Larry, for a better comparison you should calibrate a bt1886 curve which has average gamma the same as your power law gamma calibration. What you have in your picture is probably a slightly above 2.3gamma bt1886 compared to 2.22 power law, so it isn't really a comparable comparison. What you will probably see when you calibrate an avg 2.22 bt1886 curve is that more shadow detail is exposed than your power law gamma.
