The general approach was to primarily blend the properly exposed image areas of the 'before' and '-1' images using a symmetrical tone range mask and secondarily blend the '-2' image highlights using an asymmetrical tone range mask with the corresponding '-1' image areas. The mask creations are not necessarily intuitive and are image set specific. avoiding halo and tone reversal artifacts. The only real difference from the above workflow to the DPR OP's method was to better define/form Mask1 and Mask2 for the blending of the exposure images. or Both use a slightly blurred 'contrast mask' and Composite-SoftLight to tone balance image elements brightnesses on the resulting (4) image. Others could use the HSV BrightnessCurve transform. PWP5 users could also adjust the Final Shaping Curve to a preference before clicking OK.
