Thought I would get serious with darks and flats now that I have a lightbox. Just using the camera lens on the Canon 600D and taking flats. Displayed it as a reasonably flat neutral gray and noticed a small white speck 1/3rd of the way in on the frame. Suspected something on the sensor, so tried it with a number of lens, and sure enough the spot is there.
Then I thought that if it was dust on the sensor the spot would be black not white !! So is is a hot pixel ? Checked the darks and nothing there.
Confused
anybody got any ideas ?
Edit: I was using Maxim DL, somehow I had drawn a tiny box on the frame, was able to distinguish it when I enlarged the frame, still trying to see how I managed to do it though.
Thanks
Roger
