Nikon D70 for Night Photography

Means they'll let you go up to ISO 3200 in 1/3 stop increments, but they
won't come right out and call it ISO 3200. I don't know if this means
there are formal standards for stating ISO speeds for digital cameras,
or if it's their own choice.

I do believe that it means they use software to achieve ISO3200. You could
take the image at ISO1600 and achieve the same results [theoretically] in
photoshop. ISO1600 and below are acheived by increased gain at the sensor,
which should yield better results as it will capture more information than
using software, which gains no information.
