I have spots and dust marks in the same spots on my images. They're not always obvious but if they are, it's easy enough to "clean up" the photo in Photoshop. I've gone through the steps for in-camera sensor cleaning and used a blower bulb but they still appear in test shots. I've found opinion is divided between doing it yourself and sending the camera to Nikon. I hate the idea of being without the camera for a couple of weeks but I may eventually have to break down and send it to them. Curious what the advice would be in this forum?
