I think I came up with a mix of the two edits.
All I did was duplictate the layer and then adjust the levels (RGB) '0' '1.68' '182'
Then I duplicated the adjusted layer and set the blend mode to soft light.
I repeated this step and set the opacity at 67%
One more duplication but this time I removed the model from the picture.
(I did this to achieve a very clean, white backdrop.) (Still set a soft light 100%)
