Top one, same difference to the Canon image, only top to bottom instead of L,R.
anyways pushing sensors (yes iso 6400 and small amount of exposure IS pushing it to it's limits) to there max will usually lead to some odd behavior.
there is no iso 6400 sensor. Just a very low exposure amplified (via amp or software) a LOT.........
K10 had a red l left side, blue right side on poorly exposed high iso then pushed images.......
As to banding. seems to be a problem w/ black point correction on the sensor columns. Theory was w/ the k10 there were not enough "dark" samples at the ends of the sensor columns to correct the black point offsets (at least at low exposure, high boost).
this type of banding seems to be an individual sensor problem so some can have none to horrible.
Using my old D as an example, I had really clean high iso till it was repaired and the sensor swapped out. Now it bands a bit at high iso/exposure boost images.
If you notice banding is just inherent in the tech. why else would generic software have "fixes" for it.....
