Things I've learned in 4 days with the Nikon D90

• I am addicted to shallow depths of field. It's the most noticeable difference in the photos I can take with the D90 versus my old camera, and I'm afraid I can't stop.
  
• The remote is the most useful accessory I think I will ever buy for this. The heft of the camera seems to exacerbate the shaking when the shutter button is pushed.
  
• Tripods are invaluable.
  
• A fantastic camera alone will not make you a fantastic photographer. The overall quality of my photos has declined, though I suspect I will more than make up for it once I've figured this thing out.
  
• I need a close-up lens. Something to consider the next time I have a spare $500 lying around.
  
• The Quantity Method is still my photographic technique of choice. The D90 will be better for this than my previous camera (which only had a 3-photo burst mode). :^)
• I like having fully manual control over zoom. It's quicker and easier than a motor.
• I should stick to auto-focus.
• It's always going to be hard to photograph falling snow.
• I need more cats. The current one is starting to turn away and hide when he sees the camera coming.
