D90 and two lenses for our first DSLR Photography Lesson on a very pleasant St. Petersburg evening, not too hot, not too windy.
He also brought some knowledge of photography terminology (aperture, ISO). We took what he knew and expanded on it during the lesson, plus of course adding a good bit more information too. He seemed to absorb it all well.
As always I showed proper and safe lens changing techniques and how to best hold a DSLR camera for maximum stability, which right off the bat makes you at least look like a pro shooter.
