Hi all:
I just joined this Nikon forum and this is my first post. I just got a D100 and so far I love it. I've looked for dead pixels and have identified several potential bad ones but am not SURE about it because the intensity will vary from image to image, sometimes not appearing. The potential bad pixels will show up at the same spot but their intensity will depend on the lighting. My question is...what is the best way to determine FOR SURE if a pixel is dead? In other words, how can I be sure that the Nikon repair technicians will also see that same pixel as dead? Should I record an image with the lens cap on? Should I record an image from a dark gray card? Should I record 3 separate images using Red, Green, or Blue cards and then look for dots of certain colors?
