Re: PWP8 Beta 05-Jun-2019

I was helping another PWP user with Lens Distortion and Warp and noticed a difference in Preview when adjusting Lens Distortion Scale Factor between PWP8 and PWP7.

PWP8:

PWP7:

The PWP7 Preview was expected for the Lens Distortion settings shown:
Scale Factor = 0.8354
3rd Order Coefficient = 0.3842
5th Order Coefficient = -0.1590

Edit1: The PWP8 Preview changes to the expected view when Method is changed from Polynomial to Curvature.

PWP7 Lens Distortion had several problems that I fixed in PWP8 -- the Compute button was broken and the scale factor was being applied in such a way that it altered the distortion settings.
