I think the 22 bit allows more image preprocession before Saving, but If the save is raw in 12 bit format, I don't Understand what is going on there. jco

In the middle and right charts: a) the same analog signal is represented as the black line b) the horizontal axis indicates the area of each digital pixel c) the vertical axis represents the color values that the analog -> digital conversion can return, black at the bottom and white at the top d) the grid lines for the vertical axis on the right are closer together than the ones in the middle chart to show the finer gradations of output color possible with the e) the red dots show the output values for at each pixel under either 12-bit or 22-bit digital output -- Thanks, DougF (KG4LMZ) Thanks, Doug. So the dynamic range is the same for 12 vs. 22 bit conversion, but the 22 bit conversion allows more subtle shading. I have never been discontented with the shading rendered by my D. Is the 22 bit converter much ado about nothing?
