As suggested by Rob, I did setting and ran my tests
again for different exposure exposures.
All these values are taken from FILE created by the
"DeadPixel tool" instead of values shown against
"Result" in dialog box.
Settings are WB is sunlight, Saturation middle,
Sharpen is 0, Contrast 0, sRGB, iso 200asa
T I F F R A W
----------- ------------
Exp Time NRoff NROn NRoff NROn
1/10 0 0 0 0
1/8 0 0 0 0
1/6 0 0 0 0
1/4 2 0 0 0
1/2 18 0 100 0
1 100 100 100 100
2s 100 100 100 100
After 1s, BadPixels remains 100.
My question is 100 bad pixel a bad count?
Should I think of exchanging for another one?
Thanks
Ramesh
