Ik heb even voor je gezocht en dit gevonden op het internet: The option is available through the multiple exposure option where you can set it to take either 2 or 3 shots. Intervals can be up to 10 minutes. This is on page 121 of the user's manual. De D5000 en de D300 bijvoorbeeld kunnen veel meer foto's maken en voldoen denk ik veel meer aan jouw verwachting (maar daar heb je niks aan, want jij hebt de D90).
Je zult dus iets moeten aanschaffen. Ik heb even op het internet gegoogled en het volgende gevonden:
There are several after-market remote timer cords that you can use to accomplish that. The Nikos N10 and AP-TR3N are two of them.
Een andere optie: Satechi TR-M Timer Remote Control for Nikon D90 (Electronics)
"I bought this product to act as an intervalometer for my Nikon D90 for time-lapse photography. There aren't many products currently that can do this for the D90, as a result of Nikon changing the remote cable connector. You can do time-lapse with Nikon's camera control software, but you'd also need to lug around a laptop and pay $170 for that minimalistic software. The Satechi product was the cheapest remote timer / intervalometer I could find, and its functions seemed to fit what I wanted so I bought it. Overall I'm very satisfied".
Het googlen op "Remote Interval Timer D90" levert je een aantal opties op.
