Hi! I've been using the shutter override option to do a 50 seconds exposure. And I noticed something strange in my pictures.
On the upper right corner, there is a blue cast "light" visible. I tried to reproduce the problem, and the problem is still visible. Then, I tried to turn the noise reduction on, and the problem disapeared!
Strange thing... anyone else noticed? And how could it be explained?
I post here two pictures, the first was taken with a cap on the lens and the NR turned off, the second one was taken with the nr turned on. I brightened both pictures in order to see the problem better.
