Hi,

All the images from myD200contain the same red, blue and green pixels in the same locations regardless of image format (raw vs. jpg), size, etc. I'd appreciate any thoughts on what might be wrong, and if this could be due to a dirty sensor or if it may besomething more serious. Attached is an example.

Thanks!

Hey GB148,
These look like hot or dead pixels to me. There is a free utility you could use that tests for this.

Good Luck!

agree'd, they appear to be hot pixels. It is not to uncommon for this to happen, it happens with my D200 during long exposures but not on every picture. you can either clone them out of each picture or send you camera to nikon and they will remap the sensor and it will get rid of them.
